Nvidia GeForce RTX 5090 发布时间和参数预测 （别等了，国行大概率还是会被禁售）
本帖最后由 enolc 于 2024-1-2 02:01 编辑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[傻笑] 4090被禁售了吗？
我怎么看到那些店卖的欢的要死，反而4090d没几家在卖啊 大头吃小头 发表于 2024-1-2 02:02

现在卖的都是囤的货吧？ 最大的疑问是24G的显存改不改？ 按照商务部的说法 4090D 也就几个月寿命也同样要被禁售，简单来说就是说不定 5070 Ti 以上的都是 X 大头吃小头 发表于 2024-1-2 02:02

现在卖的都是囤货和抢在限售令生效之前就运到保税区的货。 怕啥至少下一代 5070or80还是有4090D的性能的功耗更低 至于以后的 美国佬都不知道以后总统是谁呢 tim6252 发表于 2024-1-2 07:16

脱钩断链是大趋势，谁当总统、谁当议长都一样。
以后只有溢价水货。 本帖最后由 Flanker 于 2024-1-2 08:06 编辑
先不说gb202的规格对不对，光是拿完整gb202的规格当5090的规格就还活在梦里
表格下面那段话更是胡言乱语[困惑] 关心一年后的卡干嘛 活在当下 人生苦短 及时行乐
512bit。。。还能再假一点吗[偷笑] enolc 发表于 2024-1-2 02:03

二修卡吧....不都拆出來做渦版了嗎[偷笑] 漂亮商务部这帮人能不能干到5090出来还一说呢，不过最根本上还是国产有替代，咱们自己可以炼丹了后，老黄可能还能重视一下游戏业务。 前事如烟 发表于 2024-1-2 08:15
512bit。。。还能再假一点吗
大概率是GDDR7，位宽不变。GDDR7如果难产，512bit也并非不可能，可能性很小就是了 禁售就买水货或者找人带吧 大佬 5090会上满血dp2.1接口吗 我觉得从商业角度上来看 下一代高端直接没竞争对手 老黄没必要上512bit 也不会给32G显存 甚至gddr6x继续清库存 常规提升一下 避免牙膏挤多了 还有一年多的时间，什么事情都可能发生。
