原英文标题：《AMD RDNA3 GPUs get new toned down specifications, Navi 31 with up to 12288 Stream Processors》
Rumored specs of RDNA3 architecture has changed
传闻中的RDNA3架构规格已更改
According to Greymon55, the internal structure of the Navi 3X GPUs might be different from previously reported.
根据Greymon55的说法，Navi 3X GPU的内部结构可能与之前报道的不同。

Not 15360 Stream Processor but 12288 for Navi 31 GPU, the flagship processor of the upcoming RDNA3 series. This means that the 92 TFLOPS claim from a few days ago is either wrong, or there is something else that we do not know about yet.
不是15360流处理器，而是12288用于Navi 31 GPU，这是即将推出的RDNA3系列的旗舰处理器。这意味着几天前92 TFLOPS的声明要么是错误的，要么还有其他我们还不知道的事情。
The Navi 31 with 6 Shader Engines, 12 Shader Arrays and 48 Work Group Processors would ship with up to 12288 Stream Processors, that’s a reduction of 20% in core count compared to previously rumored 15360 cores. The same applies to Navi 32, which instead of 10240 cores would ship with 8192 Stream Processors. For the Navi 31 this means 4096 cores instead of 5192, but it should be noted that lower core count was mentioned by Greymon55 before.
配备 6 个着色器引擎、12 个着色器阵列和 48 个工作组处理器的 Navi 31 将配备多达 12288 个流处理器，与之前传闻的 15360 个内核相比，核心数量减少了 20%。这同样适用于Navi 32，它将配备8192个流处理器，而不是10240个内核。对于Navi 31，这意味着4096个核心而不是5192个，但应该注意的是，Greymon55之前提到过较低的核心数量。
AMD Navi III (RDNA 3)
Navi 31: 12288 SPs, 48 WGPs, 12 SAs, 6 SEs
Navi 32: 8192 SPs, 32 WGPs, 8 SAs, 4 SEs
Navi 33: 4096 SPs, 16 WGPs, 4 SAs, 2 SEs https://t.co/h46ytpdifo

With the updated Navi 31 specs, the rumored TFLOPS would drop to 73 TFLOPS, and that’s assuming 3.0 GHz GPU clock. We still do not have any leaks or rumors on the Navi 32 and 33 clocks speeds, though.
随着Navi 31规格的更新，传闻中的TFLOPS将降至73 TFLOPS，这是假设3.0 GHz GPU时钟。不过，我们仍然没有关于Navi 32和33时钟速度的任何泄漏或谣言。
Navi 31 old → new spec
60 WGP, 15'360 FP32 → 48 WGP, 12'288 FP32
on 3 GHz = 73 TFlops
Navi 32 old → new spec
40 WGP, 10'240 FP32 → 32 WGP, 8'192 FP32
Navi 33 remains the same (16 WGP, 4096 FP32).

One should remember that we are still months away from the launch of new 3rd Gen Navi GPUs. This is, however, the first major update to the rumored specs that have been shared for more than a year. So unless there are other reliable sources claiming otherwise, we will assume that those specs are closer to final.
人们应该记住，我们距离推出新的第三代Navi GPU还有几个月的时间。然而，这是对已经共享了一年多的传闻规格的第一次重大更新。因此，除非有其他可靠的消息来源另有说法，否则我们将假设这些规格更接近最终版本。
