NVIDIA RTX 4080 Specs Leak Out: 9,728 Cores, 16GB GDDR6X Memory, 70% Faster than the RTX 3080, and 420W TDP [Rumor]

The specifications of NVIDIA’s upcoming RTX 4080 graphics card have been shared by Kopite7kimi. It looks like the defacto Lovelace gaming GPU will be a smidge slower than initially anticipated rocking 9,728 FP32 cores alongside 16GB of GDDR6X memory across a 256-bit bus. NVIDIA has disabled 1,024 FP32 cores or 8 SMs on the AD103 die, leaving room for an RTX 4080 Ti on the same possibly with a wider bus.

The GPU core will likely be running close to 3GHz with the memory clocks set to 21Gbps. The RTX 4080 is expected to score 15,000 points in 3DMark TimeSpy Extreme, putting it approximately 70% faster than the RTX 3080. It will have a TGP of 420W, exactly 100W more than its predecessor. It’s worth noting that the RTX 3080 features 8,704 shaders and a 320-bit bus alongside a 10GB GDDR6X memory buffer, so most of the performance gains this generation are coming from the increased IPC, clocks, and cache (and power!). The RTX 4080 is slated to feature as much as 48MB of L2 cache.
