NVIDIA’s next-gen GeForce RTX 4080/4090 GPUs are now being tested and evaluated, indicating that early engineering/production samples have already reached Santa Clara. According to the source (below), the AD102 GPU core is now being tested internally for early performance and specification targets. This means that we should soon start seeing leaks and benchmarks of these engineering samples, giving us a first glance at NVIDIA’s upcoming graphics architecture.
The GeForce RTX 4090 is going to come with 24GB of 24Gbps GDDR6X memory paired with 96MB of L2 cache across a 384-bit bus. The RTX 4080 is expected to feature 12 or 16GB of GDDR6X memory across a 320-bit bus and 80-88MB of L2 cache. This GPU will feature around 14,000 FP32 cores, a slight cut from the 15-16K shaders on the RTX 4090, and a total of 18,432 on the AD102 die. As for the RTX 4070, we’re looking at 12 or 16GB of GDDR6 memory across a 256-bit bus. It will be based on the AD104-400 die and pack up to 10,000 FP32 cores.
