קראתי את הביקורת של אננדטק והוא מסכם את זה יפה:
קפיצה של 20-30 אחוז בביצועים, לעומת 6-80 אחוז בשתי הדורות הקודמים:
So generationally-speaking, the GeForce RTX 2080 represents a much smaller performance gain than the GTX 1080's 71% performance uplift over the GTX 980. In fact, it's in area of about half that, with the RTX 2080 Founders Edition bringing 40% more performance and reference with 35% more performance over the GTX 1080. Looking further back, the GTX 980's uplift over previous generations can be divvied up in a few ways, but compared to the GTX 680 it brought a similar 75% gain.

But the performance hasn't come for free in terms of energy efficiency, which was one of Maxwell's hallmark strengths. TDPs have been increased across the x80 Ti/x80/x70 board, and the consequence is greater power consumption. The RTX 2080 features power draw at the wall slightly more than the GTX 1080 Ti's draw, while the RTX 2080 Ti's system consumption leaps by more than 60W to reach near-Vega 64 power draw at the wall.
אין בהשקה שום תמיכה ב DLSS או ב RT:
Putting aside those who will always purchase the most performant card on the market, regardless of value proposition, most gamers will want to know: "Is it worth the price?" Unfortunately, we don't have enough information to really say - and neither does anyone else, except NVIDIA and their partner developers. This is because the RT Cores, tensor cores, Turing shader features, and the supporting software are all built into the price. But NVIDIA's key features - such as real time ray tracing and DLSS - aren't being utilized by any games right at launch. In fact, it's not very clear at all when those games might arrive, because NVIDIA ultimately is reliant on developers here.
RT כנראה יהיה מעשי רק אם המשחק יתמוך גם ב DLSS, וזה בשליטתם של המפתחות ולא של נווידיה (בהנחה שהמפתחות ירצו להשקיע זמן וכסף בהכנסת הטכנולוגיות הללו למשחקים):
Even when they do arrive, we can at least assume that enabling real time ray tracing will incur a performance hit. Based on the hands-on and comparing performance in the demos, which we were not able to analyze and investigate in time for publication, it seems that DLSS plays a huge part in halving the input costs. In the Star Wars Reflections demo, we measured the RTX 2080 Ti Founders Edition managing around a 14.7fps average at 4K and 31.4fps average at 1440p when rendering the real time ray traced scene. With DLSS enabled, it jumps to 33.8 and 57.2fps.
משלמים יותר, מקבלים פחות:
The easier takeaway is that these cards would not be a good buy for GTX 1080 Ti owners, as the RTX 2080 would be a sidegrade and the RTX 2080 Ti would be offering 37% more performance for $1200, a performance difference akin upgrading to a GTX 1080 Ti from a GTX 1080. For prospective buyers in general, it largely depends on how long the GTX 1080 Ti will be on shelves, because as it stands, the RTX 2080 is around $90 more expensive and less likely to be in stock. Looking to the RTX 2080 Ti, diminishing returns start to kick in, where paying 43% or 50% more gets you 27-28% more performance.
רק ל early adopters:
imately, gamers can't be blamed for wanting to game with their cards, and on that level they will have to think long and hard about paying extra to buy graphics hardware that is priced extra with features that aren't yet applicable to real-world gaming, and yet only provides performance comparable to previous generation video cards.
