RTX 5090 vs RTX 4090: Questionable RTX 5090 rasterization performance surfaces alongside notable ray tracing gain
According to the information posted on a
now-doomed Chiphell thread, the RTX 5090 scores more than 24,000 and 13,500 points in the 3DMark Time Spy Extreme and Speed Way tests, respectively.
Talking first about the Time Spy Extreme score, the
RTX 4090 Time Spy Extreme scores from the 3DMark database fall between ~22,800 and 23,300. Based on a score of 22,800 for the
RTX 4090 and 24,000 for the RTX 5090, the Blackwell GPU appears 5.3% faster than its predecessor. Of course, the result will be different if calculated with higher scores. But, for the sake of argument, we can assume a lower score for both the RTX 5090 and the RTX 4090.
Moving on to the 3DMark Speed Way test, a ray tracing benchmark, the RTX 5090’s reported score of 13,500+ puts the GPU 8% ahead of the fastest RTX 4090 in the 3DMark database. Once again, since the RTX 4090 scores anywhere from ~11,430 to 12,489, the performance delta will increase substantially in favor of the RTX 5090 if we calculate using the lower RTX 4090 scores. For instance, using the
11,430 Speed Way score for the RTX 4090, the RTX 5090’s result is 18% better.
So, it is safe to say that the RTX 5090 could bring a close to 20% ray tracing improvement vs the RTX 4090.
All in all, if the pure rasterization performance of the RTX 5090 is less than 10% faster than the RTX 4090 as discussed above, it will undoubtedly put the $400 price increase in question. This small rasterization improvement would also explain why Nvidia leaned so heavily into DLSS 4 during the RTX 50 unveiling.
That said, we have to reserve judgments until third-party RTX 5090 reviews drop. Till then, take all RTX 5090 performance rumors with a giant grain of salt.
