NVIDIA's next-gen GeForce RTX 50 GPUs, including the RTX 5090 and RTX 5080, received slight TBP updates before their unveiling at CES.
NVIDIA GeForce RTX 50 "Blackwell" Enthusiast GPU Update: RTX 5090 At 575W & RTX 5080 At 360W
The NVIDIA GeForce RTX 5090 & RTX 5080 GPUs will be among the high-end launches within the Blackwell family that debut next week at CES 2025. These GPUs have seen specs leak over the past several months, but now, we have a slight update that comes from Kopite7kimi and Hongxing2020.
And RTX 5080 360W.

Previously, the NVIDIA GeForce RTX 5090 was expected to feature a TBP of up to 600W while the GeForce RTX 5080 was expected to feature a TBP of 400W, but now these figures are lowered and finalized. The higher TBP values might still be seen on custom models, but at least the reference models will feature lower TBP figures, so let's start with the specifications.
NVIDIA GeForce RTX 5090 32 GB Graphics Card
Starting with the details, we first have the NVIDIA GeForce RTX 5090, which is going to be the top GPU of the lineup. The graphics card is expected to feature the PG144/145-SKU30 PCB design and that's going to incorporate the GB202-300-A1 GPU core. The GPU will have 170 SMs enabled out of the total of 192 SMs and will feature 21,760 cores instead of the total of 24,576 cores. This marks an 11.4% reduction, which is slightly more than the -11.1% reduction of the RTX 4090 versus its full AD102 die.
On the memory side, the NVIDIA GeForce RTX 5090 is going to be a beast with 32 GB of GDDR7 VRAM capacity running across a 512-bit interface. The VRAM will operate at 28 Gbps speeds for up to 1792 GB/s of bandwidth plus a bigger L3 cache and new memory compression techniques are also going to boost the overall bandwidth available to the GPU.
The card will come with a 575W TBP rating, though it should be mentioned that the TBP value shouldn't be compared with actual real-world or gaming power consumption as that ends up much lower. Previous leaks have suggested a 2-slot cooler for the Founders Edition model of the RTX 5090. The PCB of the RTX 5090 has already been leaked and is shown to be very dense with a 16+6+7 phase layout, and a new 14-layer design with a backdrill process.
NVIDIA GeForce RTX 5080 16 GB Graphics Card
The NVIDIA GeForce RTX 5080 graphics card will be based on the PG144/147-SKU45 PCB and will incorporate the GB203-400-A1 GPU die. This card will utilize the full GB203 GPU die with 84 SMs and 10,752 cores, but that's a big -51% reduction compared to the RTX 5090. For comparison, the RTX 4090 and RTX 4080 had a -40 percent difference in the number of cores, so the overall performance is going to vary by a huge margin.
Other than that, the RTX 5080 is also going to feature half the VRAM configuration with a 16 GB capacity running across a 256-bit bus interface while utilizing GDDR7 modules. The graphics card will feature the fastest GDDR7 memory on the market, offering up to 32 Gbps speeds for 1024 GB/s or 1 TB/s of total bandwidth. The graphics card will feature a 360W TBP. This will be a 12.5% increase in the power wall versus the 320W of the RTX 4080 SUPER, but once again, the real-world figures should be very different.
The NVIDIA GeForce RTX 5090 and RTX 5080 will be the fastest GPUs in the lineup and will launch either by the end of January or early February. Expect more information on the next-gen lineup at CES 2025, which is a few weeks away.
