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.

Korguz - Tuesday, July 23, 2019 - linkMaxiking, wow you hate amd.. but to be fair, nvidia is also guilty for the re brands as well, probably not as bad as amd.. but still bad :
510 -> 605 (Fermi GF119)
GT520 -> GT610, GT620 (OEM), 705 (Fermi GF119)
GT530 -> GT620 (retail) (Fermi GF119)
GT440 (DDR3) -> GT630 (DDR3), GT730 (DDR3, 128-bit) (Fermi GF108)
GT440 (GDDR5) -> GT630 (GDDR5) (Fermi GF108)
GT545 (DDR3) -> GT640 (OEM) (Fermi GF116)
GTX560 SE (OEM) -> GT645 (Fermi GF114-400-A1)
GT630 (Kepler) -> GT740 (Kepler GK107)
GT630 (Kepler rev 2) -> GT710, GT720, GT730 (128-bit & GDDR5) (Kepler GK208)
210 -> 405 (OEM) (Tesla GT218)
GTX680 -> GTX770 (Kepler GK104)
but i am sure you will find some way to refute and ignore this fact.. but what ever man.
Spunjji - Friday, July 26, 2019 - linkIf you're insisting that the RX590 is a rebrand, then congratulations, so are the Super cards - because Nvidia have done the exact same thing here (wait for yields and consistency to improve and use that to edge out a little more performance from the same silicon).
You can spot the Nvidia shills because they show up yelling as though only AMD do rebrands, and as if a rebrand is somehow a form of robbery. Fact is it's been something both companies have done for decades now. Pretty sure G92 was the first product to go through three names (8800 GTS 512MB / 9800 GTX / GTS 240) and Nvidia's low-end products are even more prone to this.
ballsystemlord - Saturday, July 27, 2019 - linkFWIW: AMD's 500 series was clocked higher because the process had been improved, not because AMD wanted to make life worse for us by sandbagging on the 400 series. The 590 was just a cheap way to place something in between the 580 and Vega 56 and it was on a smaller node, so it's not *just* a rebrand. The RX 200 and 300 series were mostly rebrands, but if I'm an early adopter, how much trouble is it to check and find out that a card is just a rebrand and then not buy?
jordanclock - Tuesday, July 23, 2019 - linkThat is a lot of words to be wrong.
These cards exist because yields got better since the architecture was launched last year. Not because of some sort of conspiracy by Nvidia to trick people into upgrading already. It's not bait-and-switch, mostly because you don't know the definition of bait-and-switch.
You don't need a card "without the ray trace crap being shoved in" because in games without RTX features, the RT cores don't do anything to harm performance in any way. The RTX 2080 performs essentially the same as a theoretical GTX 2080.
I won't address the rest of your tirade because it's clear you're just angry that Nvidia didn't come ask you personally what you wanted in a video card. While RTX hasn't been exactly a success, we should be encouraging Nvidia and AMD to find ways to improve game visuals besides higher resolution
GreenReaper - Wednesday, July 24, 2019 - linkThey might need to have stocked up a sufficient number of chips of a certain quality in order to satisfy demand. It's little good announcing a card that renders another card redundant and not having enough chips to sell. You'll just get people buying neither of those cards.
YB1064 - Tuesday, July 23, 2019 - linkGiven the performance of AMD, it doesn't look like NVIDIA had to release anything. Their top card Radeon VII is supposed to be EOL. Looks like AMD are still far behind. Anything good on the horizon from AMD?
Maxiking - Tuesday, July 23, 2019 - linkYeah, that fabricated 4.7ghz boost on Ryzen 3950x.
designgears - Tuesday, July 23, 2019 - linkThey are behind at the highest end, but they're competitive in the mid-range which is where all the money is for them, so not a big deal when you look at it like that. They also power the current gen xb1/ps4 and next gen.
Maxiking - Tuesday, July 23, 2019 - linkObviously the money aren't there, the gpu division is constantly operating at a loss.
Rudde - Thursday, July 25, 2019 - linkRadeon isn't operating at a loss. Apple reportedly paid a part of Vega development and they needed a gpu for their apus (i.e. all mobile parts). Vega is great at compute, earning AMD some extra revenue. Google placed a large order.
Sony and Microsoft paid a part of Navi development and placed a huge order. Navi will be used in apus once again, bringing in some revenue.
Desktop gpus is not AMDs only gpu market, they need the same development for their other divisions.
