NVIDIA GeForce RTX 4080 16 GB Gaming Performance & 3DMark Benchmarks Leak Out

The NVIDIA GeForce RTX 4080 16 GB graphics card will utilize a cut-down AD103-300 GPU configuration with 9,728 cores or 76 SMs enabled of the total 84 units whereas the previous configuration offered 80 SMs or 10,240 cores. While the full GPU comes packed with 64 MB of L2 cache and up to 224 ROPs, the RTX 4080 would end up with 48 MB of L2 cache and lower ROPs too due to its cut-down design. The card is expected to be based on the PG136/139-SKU360 PCB. The graphics card is said to offer a peak clock rate of 2505 MHz.

As for memory specs, the GeForce RTX 4080 features 16 GB GDDR6X capacities that will be adjusted at 22.5 Gbps speeds across a 256-bit bus interface. This will provide up to 720 GB/s of bandwidth. This is still a tad bit slower than the 760 GB/s bandwidth offered by the RTX 3080 since it comes with a 320-bit interface but a lowly 10 GB capacity. To compensate for the lower bandwidth, NVIDIA could be integrating a next-gen memory compression suite to make up for the 256-bit interface.

Starting with the synthetic benchmarks first, the NVIDIA GeForce RTX 4080 graphics card scores 28599 points in the 3DMark Time Spy (standard) benchmark. This is a 36% performance uplift vs the 3090 Ti, a 61% uplift over the RTX 3090, and around 20% slower than the RTX 4090 flagship.In the more intensive 3DMark Time Spy Extreme benchmark, the graphics card end up scoring 14178 points at stock and 15062 points when overclocked. This is 26-30% faster than the 3090 Ti, 60-65% faster than the RTX 3080, and 25-20% slower than the RTX 4090 graphics card.Finally, we have the 3DMark DXR Ray Tracing feature test where the graphics card scored 87.12 FPS. Here, the NVIDIA GeForce RTX 4080 16 GB graphics card ends up 47% faster than the 3090 Ti, 86% faster than the RTX 3080, and 39% slower than the RTX 4090 flagship.

Based on the leaked performance figures, it looks like the NVIDIA GeForce RTX 4080 at $1199 US will have a tough time competing against AMD‘s $999 US Radeon RX 7900 XTX or even the $899 RX 7900 XT graphics cards. The graphics card launches almost a month prior to AMD‘s release so we won‘t know for sure how the performance compares until mid of December.
