Recently, many digital hardware enthusiasts have been focusing on Intel and AMD’s new generation of desktop processors, comparing options for upgrades by the end of the year. However, some are also interested in NVIDIA’s upcoming RTX 50 series graphics cards, anticipating future upgrades.
Over the past six months, there have been numerous rumors about the RTX 50 series, but most are inconsistent and lack reliability. The following information comes from a well-known overseas hardware leaker, who has a solid track record of accurate leaks.
It is widely known that NVIDIA typically releases mid to high-end models first. The leaker, kopite7kimi, has primarily focused on the GeForce RTX 5090 and RTX 5080.
For the GeForce RTX 5090, there has been an “exciting” rumor suggesting it will have a 512-bit bus width and 32GB of GDDR7 memory. In comparison, the flagship models RTX 3090 and RTX 4090 both have a 384-bit bus width and 24GB of GDDR6X memory, marking a significant upgrade for the RTX 5090.
However, this rumor faced a quick reversal, with other leakers claiming the RTX 5090 will have a 448-bit bus width instead of 512-bit, causing confusion. Additionally, another widely discussed rumor indicated that the RTX 5090’s TDP would increase to 600W. For reference, the RTX 3090 has a TDP of 350W and the RTX 4090 has 450W, making the 600W claim quite substantial, though lacking reliable sources for confirmation.
So, does kopite7kimi’s latest leak support these rumors? The answer is largely affirmative. The GeForce RTX 5090 is expected to feature a GB202-300 GPU based on the Blackwell architecture, with 21,760 CUDA cores and 170 streaming multiprocessors. It will have a 512-bit bus width, 32GB of GDDR7 memory, a memory speed of 28 Gbps, and a memory bandwidth of 1972GB/s. Other parameters, such as raster units and texture units, remain unknown.
In comparison, the GeForce RTX 4090 utilizes an AD 102-300 GPU based on the Ada Lovelace architecture, with 16,384 CUDA cores, 128 streaming multiprocessors, a 384-bit bus width, 24GB of GDDR6X memory, a memory speed of 21 Gbps, and a memory bandwidth of 1008GB/s.
As for the RTX 5090’s TGP, kopite7kimi aligns with the earlier rumor of 600W.
In addition to the RTX 5090, the leaker also mentioned the mid-range GeForce RTX 5080:
The RTX 5080 is expected to feature a GB203-400-A1 GPU based on the Blackwell architecture, with 10,752 CUDA cores, 84 streaming multiprocessors, a 256-bit bus width, 16GB of GDDR7 memory, a memory speed of 28 Gbps, and a bandwidth of 896GB/s, with a power consumption of 400W.
For comparison, the RTX 4080 has an AD103-300 GPU based on the Ada Lovelace architecture, with 9,728 CUDA cores, 76 streaming multiprocessors, a 256-bit bus width, 16GB of GDDR6X memory, a memory speed of 22.4 Gbps, and a bandwidth of 717GB/s, with a power consumption of 320W.
Overall, if kopite7kimi’s leaks are accurate, the GeForce RTX 5090 shows significant improvements over the RTX 4090, while the RTX 5080 has more limited enhancements compared to its predecessor.
Regarding the release date for the RTX 50 series, kopite7kimi did not specify in the latest leak, and there are currently no reliable rumors. However, it is generally expected to be launched between late 2024 and early 2025.
