兄台听谁说的33t？ps5只有10t，gpu面积增大67%这里面还得有负责光追部分，也就是说实际gpu增加不过是40%多 ...

Upgraded GPU: With PS5 Pro, we are upgrading to a GPU that has 67% more Compute Units than the current PS5 console and 28% faster memory. Overall, this enables up to 45% faster rendering for gameplay, making the experience much smoother.
Advanced Ray Tracing: We’ve added even more powerful ray tracing that provides more dynamic reflection and refraction of light. This allows the rays to be cast at double, and at times triple, the speeds of the current PS5 console.
AI-Driven Upscaling: We’re also introducing PlayStation Spectral Super Resolution, an AI-driven upscaling that uses a machine learning-based technology to provide super sharp image clarity by adding an extraordinary amount of detail.

想告诉啥？33t？这里说了gpu提升67%，所以能从10t变33？还是你说的那个什么pssr，能增加出20t的算力？

67%是CU数量增加，可不是GPU面积

RDNA3开始因为是双发射所以计算的浮点性能直接翻倍，所以8400U号称有8.4Tflops，60CU的7700XT跑PS5目前的频率算出来就有33Tflops，这是AMD自己给的公式，问题要有也是AMD的，索尼倒是很老实说了计算速度增加45%

绝了，rdna3浮点注水都多久了，a9还能争起来，只有老哥你道出真相

看来a9真就没几个人玩pc

有些人为了黑而黑怎么会有脑容量去了解下这个结果是怎么来的

索尼都不敢你这么吹

安息不二

确实不懂这些，不过看样子吹浮点比数毛强多了，这不一下子翻三倍显得多200刀贼划算

实际情况就是ps5现在开到pc中画质跑三十帧变成ps5Pro跑四十多帧！然后pssr算法插帧到60。。要么插值分辨率。。就这么回事了。看发布会演示也是如此画质没什么提升的情况下提升帧数跑个六十帧。
