Published Benchmarks

These are still limited and lack real world application benchmarks for creative professionals.

Geekbench CPU Multi-Core

  • i9-12900K - 17201
  • M1 Ultra - 24000 (96% scaling)
  • M1 Max- 12500
In raw CPU performance the M1 Ultra is about 50% faster than the i9-12900K, which may not perform optimally in real world applications due to the lack of support for P and E cores in macOS.

Geekbench CPU Single-Core

  • i9-12900K - 1996
  • M1 Ultra - 1790
  • M1 Max - 1780

Geekbench GPU Metal

Geekbench GPU OpenCl

Benchmarks and scaling

The M1 scales almost linearly with doubling the CPU core count from M1 Max to M1 Ultra (96%), but the GPU does not scale quite as well, as the increase in performance is only 80% when doubling the GPU cores. This puts the 48 core version closer to a RX 6600 XT and the 64 core version at only two-thirds of the Metal performance of the RX 6900 XT.
  • Barefeats: M1 Max 16 versus Intel 16 The M1 Max does perform better in real world benchmarks than the raw Geekbench Metal scores suggest. With 80% scaling, the M1 Ultra with 64 cores should therefore be able to outperform the RX 6900 XT in some important applications.

Proposed Alder Lake SFF Hardware for a Hack Studio Ultra

Liquid Cooler in SFF Case

  • hoses should face upward and pump should not be too big pump due to cramped ITX board
  • use shorter hoses (380 mm, over PSU), rather than over memory and under PSU
AIO Compatibility with Lian Li DAN A4-H20
An i7-12700 might be more suitable for this case with a 240 mm cooler. - If the cooling capacity inside the Lian Li DAN A4-H20 proves to be insufficient for the i9-12900K, a case like the 15 liter Meshlicious could be used instead, as it can accommodate a bigger 280 mm liquid cooler and has more space for the GPU. (Dimensions:42 cm x 22 cm x 31 cm)
