TECH NEWS – AMD’s technology may finally have some competition with a new processor and sufficiently powerful integrated graphics.
Panther Lake’s cost-effective product has appeared on Geekbench, showcasing an integrated graphics processor (iGPU) performance that is roughly on par with AMD’s Radeon 880M. With the debut of Intel Panther Lake expected in a few months, more and more test result leaks are appearing. The latest is the Core Ultra 5 338H, one of the slowest in the PTL-H series. It appeared on Geekbench, confirming its specifications. The results page shows that the Ultra 5 338H has two core clusters, or 4+8 cores.
However, these are P cores (4), E cores (4), and LP-E cores (4). The base clock speed is 1.9 GHz, but the boost clock speed is close to 3.7 GHz. This seems low compared to the 4.8 GHz boost clock speed of the Core Ultra X7 358H according to leaked information. The boost clock speed is expected to be closer to that of the X7 358H, possibly reaching 4.7 GHz. Other specifications are also listed, such as the cache size. The Core Ultra 5 338H has 3 MB of L2 cache and 18 MB of L3 cache.
The most interesting part is the integrated GPU, rumored to have 10 Xe3 cores. The model name here is Arc B370. In the previous leak, however, the model name of the Core Ultra X7 358H iGPU was not mentioned. The Arc B370 scored 39,406 points on Geekbench’s Vulkan test. In terms of performance, it rivals the AMD Radeon 880M found in the AMD Strix Point APU (also known as the Ryzen AI 9 365), which uses RDNA 3.5 architecture for the iGPU. Although Geekbench results can vary greatly from test to test, it seems that we can expect decent iGPU performance from Panther Lake chips. Earlier, we saw that the Core Ultra X7 358H’s 12 Xe3-core-based iGPU was in close competition with the laptop RTX 3050. In the Geekbench OpenCL test, the iGPU even easily beat the Radeon 890M.
Therefore, the Arc B370’s performance will be equivalent to or better than the Radeon 880M.
