At the same price, this gaming test buries the Core Ultra 7 270K Plus against the 7800X3D

The Core Ultra 7 270K Plus has only just been released, and already a question arises: compared to the Ryzen 7 7800X3D, does Intel’s CPU hold up in online games? A comparative test published by the Chinese site Expreview provides a clear answer, and it is not flattering for Intel.

A comparison focused on real network usage

During our launch test of the Core Ultra 7 270K Plus, we observed a clear improvement in gaming performance, even if the processor remained generally behind AMD’s X3D models.

Expreview took the analysis further by comparing the two CPUs exclusively in this area, with an RTX 5090 configuration at 1080p to eliminate any GPU bottleneck. Two memory configurations were tested: DDR5-8000 in dual channel, and DDR5-6000 in single channel, the latter scenario being particularly relevant in the current context of soaring RAM prices.

On paper, the 270K Plus has good arguments: 8P+16E for 24 threads, boost to 5.5 GHz, 36 MB of L3, and memory support up to DDR5-7200. Opposite it, the 7800X3D displays more modest frequencies (5.0 GHz max), but has 96 MB of L3 cache thanks to 3D V-Cache technology. Both CPUs are offered at the same price.

Config de test

• The memory is not the same between the two platforms: DDR5-8000 dual channel for Intel, DDR5-6000 single channel for AMD on the degraded scenario
• RTX 5090 deliberately chosen to eliminate the GPU bottleneck
• Résolution 1080p, tout au max, raytracing désactivé

The results: 4-1-2 in favor of AMD

Out of seven online games tested, the 7800X3D won in four titles, tied in two, and lost in only one.

The 1% low is systematically in favor of the 7800X3D, which translates concretely into a smoother experience and less micro-jutters.

The single-channel révèle l’écart réel

It is the single channel test which is the most revealing. With a single DDR5-6000 strip, the 270K Plus shows significant drops: around twenty frames lost on LoL, a notable drop on Marvel Rivals. The 7800X3D absorbs the blow without flinching: its performance remains almost identical to dual channel on most titles.

The explanation is simple: the 7800X3D’s massive L3 cache acts as a buffer that reduces direct access to system memory. Less dependent on RAM bandwidth, it maintains a very high performance floor even in a sub-optimal configuration.

This is a concrete point for French buyers today: with the prices of DDR5 kits having increased significantly in recent months, many are considering starting with a single strip. In this scenario, the advantage of the 7800X3D widens even further.

Conclusion

The Core Ultra 7 270K Plus is a good all-around CPU, and its improvements over the basic Arrow Lake are real. But in the specific area of ​​online games, it cannot beat the 7800X3D. 3D V-Cache remains a technology without equivalent at Intel, and as long as Intel does not offer a direct answer, the 7800X3D retains its crown in this segment. At the same budget, for online gaming-oriented use, the choice remains AMD.
