NVIDIA GeForce RTX 50 “Blackwell” gaming playing cards might be geared up with new crystals based mostly on the most recent structure. These embody GB202, GB203, GB205, GB206 and GB207. NVIDIA affords completely different variations of those GPU dies, every concentrating on a distinct product section, but it surely primarily targets the shopper and client segments.
Based on Kopite7kimi, it appears like NVIDIA will use the identical variety of GPCs as the prevailing Ada line:
- GB202 (follower of AD102) -> 12 GPC (8×2 SM)
- GB203 (AD103 follower) -> 7 GPC (6×2 SM)
- GB205 (AD104 follower) -> 5 GPC (TBD)
- GB206 (AD106 successor) -> 3 GPC (TBD)
It was beforehand reported that the NVIDIA GB203 GPU could be half of the GB202, so principally the GB202 was speculated to include two GB203 dies, however plainly is not the case. As well as, it’s also clarified that the current rumors about an RTX 5090 with a 448-bit bus interface might be potential. It was initially deliberate to have a 512-bit bus interface and as much as 32GB of GDDR7 reminiscence.
When it comes to variety of SMs, NVIDIA’s Ada Lovelace GPUs had 128 cores per module with two SMs. The flagship AD102 had a complete of 12 GPCs and 6×2 SMs per GPC, for a complete of 144 SM items. It appears like GB202 goes to supply greater SM items with 8×2 SM per GPC, permitting as much as 192 SM. It isn’t clear if NVIDIA will embody 128 or extra cores per SM for Blackwell, however for now it appears like every chip could have no less than the identical variety of GPCs as Ada.
It’s introduced that solely the entry stage GB207 is not going to have the identical variety of GPCs as its predecessor AD107. For now, solely the Blackwell GB202 and GB203 GPUs for the GeForce RTX 5090 and RTX 5080 are anticipated to launch this 12 months, whereas the GB205, GB206 and GB207 might be launched in 2025.
NVIDIA is unquestionably making ready its GeForce RTX 50 “Blackwell” GPUs, which ought to present a big improve in graphics efficiency for the fanatic section. The discharge of the primary premium playing cards is reportedly scheduled for the 4th quarter of 2024.
