Handbrake H264

Handbrake H264 sees the 24-thread Ryzen 9 doing well by competing nicely with a Core i5-13600K and Core i9-12900K, albeit at significantly lower power draw.

PBO overclocking actually pushes the Ryzen 9 7900 above the 7900X. This is realistically a reflection of BIOS and AGESA updates in our test data.

The Ryzen 7 7700 also does well in Handbrake H264, especially given its estimated price point. If this chip does come in a reasonable amount below the Core i5-13600K price point – which is currently £320 in the UK – it should be an appealing option.

Handbrake H265

H265 performance is strong on Zen 4, and that is why we see the Ryzen 9 7900 doing well be competing against the Core i7-13700K.

The Ryzen 7 7700 also closes the gap notably against the high-power Core i5-13600K in this test, too.

7-Zip Compression and Decompression

7-Zip compression performance has shown a sizable improvement on these new processors thanks to an AGESA and BIOS update on our test system. As such, the Ryzen 9 7900 appears better than the 7900X, which isn’t really the case.

It does highlight how competitive the 65W Ryzens are against their higher-powered competitors, though.

Decompression performance is excellent, with AMD’s Ryzen 9 comfortably outperforming the Core i7. While the Ryzen 7 competes effectively against the juicy Core i5.
