The last two months have been a period of tit-for-tat in the PC video card industry. Both AMD and NVIDIA have been going back and forth, making announcements and launching products as part of a broader restructuring of the mid-range and high-end video card markets in response to the launch of AMD’s Radeon RX 5700 series of video cards. Performance is going up while last-minute maneuvering has brought prices slightly down, all the while the two major players in the GPU space look to solidify their product lineups and secure their competitive edge against their competition.
For all practical purposes, NVIDIA’s GeForce RTX 20 Super series has been the company’s response to AMD’s new video cards. A combination of a mid-generation kicker and a product stack realignment to go head-to-head with AMD, the Super cards have given NVIDIA’s product lineup a modest performance boost at almost every level. After launching the first two cards in this sub-series early this month with the GeForce RTX 2070 Super and GeForce RTX 2060 Super, NVIDIA is back again to launch the last (?) of the Super cards: the previously announced GeForce RTX 2080 Super.
Since gamers have had a couple of weeks to chew on this one – specs and all – there aren’t any last-minute surprises here. The GeForce RTX 2080 Super is a minor performance bump for what was the GeForce RTX 2080, offering a couple more SMs and higher clockspeeds to push performance a bit higher, while holding the price at $699. Truthfully, it’s not a card that’s going to light the world on fire or set any new performance records; but it’s a card that’s going to deliver better performance than the RTX 2080 did at this point yesterday, and it’s going to restore some breathing room between NVIDIA’s 2070 and 2080 cards, as the new RTX 2070 Super has all but made the vanilla RTX 2080 redundant.
|NVIDIA GeForce RTX 20 Series Lineup|
|GeForce RTX 2080 Ti||MSRP: $999
(Street Price: $1149)
|GeForce RTX 2080 Super||MSRP: $699|
|GeForce RTX 2080||EOL ($699)|
|GeForce RTX 2070 Super||MSRP: $499|
|GeForce RTX 2070||EOL ($499)|
|GeForce RTX 2060 Super||MSRP: $399|
|GeForce RTX 2060||MSRP: $349|
Unsurprisingly then, the vanilla RTX 2080 is on its way out. As part of the Super card launch, the RTX 2080 and RTX 2070 are being discontinued. So the RTX 2080 Super is for all practical purposes the new RTX 2080. Which is to say the fastest of NVIDIA’s semi-affordable high-end video cards, heir to the 80-card family name, and a part targeted at a mix of 1440p and 4K gaming.
And, as we’ll see, it is both the least and most interesting of the Super card launches.
|NVIDIA GeForce Specification Comparison|
|RTX 2080 Super||RTX 2080 Ti||RTX 2080||RTX 2070 Super|
|Memory Clock||15.5Gbps GDDR6||14Gbps GDDR6||14Gbps GDDR6||14Gbps GDDR6|
|Memory Bus Width||256-bit||352-bit||256-bit||256-bit|
|Single Precision Perf.||11.2 TFLOPS||13.4 TFLOPs||10.1 TFLOPS||9.1 TFLOPS|
|Manufacturing Process||TSMC 12nm "FFN"||TSMC 12nm "FFN"||TSMC 12nm "FFN"||TSMC 12nm "FFN"|
Starting from the top, let’s take a look at the specs. When NVIDIA launched their GeForce RTX 20 series cards last year, the 2080 and 2080 Ti were somewhat conservatively configured; both cards shipped with a few disabled SMs (among other things), which is to say that they utilized less-than-fully-enabled GPUs. This helps with binning, of course, but it also gave NVIDIA some breathing room to bump up their performance should they ever need to. Now, with the RTX 2080 Super, they are doing just that.
For the first time in a GeForce RTX 20 series card, we’re finally getting a fully-enabled TU104 GPU. NVIDIA is enabling the final 2 SMs, adding a further 128 CUDA cores to the pool, for a total of 3072 CUDA cores. With the final two SMs comes their respective PolyMorph engines and RT cores, so the RTX 2080 Super is coming to bat with everything the GPU can offer on the shading, texturing, geometry, and ray tracing fronts. The notable exception here will be on the render backend side of things; RTX 2080 already shipped with all 64 ROPs enabled – as well as the associated L2 cache – so there are no hardware improvements here.
