1，The Nvidia GeForce RTX 5090 release date is predicted to be in 2025, as part of the wider launch of its GPU family.
2，The Nvidia GeForce RTX 5090 price is estimated to be between $1,699-$1,999, making it a match or more expensive than its predecessor, the GeForce RTX 4090.
3，Some rumormongers claim that the RTX 5090 will be at least 70% faster than the RTX 4090, but it’s unclear whether this is in synthetic benchmarks or real-world frame rates.
The RTX 5090 is projected to include 204 Streaming Multiprocessors (SMs), leading to a total core count of 26,112. It is expected to be equipped with 32Gbps GDDR7 memory, operating over a 384-bit bus. This configuration contrasts with earlier considerations of a 512-bit bus. The L2 cache is anticipated to be 96MB. The GPU's core architecture, referred to as the Blackwell "GB202" gaming die, is described to have a 12 Graphics Processing Clusters (GPCs) x 8 Texture Processing Clusters (TPCs) configuration.
Each TPC is expected to contain 2 SMs, each with 128 FP32 cores. This structure leads to a theoretical core count of 24,576 (192 SMs) for a fully enabled GB202 die. However, manufacturing efficiencies may necessitate disabling some SMs, reducing the expected core count to 24,046 or less. The RTX 5090's memory bandwidth is projected to be 1,536 GB/s, a considerable increase from the 1,008 GB/s of the RTX 4090. This improvement represents a 50% enhancement in memory throughput and approximately a 60% increase in shader density. The overall performance uplift is anticipated to be up to 2x or more compared to its predecessor.
大家新年好！别等5090了，这参数值国行大概率还是会被禁售，该买啥买啥，按照自己的实际需求买卡吧，物尽其用就好，不必追新求贵 |
