Intel’s Tiger Lake-H processors may just beat AMD’s Cezanne lineup, but it looks like that victory won’t last long. According to info shared by ExecutableFix on Twitter, the successor to Cezanne, Rembrandt will increase its integrated graphics performance by quite a bit: 60% at the very least, and twice as much in ideal scenarios compared to the Renoir/Cezanne APUs.
Rembrandt is slated to launch for consumer notebooks in the first half of 2022 (most likely at CES 2022). These mobile processors will retain the Zen 3 core, but upgrade the integrated graphics from Vega to RDNA 2 with 50% more CUs (8 CUs or 512 shaders to 12 CUs or 768 shaders). Furthermore, since we’re looking at an enhanced variant of the 7nm node with EUV lithography, these APUs will be clocked a bit higher than Cezanne/Renoir. RDNA is already a high-clock speed/high IPC architecture, and when paired with TSMC’s 6nm node, we might just see clock speeds as high as 2GHz on an onboard GPU solution. An increase of 50% in sheer compute capabilities, higher clock speeds, and an IPC gain of 20-25% should allow for a doubling of overall graphics performance compared to existing Vega iGPUs.
Before Rembrandt, we should see the Van Gogh processors launch for ultra-low-power and embedded systems in the 3rd quarter of the year. Van Gogh will retain the Zen 2 core but upgrade the GPU side to RDNA 2. It will be the first mobile SoC to move away from Vega and should give us an idea of how the architecture works in a low TDP form factor.