Instead, pushing the card even farther are higher clockspeeds, coupled with a very generous 250W TDP. As RTX 2080 overclockers already know, TU104 can easily sustain clockspeeds higher than NVIDIA’s RTX 2080 reference clocks, however the cost is increased power consumption and all the drawbacks that entails. So for the RTX 2080 Super, the base and boost clocks have been bumped up by 9% and 6% respectively, and the card should now generally be able to sustain 1815MHz (or better) on most games – and this might be a bit conservative. Meanwhile, unlike enabling more SMs, this benefits every facet of the video card, so front-end and back-end performance is all getting faster.
The penalty for this is that the 215W TDP RTX 2080 is being replaced with the 250W TDP RTX 2080 Super. This happens to be the same TDP as the even faster GeForce RTX 2080 Ti, so it’s easy to see where this is going: NVIDIA is bumping up their overall performance, at the cost of some power efficiency. As we’ll see in our benchmarks, the situation is a little more complex than that, but not immensely so. Perhaps the wildest factor here is that unlike the RTX 2080 Ti, the RTX 2080 has trouble actually filling out its 250W TDP; NVIDIA boosted the TDP to ensure the card had sufficient power headroom for higher clocks, and they definitely succeeded. As a result, the card gets to run at full throttle a lot more than the original 2080, or for that matter the 2080 Ti or the 2070 Super.
Faster GDDR6 Memory Comes to Video Cards
But perhaps the most interesting change with the RTX 2080 Super isn’t even the GPU itself, but rather what NVIDIA is doing to feed the beast on the memory front. Since the first GDDR6-equipped video cards launched a year ago, every card has shipped with 14Gbps (or lower) memory. 14Gbps was the fastest speed grade available at launch from the major memory vendors, however it wasn’t the fastest speed grade on the roadmap. 16Gbps memory has been on the drawing board as well, and now with the launch of NVIDIA’s new card, we’re getting our first card with that memory.
For the launch of their new cards, NVIDIA has tapped Samsung’s new 16Gbps, 8Gbit chips for the new cards. With a 256-bit memory bus for the card itself, this keeps the RTX 2080 Super at the same 8GB of VRAM as the original RTX 2080, but it gives the card more bandwidth to play with. However in a rare move for NVIDIA, they’re actually being a bit conservative here on memory clocks – the RTX 2080 Super is only running at 15.5Gbps instead of the 16Gbps the memory is capable of.
According to NVIDIA, the reason for this ultimately comes from their decision to make the Super cards as straightforward a manufacturing upgrade as possible, spec’ing the cards such that board partners (including themselves) can use the same boards and coolers from their vanilla RTX 2080 cards. As a result, the RTX 2080 Super is built on a PCB originally designed and qualified for 14Gbps GDDR6. True 16Gbps memory clocks would seemingly require a new PCB, which for a 3% memory clockspeed bump (and less on performance) is not something board makers are going to want to spend the money on.
To be sure, I’ve clocked our card to 16Gbps with ease and without any problems; but then our standards for stability are not as high as NVIDIA’s (never mind mass production concerns). So for curious overclockers, there is a bit more memory headroom to play with here, with the usual warnings about overclocking. Meanwhile for everyone else, the net result is that the RTX 2080 Super has 11% more memory bandwidth than the RTX 2080 it replaces (and the RTX 2070 Super).
As a result of this and the higher TDP, the RTX 2080 Super tends to be more heavily GPU-bound than most NVIDIA cards. The higher memory speeds more than make up for the fully enabled GPU and its higher clockspeeds, so while no GPU has memory bandwidth to spare, RTX 2080 Super is rather well fed. It also means that overclocking is going to be a bit more one-dimensional, with GPU clockspeeds being the biggest factor by a significant degree.
