AMD Strix Point APU’s integrated graphics leaks: RDNA 3.5 architecture, 16 CUs
A leak from PerformanceDatabase, evidenced by a screenshot from HWINFO, reveals that AMD’s forthcoming Strix Point APU’s integrated graphics will be fortified with an enhanced RNDA 3.5 architecture. Moreover, it will boast 1024 stream processors and 16 rasterization processing units, marking an increment of 256 and 4 respectively, when juxtaposed with the Radeon 780M integrated graphics of the Ryzen 7 7840H. However, it warrants attention that due to the software’s suboptimal support for the test version of the processor, the showcased 512MB GDDR6 VRAM might not be an accurate representation.
Strix Point, crafted with TSMC’s 4nm process, commands a TDP of 45W. Its CPU component encompasses 4 high-performance cores grounded in the Zen 5 architecture and 8 efficiency cores rooted in the Zen 5c blueprint. Both categories endorse hyperthreading, a feature absent in Intel’s efficiency cores. Each performance core luxuriates in a dedicated 1MB of L2 cache, while the efficiency cores, grouped in quartets, collectively access 1MB of L2 cache. The L3 cache reserves a capacity of 8MB. Notably, this CPU also exhibits support for the AVX-512 instruction set.
Beyond “Strix Point,” whispers circulate of another AMD high-end APU, christened “Strix Point Halo,” which embraces a Chiplet design. It fragments into two sub-chips, echoing the design philosophy of current desktop processors. The distinction emerges in the IOD section, endowed with a mightier GPU. Allegedly, the CPU segment of Strix Point Halo can marshal up to 16 cores, while the GPU segment, grounded in the RDNA 3.5 architecture, might proffer as many as 40 CUs. The memory bandwidth could potentially escalate to 256 bits, consuming power between 25-120W. In terms of graphical prowess, it’s poised to rival certain NVIDIA mobile dedicated GPUs.
Anticipation is rife that AMD will unveil Strix Point in either the second or third quarter of 2024, with Strix Point Halo gracing the stage later that year.
