    RTX 4080 has 9728 cores, 16GB GDDR6X memory, 420W TBP, 35% faster than RTX 3090 Ti




    Like yesterday’s RTX 4070 specswe now also have updated specifications for the NVIDIA GeForce RTX 4080 graphics card.

    The same insider, Kopite7kimi, has previously posted a slightly better core config for the RTX 4080, but it should be noted that NVIDIA makes several revision changes during the product launch cycle and so the specs change a lot, which Kopite7kimi is just reporting. The card now has the same number of cores and memory, albeit with a much lower TGP than previously reported.


    The NVIDIA GeForce RTX 4080 is expected to use a stripped-down AD103-300 GPU configuration with 9728 cores or 76 SMs out of 84, while the previous configuration offered 80 SMs or 10,240 cores. While the full GPU comes with 64MB L2 cache and up to 224 ROPs, the RTX 4080 can get 48MB L2 cache and lower ROPs due to its stripped-down design.

    Clock speeds are yet to be confirmed, but given that the TSMC 4N process is used, we expect clock speeds in the 2.0-3.0 GHz range. The higher-than-usual clock jump is due to NVIDIA making a two-node jump, given that Samsung’s 8nm-node Ampere GPUs were actually a 10nm process node with some optimizations. NVIDIA skips 7nm and immediately switches to the 5nm process technology, and not even a vanilla version, but an optimized version of it. With Pascal on TSMC’s 16nm node, NVIDIA has achieved a huge frequency jump, and we can expect the same jump this time around.

    In terms of memory specs, the GeForce RTX 4080 is expected to come with a 16GB GDDR6X capacity, which is said to be tuned for 21Gb/s through a 256-bit bus interface. This will provide throughput up to 672 GB / s. In terms of power, the TBP is rated at around 420W, which is close to the RTX 4090, and since the memory clocks aren’t as aggressive, it’s likely that the core clocks can be tweaked for maximum graphics performance.

    In terms of performance, the NVIDIA GeForce RTX 4080 is expected to offer 15,000 points in the 3DMark Time Spy test, which was previously stated as a conservative figure, so you can expect around a 35 percent performance boost over the RTX 3090 Ti in this particular test. .
