While exhaustive technical specifics of this GPU iteration remain undisclosed, certain indicators suggest an upgrade aligning with AD102 standards and a targeted Total Graphics Power (TGP) below 450W. For perspective, the RTX 4080, built on the AD103 GPU, has 9728 CUDA cores, not exploiting the GPU's maximum capacity of 10240 cores. This indicates Nvidia's strategy to narrow the performance disparity observed between the 9728-core RTX 4080 and the 16384-core RTX 4090.
MegasizeGPU stresses the significance of maintaining the TGP under 450W, a threshold below the RTX 4090. Nevertheless, the anticipated power draw could surpass the RTX 4080's 320W. While the precise CUDA core count remains unknown, projections place it between 9728 and 16384 cores, aligning with the specifications of the RTX 4080 and 4090. Additional specifications have yet to be revealed, but there's conjecture that the GPU might incorporate a memory capacity bridging the gap between the RTX 4080 and 4090, potentially accommodating 20GB of GDDR6x memory on a 320-bit memory bus.
It's pertinent to mention that although the RTX 4080's power consumption, currently benchmarked at 320W, could see an upswing, the magnitude hinges on as-yet-unspecified memory details. A potential RTX 4080 Ti might support 20GB of GDDR6X memory, situating itself between the 24GB and 16GB variants of the 4090 and 4080, respectively, necessitating a 320-bit memory bus. The industry insider suggests that the revamped RTX 4080 will likely be priced comparably to its predecessor, which was introduced at a recommended retail price of 1,469 euros. While MegasizeGPU hasn't provided conclusive confirmation regarding the specific variant, Nvidia's trend of phasing out 'Super' versions of GPUs implies a higher likelihood for the RTX 4080 Ti release.
With a launch timeline set for early 2024, there's ongoing speculation surrounding Nvidia's introduction of versions like the RTX 4090 Ti or RTX 4080 Ti, given that the existing non-Ti models don't maximize the ADA silicon's capabilities. The upcoming RTX 4080 variant could possibly maintain the existing RTX 4080's price tag of $1,199, implying a potential price revision for the original RTX 4080.