Product Positioning, Availability & the Competition
As with the other RTX 20 series Super cards, NVIDIA and its partners are going to hit the ground running here with everything from reference cards to fully custom cards. These are the same TU104 GPUs using memory validated to run on the same PCBs, so board partners can quickly tap their existing 2080 designs to bring new cards to market. Similarly, card volume shouldn’t be a big issue – though as we’ve seen with the now sold-out RTX 2070 Super, demand is front-loaded, so there’s still the potential for sell-outs.
Also like the other Super cards, NVIDIA is once again be releasing their own reference card. Unlike last year’s factory overclocked Founders Edition RTX 2080, NVIDIA will not be overclocking their RTX 2080 Super or charging a premium for it. Their reference card is still going to be sold under the Founders Edition branding, however it should perform identically to any other reference-clocked cards. Meanwhile, as is usually the case, the cards will be sold directly by NVIDIA.
NVIDIA is also extending their latest video game bundle to the new card. The RTX 2080 Super gets a two-game bundle that consists of Wolfenstein: Youngblood and Remedy’s upcoming Control. NVIDIA for its part has been avoiding game bundles at launch for its high-end cards for most of the past few years, so it’s noteworthy to see them included here. As part of their overall product stack realignment, NVIDIA is looking to increase the value of their cards without actually cutting prices, so this is another way to achieve that.
Meanwhile the competition for the RTX 2080 Super is a mixed group. With the vanilla RTX 2080 on its way out (along with the RTX 2070), on the NVIDIA side of matters the competition is the RTX 2080 Ti above, and the RTX 2070 Super below. The RTX 2080 Ti remains NVIDIA’s fastest GeForce card by a good margin, however card prices have been wacky for months and it hasn’t stopped. Even the cheapest (new) card will set you behind by $1150, a $450 premium over the RTX 2080, a gap so large that if you have to ask which card to pick, you probably can’t spare the money. Meanwhile the RTX 2070 Super is definitely the spoiler to NVIDIA’s stack; the card offers performance just a bit under the original RTX 2080 for $200 less (perhaps it’s not too surprising then that the card is currently sold out).
As for AMD’s cards, technically AMD’s closest competition is the Radeon VII, which came to life as a surprise back in January of this year. The card offers generally RTX 2080-like performance for $699. However even before today’s RTX 2080 Super launch it’s arguably been stillborn in the consumer & PC gaming spaces – it just didn’t do anything better than the RTX 2080 – and the RTX 2080 Super puts the last nail in that coffin. Far more interesting at a fraction of the price is the new Navi-based Radeon RX 5700 XT. It’s not an RTX 2080 Super competitor, but it’s potentially an even larger spoiler than the RTX 2070 Super, offering a whole lot of performance for $300 less. Overall the RTX 2080 Super may be semi-affordable compared to the RTX 2080 Ti, however it’s still decidedly a high-end NVIDIA card, so perf-per-dollar isn’t a strong selling point here.

Zoolook - Thursday, July 25, 2019 - linkEssentially the GPU-division tided them over when the CPU-division didn't deliver, the new CPU cores where prioritized over developing the new GPU architecture for several years so it's no wonder they are behind on the GPU-side. Hopefully they will catch up for real in the next couple of years with the increased revenue flow put to good use.
rocky12345 - Tuesday, July 23, 2019 - linkLOL to funny I guess when a mid range card like the 5700XT was able to almost match the performance of AMD's top card that cost a lot more than the 5700XT AMD has a real problem there for sure. The only coars eof action for AMD was to remove the Radeon 7 form the picture as it served no more purpose other than triggering reviewers after the 5700 cards came out.
Now if I was Nvidia I would be some what worried as to what AMD has on the books and what the next move is going to be. If the mid range cards like the 5700's can topple AMD's top card and hang in there and beat Nvidia's mid top cards what will the Navi 20 chip be able to do. You have to know AMD is planning on doing to Nvidia what they have been doing to Intel right.
