Surface Laptop 4: Microsoft tests AMD Ryzen and Intel Tiger Lake


Two current results from Microsoft’s Surface Laptop 4 appeared in the Geekbench benchmark database. Accordingly, the company is testing notebooks with both AMD and Intel processors – the Surface Laptop 3 already appeared with models from both chip manufacturers.

According to the first Geekbench result Tiger Lake U processors (Core i-1100G) from Intel are used in some versions. The database specifically names the Core i5-1135G7 with four CPU cores, eight threads and an integrated Xe graphics unit. For the Intel versions of the Surface Laptop 3, Microsoft relied on the Ice Lake U models Core i7-1065G7 and Core i5-1035G7. The successors are faster per CPU core and support Thunderbolt 4 instead of 3.

Microsoft apparently uses Zen 2 technology in at least one AMD version. Geekbench read Renoir, the code name for Ryzen 4000U. This is matched by the two 4 MB level 2 cache. The specified AMD Ryzen 5 3580U Microsoft Surface Edition model is likely to be a bug: The processor was used in the Surface Laptop 3, uses only four instead of the specified six CPU cores and has half as much L3 cache.

The use of Lucienne processors, the new edition by Renoir within the Ryzen 5000U series, would also be conceivable. It continues to rely on Zen 2 cores, but comes with improvements that are supposed to increase efficiency. The real Renoir successor Cezanne with a faster Zen 3 architecture uses 16 MB L3 cache – a read error seems unlikely.

Microsoft traditionally brings out new hardware along with feature updates for Windows 10. The 21H1 update is already in the starting blocks, so an announcement of the Surface Laptop 4 seems conceivable within the coming weeks.
