What’s Nvidia as much as with its next-generation GPU? Based on current leaks, the specs of the RTX 5090 are anticipated to depart every part that has come earlier than it behind by a major margin
With the discharge of the Geforce RTX 4090, graphics card producer Nvidia is operating lonely circles within the prime efficiency class of our GPU rating. This hole to its personal upper-class fashions and sure, additionally to AMD, is meant to be widened even additional by the upcoming flagship of the Blackwell
christened technology.
We’re in fact speaking concerning the Geforce RTX 5090 in addition to a possible Ti model, which remains to be lacking from the RTX 4090. Though it’s going to nonetheless take a while till a attainable launch – the speak is a few launch within the yr after subsequent – the rumor mill is already operating scorching, as a result of the well-known leaker kopite7kimi claims to have came upon concrete particulars concerning the RTX 5090.
Based on the leak, the Geforce RTX 5090 appears to step up a gear in virtually each specification.
Particularly, kipite7komi talks a few 12×8 construction of the GB202 chip that’s used within the flagship. This implies twelve GPCs (Graphics Processing Clusters) with eight TPCs (Texture Processing Clusters) every. With twelve streaming multiprocessors (SM) inside a GPC, nothing ought to change.
As I discussed earlier than, GA100 is 8*8, and GH100 is 8*9. GB100 may have a fundamental construction like 8*10. GB202 appears to be like like 12*8.

Now it will get technical for a second: If this leak is true, we will additionally deduce what number of CUDA cores are put in within the RTX 5090. A complete of 192 SMs of 64 FP32 and FP32/INT32 items every end result within the following equation:
Variety of CUDA cores = Variety of SMs * Variety of FP32 + Variety of SMs * Variety of FP32/INT32.
So, inserting the numbers from the rumor, we get that the RTX 5090 can fall again on 24,576 CUDA items – rising by just about precisely 50 p.c from the RTX 4090.
Based on the leak, Nvidia additionally needs to make a giant splash, not a small one, in relation to video reminiscence.
How a lot L2 cache and reminiscence bit bus?

Current rumors already say that the RTX 5090 has a GDDR7 reminiscence of 32 GBytes, which is meant to be related through a 512-bit interface in keeping with kopite7komi. The L2 cache is meant to extend to 128 MB.
So as to make clear the assumed efficiency leap between the RTX 4090 and RTX 5090 as soon as once more, you could find all related and supposed specs summarized within the following desk:
Geforce RTX 4090 (“Ada Lovelace”)
Geforce RTX 5090 (“Blackwell”)
Reminiscence measurement
24 GByte GDDR6X
32 GByte GDDR7
Reminiscence interface
384-bit
512-bit
L2 cache
72 MByte
128 MByte
Now, in fact, it’s conceivable that Nvidia will use a barely trimmed model for the RTX 5090’s GB202 processor, much like the RTX 4090’s AD102 chip.
Lastly, even the RTX 4090 doesn’t exhaust the theoretical most capacities of the AD102 chip, which is why a possible launch of an RTX 4090 Ti was thought-about doubtless for a very long time – till current leaks most likely shelved it totally.
As well as, it stays questionable why Nvidia ought to even totally make the most of the GB202 chip, as a result of as could be seen within the feedback beneath the leak in addition to in our GPU rating talked about originally, the present flagship is already operating out of competitors.
It solely stays to be seen whether or not AMD can one way or the other shut this hole with Radeon RX 8000 – it could actually be good for the competitors.
Now it’s your flip: What do you consider the RTX 5090 leaks? Would these specs lastly cement Nvidia because the frontrunner within the high-end phase, or do you belief AMD to catch up? Tell us within the feedback!
