In the large PC forumPCMR on RedditOne keyword has dominated the top posts for days:Fake Frames
.
Nvidia's CEO Jensen Huang got the whole thing rolling as part of the.
Fake Frames
Translated, this means fake or artificial images and means frames that were created entirely using the functions of an artificial intelligence.- Face it
real
Frames that were created in the classic way via the render pipeline of a graphics card using its computing units. - The latter are calculated in real time based on the game world and our actions within it. The former, or pure AI images, on the other hand, are based on images created via the render pipeline and therefore only have anything to do with our input via mouse, keyboard and gamepad in the game via this intermediate step.
The stumbling block
Above all, a comparison in Huang's imagination has turned the discussion aroundFake Frames
fired up: It's about the comparison of the slowest Blackwell GPUfor 649 euros with the previous Nvidia flagship, which can be placed in the price range of around 2,000 euros.
Before we take a closer look at this comparison, we recommend our detailed expert talk on the presentation of the new RTX generation:
RTX 5070:Performance on par with the RTX 4090
Shortly before Huang reveals all RTX 5000 models and their prices, the crucial moment comes.
The central question is how the new Blackwell graphics cards compare with the previous models or with the current top model RTX 4090.
If you want to watch the whole thing for yourself in full context, you have to skip to minute 17:40 in the video embedded below.

At around minute 18:45, Huang makes the much-discussed statement.
The RTX 5070 of the Blackwell generation therefore achieves performance at the level of the RTX 4090. At $549, the 5070 only costs around a third of the price of the RTX 4090 of $1,499.
Immediately afterwards comes a very important addition from Huang: Without the use of AI, this is impossible (more on that in a moment). But what sticks with many people is the following picture:
Performance is not the same as performance
The performance comparison in the picture raises an obvious question: The RTX 4090 has, among other things, 16,384 computing units and 24.0 GB of VRAM - how can a graphics card with a similar architecture and only 6,144 computing units and 12.0 GB of VRAM be equally fast?
The answer is primaryMulti Frame Generation
or MFG.Because this new function only runs on RTX 5000 models, but not on the RTX 4090. Up to three additional images are calculated entirely using AI.
You can find out everything about how MFG works here:
The big catch:Most games do not support multi frame generation. Natively, things will be loud when the RTX 5000 is releasedComputerbaseonly Alan Wake 2, Cyberpunk 2077, Indiana Jones and the Great Circle and Star Wars Outlaws.
According to the current status, up to 75 titles can be made fit for the new technology using the Nvidia app, even without native support.
But that doesn't change the fact that, given the overall market, the RTX 5070 can only make use of MFG in very few games. Or to put it another way: In most cases it will probably be significantly slower than the RTX 4090 despite the new GDDR7 RAM.
FPS isn't everything
Another circumstance makes things more difficult: a smooth gaming experience is primarily due to the low latency of our inputs.
- The longer it takes for a command via mouse, keyboard, gamepad etc. to be implemented on the monitor in the game, the more sluggish it feels.
- However, the rule of thumb that more FPS also ensures lower latency cannot be easily transferred to images generated by AI, since their creation itself takes time and because they are only indirectly based on our input in the game.
- This is shown in concrete figures, among other things, by a comparison of the RTX 5090 with the RTX 4090 in Cyberpunk 2077, which the well-known YouTube channelLinus Tech Tipscould do:
Although the RTX 5090 Thanks MFG achieves more than twice as high FPS values as the RTX 4090, the latency of the inputs (PCL value) is almost the same on both systems at around 36 milliseconds.
Latency isn't everything and MFG left a good impression in an initial test by the technology experts at Digital Foundry, as you can read in more detail here:
Given all these special features, it is understandable that Nvidia's (too) simple breakdown of the statementThe RTX 5070 delivers the performance of the RTX 4090
The RTX 5000 presentation caused a lot of criticism in the community.
Regardless, we are very excited to see how well the Multi Frame Generation with RTX 5000 will perform in practical use when it comes to a noticeable improvement in the gaming experience, both in terms of the feel and the optical quality.
