Intel Core Ultra 5 338H Review

The Intel Core Ultra 5 338H is the oddball of the Panther Lake lineup: nominally a Core Ultra 5, but built with a 12-core CPU and a 10-Xe3-core Arc B370 iGPU, graphics capability that would normally justify an X-series badge. Reviewers covering the launch specifically flagged this as an unusual naming decision, since the 338H's graphics horsepower sits much closer to the X7/X9 tier than to the rest of the Ultra 5 family it's officially grouped with.

Intel Arc B370 (10 Xe3-cores)

A near-flagship iGPU configuration, just two Xe3-cores short of the full 12-core B390 found on the X7 and X9 chips, giving the 338H unusually strong integrated graphics for a chip carrying the Ultra 5 badge.

How Is the Core Ultra 5 338H in Terms of Performance

CPU-side, the 338H's 12-core count sits below the 16-core H-series and X-series chips, so multi-threaded workloads won't match those higher tiers. Graphically, however, the 10-core Arc B370 punches well above its price and naming tier, making this chip a genuinely strong pick specifically for buyers prioritising integrated graphics performance over raw CPU throughput at a lower price point than the X-series commands.

Benchmarks

Expect Geekbench 6 multi-core scores below the 16-core H-series and X-series chips given the reduced core count, but integrated graphics benchmarks and light gaming tests should place the 338H well ahead of other Core Ultra 5 SKUs and closer to the X7/X9 tier than its own product name suggests.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Thin laptops without a discrete GPU, using the 10 Xe3-core Arc B370 integrated graphics
Everyday and AI work with 12 cores and a 50 TOPS NPU

Not for

Buyers needing 16 cores, since this chip has 12 cores and 12 threads
Laptops requiring DDR5 SO-DIMMs, as this chip is listed for LPDDR5x
