We will be pitting the new 65W TDP Ryzen 7000 series non-X chips against their logical Ryzen 7000, Ryzen 5000 and Intel 12^th and 13^th Gen competitors.

The AM4-based Ryzen 5000 processors will be coupled with 32GB of dual-rank DDR4 3600MHz C16 memory. Both DDR5 platforms use 32GB 6000MHz sets from G.SKILL’s Trident Z5 range. Though the timings differ slightly, with the AMD EXPO kit running at 30-38-38-96 versus the Intel XMP set at 36-36-36-96. This is pretty close between the two sets.

The new AMD processors are tested on Gigabyte’s X670E Aorus Master motherboard featuring the BIOS revision and AGESA profile as supplied and validated by AMD.

Each processor is tested at its default out-of-the-box settings. For the Intel CPUs, turbo limits as set by the motherboard with XMP enabled is the operating mode. All-core load frequencies for the tested chips are as follows:

• Core i5-12600K = 4.5GHz on the P-cores.
• Core i7-12700K = 4.7GHz on the P-cores.
  
• Core i9-12900K = 4.9GHz on the P-cores.
• Core i5-13600K (168W) = 5.3GHz on the P-cores.
• Core i7-13700K (253W) = 5.3GHz P-cores.
• Core i9-13900K (253W) = 5.5GHz on the P-cores.
• Ryzen 5 5600X = around 4.3GHz.
• Ryzen 7 5800X = around 4.56GHz.
• Ryzen 7 5800X3D = around 4.4GHz.
• Ryzen 9 5900X = around 4.25GHz.
• Ryzen 9 5950X = around 3.85GHz.
• Ryzen 5 7600X = around 5.2GHz.
• Ryzen 7 7700X = around 5.18GHz.
• Ryzen 9 7900X = around 5.1GHz.
• Ryzen 9 7950X = around 5.05GHz.