It has been proven and told by AMD themselves that they played Nvidia by showing higher launch prices as well as down playing the performance a bit to see how Nvidia would respond. I guess they had a good laugh after seeing Nvidia start the Super marketing and a really rushed launch to beat AMD to the punch line just to find out AMD played them in every way and lowered the prices just before launch and the performance was better than what they had shown in their slides by about 5%-7%.
Have you even looked at the reviews. The 5700 creams the 2060 and the 5700XT creams the 2070. The 5700 is slightly faster than the 2060S and the 5700XT almost catches the 2070S and with driver tweaks it probably will get faster than a 2070S because of the Navi's being a totally new card lineup. Like I said if small Navi is this fast you know Nvidia is worried about big Navi which is coming very soon as well. Rest assured though Nvidia will have something to compete with big Navi for sure they will never settle for being second best or not the fastest...their CEO's ego could not live with that.
michael2k - Wednesday, July 24, 2019 - linkYou are way too emotionally invested if you think the CEO's ego has anything to do with product design.
Paying for their second new HQ? That's NVIDIA's reason for never settling for second best:
That's a lot of money to pay off, and you don't get there by releasing second best cards for several generations.
But don't worry, NVIDIA has three tricks they can play:
1) Smaller process (either 10nm or 7nm) will give them the ability to drop voltage, power consumption, and die size, all of which reduce the cost of the part and improve profits at the low end of the scale.
2) Smaller process also gives them the headroom to boost clock and add more functional units without driving up power consumption, making their middle end competitive
3) Smaller process also give them more room to design bigger GPUs, which means they can keep releasing their Ti parts
All three means, of course, that even if they did nothing but die shrink, boost clocks, and increase the number of units, that they will remain competitive for another two years, on top of architectural changes.
Silma - Tuesday, July 23, 2019 - linkWhy hasn't NVIDA begun to sell 7nm cards?
Does AMD have a time-limited exclusivity contract with TSMC?
Or will it wait untill AMD launch cards faster than its own?
eastcoast_pete - Tuesday, July 23, 2019 - linkLargely because they don't have to. My guess is that NVIDIA has quite a number of 12 nm FF dies in stock (probably a lot, thanks to the crypto craze) and are now selling them before they start the next generation .
michael2k - Tuesday, July 23, 2019 - linkI'm sure part of it is their existing contract, as opposed to an exclusivity contract. 12nm is a much more mature process, and in that regard it makes sense when trying to make a large part to use a proven process. 7nm wasn't available when NVIDIA was designing their RTX parts, so there was no way to estimate yield or improvements over time in 2018 (when they released the RTX parts)
Now that the process is over a year old I'm sure they are working on a refreshed design to reduce power, increase clock, and add more or new functional units next year.
haukionkannel - Tuesday, July 23, 2019 - linkNvidia headmaster Also said in one interview that They can make 12nm chips much cheaper than 7nm chips... and that is good reason not to go for the newest new production technology.
rocky12345 - Tuesday, July 23, 2019 - linkTranslation is 12nm is good enough right now we do not want to invest in 7nm as in not worth it because our power usage numbers are good enough right now.
AMD on the other hand OMG our power numbers are through the roof we need a new node ASAP and that has worked out for them very well this time around. If Navi was on Global 14nm or 12nm the power usage would be insanely high for sure. TSMC's process is just better for GPU's than Global's. On the other hand TSMC's process not so good for CPU's as seen in Ryzen 3000 series and the lack luster clock speeds. Good thing those CPU's have a lto in them to make up for the lack of clock speed and they still perform like they are running at a higher speed than they are.
Rudde - Thursday, July 25, 2019 - linkTSMC 7nm HPC node is more optimized for power usage than GF 12nm. The same can be said about Intel 10nm compared to Intel 14nm. That said, TSMC 7nm is not far behind GF 12nm in performance.
DanNeely - Wednesday, July 24, 2019 - linkIIRC this is a fairly traditional pattern with AMD/ATI being more aggressive about moving to new processes early on while NVidia waits until they're more mature.
