The NVIDIA GeForce RTX 4090 will use 128 SMs of the 144 SMs for a total of 16,384 CUDA cores. The GPU will come packed with 96 MB of L2 cache and a total of 384 ROPs which is simply insane but considering that the RTX 4090 is a cut-down design, it may feature slightly lower L2 and ROP counts. The clock speeds are not confirmed yet but considering that the TSMC 4N process is being used. The clock speeds are rated at up to 2.6 GHz and NVIDIA is claiming over 3 GHz speeds with overclocking which you can read more about here.
As for memory specs, the GeForce RTX 4090 will feature 24 GB GDDR6X capacities that will be clocked at 21 Gbps speeds across a 384-bit bus interface. This will provide up to 1 TB/s of bandwidth. This is the same bandwidth as the existing RTX 3090 Ti graphics card and as far as the power consumption is concerned, the TBP is rated at 450W. The card will be powered by a single 16-pin connector which delivers up to 600W of power. Custom models will be offering higher TBP targets.
NVIDIA GeForce RTX 4090 Graphics Cards Performance
As for the performance of these monster GPUs, NVIDIA shared the computational and gaming performance figures and it looks like the GeForce RTX 4090 will be the first gaming card to hit the 100 TFLOPs compute horsepower limit.
Just for comparison’s sake:
NVIDIA GeForce RTX 4090: 90 TFLOPs (FP32) (Assuming 2.8 GHz clock)
NVIDIA GeForce RTX 3090 Ti: 40 TFLOPs (FP32) (1.86 GHz Boost clock)
NVIDIA GeForce RTX 3090: 36 TFLOPs (FP32) (1.69 GHz Boost clock)
Based on a theoretical clock speed of 2.8 GHz, you get up to 103 TFLOPs of compute performance and the rumors are suggesting even higher boost clocks. Now, these are definitely sounding like peak clocks, similar to AMD’s peak frequencies which are higher than the average ‘Game’ clock. A 100+ TFLOPs compute performance means more than double the horsepower versus the 3090 Ti flagship. One should remember that compute performance doesn’t necessarily indicate the overall gaming performance. Even so, it will be a huge upgrade for gaming PCs and an 8.5x increase over the current fastest console, the Xbox Series X.
FP32 Compute Horsepower Comparisons (Higher is Better)
This will be a 2x compute performance uplift and a 2x gain in gaming performance as NVIDIA has demonstrated for each graphics card versus its predecessor and this is without even factoring in the RT and Tensor core performance which are expected to get major lifts too in their respective department. A 2-4x gain over the RTX 3090 & RTX 3090 Ti would be very disruptive.
Gamers should expect 4K gaming to be buttery smooth on these graphics cards and with DLSS, we might even see playable 60 FPS at 8K resolution which is something that NVIDIA has been trying to achieve with its RTX 3090 series BFGPUs for a while now.
NVIDIA GeForce RTX 4090 Graphics Cards Price & Availability
Now coming to the prices, the NVIDIA GeForce RTX 3090 Ti & RTX 3090 graphics cards are undoubtedly the most expensive single-chip GPUs to date. The NVIDIA GeForce RTX 4090 will come at a price of $1599 US for the Founders Edition variant and custom models starting today.
