the power of an RTX 4070 in the iGPU?

Before starting, let us specify that this information comes from a leak and should therefore be taken with a grain of salt. Indeed, he begins to say to himself at the youtubeur Moore’s Law is Dead that the next iGPU processors AMD Ryzen 8000 Mobile would be endowed with great power at the level of a RTX 4070 Mobile from NVIDIA. Such power for an iGPU represents a colossal performance voucher and that is why we must remain cautious.

A future without dedicated GPU for laptops?

Known as Strix Point, Strix Halo/Starlake et Fire Rangethese next APUs AMD (this term corresponds better to these processors than just “CPU”) will run under the architecture AMD Zen 5 and the graphic part will be under RDNA 3.5. We therefore remain roughly under RDNA 3, but with a reworking of the architecture. Incidentally, high-end APUs codenamed Strix Halo (oh the pretty name that brings to mind a product from ASUS ROG) will have a maximum of 16 cores and 32 threads. Note that according to the RedGamingTech media, these processors could present an IPC gain of around +25% compared to Ryzen 7000 processors.

Going back to MLID’s statements, the top-end Ryzen 8000 iGPU could have 40 CUs and 2560 stream processors with 32MB of Infinity cache. These characteristics would make it able to compete against an RTX 4070 Mobile graphics card with a consumption of 95W. The other variants of the iGPU meanwhile would have 2048 stream processors and would be similar to an RTX 4050 Mobile and the latest version would be at 1280 stream processors for operation comparable to the RTX 3050.

With such powers, the next laptops intended for players in the mid-range sector could even completely do without a dedicated GPU with lower energy consumption, but also more easily controllable temperatures. We would therefore also gain in weight and bulk. All this is reminiscent of Apple, which is beginning to integrate everything into a single chip. This reduces costs and requirements.
