Boasting up to six times the performance of the older GTX 1080 series graphics card, Nvidia’s latest GeForce RTX 2080 and RTX 2080 Ti are GPU beasts. Even though you may not need — or experience — such massive performance gains on current titles, enthusiasts eyeing the new RTX cards are actually buying into Nvidia’s vision for the future of gaming, which is centered around the new ray tracing capabilities of the RTX chips’ Turing architecture.
But even at the high end of Nvidia’s new gaming GPU line, there is a sizable difference in what the standard RTX 2080 Founders Edition is capable of compared to the RTX 2080 Ti Founders Edition. Some will likely want to gravitate towards the Ti’s improved specifications, but that comes with a hefty $400 price premium. We’ll break down just how the two top-shelf RTX GPUs stack up.
Performance
Because it’s more densely packed, the RTX 2080 Ti Founders Edition performs slightly better in our early benchmarks compared to its non-Ti variant. That’s to be expected, given that the Ti packs in more CUDA, Tensor, and RT Cores.
When benchmarked using 3DMark, the RTX 2080 Ti performed consistently better across the three tests. This means that the Ti variant had a performance improvement over the base model ranging from 13 percent for the Fire Strike test to up to 31 percent for the Sky Diver test.
When we looked at our gaming results using Deus Ex: Mankind Divided, performance between the two high-end RTX chips were on par at lower resolutions, but the difference was significant at 4K resolution. On Ultra, both chips posted the same results at 1080p, and the Ti variant started to edge ahead under 1440p. Under 4K resolution, the RTX 2080 Ti outperformed the standard model by 29 percent, suggesting that the added Cuda cores and memory on the Ti variant make a more meaningful contribution to graphics performance at higher resolutions and during more GPU-intensive tasks.
Interestingly, though, performance between the RTX 2080 Ti and the RTX 2080 was roughly on par using our Civilization VI test. With the 4K Ultra settings enabled, the Ti variant scored 74, compared to 76 on the non-Ti chip. Performance was similar using the
Both the RTX 2080 Ti and RTX 2080 will be able to handle first-person shooters at 4K resolution and 60 frames-per-second. And as we’ve seen demonstrated by the Deus Ex: Mankind Divided results, games with Deep Learning Super Sampling (DLSS) built-in should see even bigger performance gains with the Ti version of the RTX 2080.
DLSS delivers better image quality improvements, smoother frames, and better anti-aliasing, thanks to the use of the the built-in Tensor cores and artificial intelligence. The Ti version of the the card has 576 Tensor Cores, versus just 384 on the non-Ti variant, giving it a bigger performance advantage in situations where the GPU would be taxed. In this case, some of these dedicated cores kick in to offload some of the strain on the GPU.

At the top of Nvidia’s graphics pyramid, both the RTX 2080 Founders Edition and RTX 2080 Ti Founders Edition support ray tracing, AI-enhanced image rendering, and the single-cable VRLink protocol to connect virtual reality headsets to PCs using a single USB-C cable.
The main difference between these two cards is in the number of dedicated Cuda, Tensor, and RT Cores. The Ti’s more densely packed cores gives it a performance advantage under some tests. The Ti version comes with six graphics processing clusters, each with its own raster engine and six texture processing clusters. Each texture processing cluster comes with two streaming multiprocessor (SM), with each SM containing a single RT processing core, 64 CUDA Cores, eight Tensor Cores, and four texture units. Essentially, as you go down the line in the RTX series, you’ll find fewer RT and Tensor Cores. The RTX 2080, for example, packs just 46 RT cores and 368 Tensor Cores, compared to 72 RT cores and 576 Tensor Cores on the Ti edition.
With more RAM — 11GB versus 8GB — and the ability to handle more operations per second, the Ti card should also perform better than the base RTX 2080 when it comes to ray tracing. Nvidia claims that the RTX 2080 is capable of 60 trillion RTX OPS and 8 GigRays per second, while the more capable Ti edition can handle 78 trillion RTX OPS and 10 GigaRays per second.
Given that there are no game available right now with ray tracing, we’re not able to get benchmark results for these cards. Once
Which to buy?
The Founders Edition of the RTX 2080 and RTX 2080 Ti are the top two Nvidia’s new line cards, but they’re also the two most expensive. The RTX 2080 Founders Edition retails for $800, while the Ti edition will cost $1,200. If you’re looking to connect two cards together, Nvidia’s Founders Edition cards use the NVLink connector, so you’ll need to add a $80 bridge for a multi-GPU setup.
Unless you’re pushing the performance boundaries with high resolution gaming, most gamers will likely experience little perceivable performance improvements with the Ti card at this time. Given the steep price premium of $400 between the two cards, you may be better served by spending the difference in cost in upgrading your SSD or system RAM, or even going springing for a previous-gen GTX 1080 or 10 80 Ti. That is, at least until more ray tracing games launch to justify this investment.
