RAM for the Core Ultra 5 245K

The Core Ultra 5 245K uses DDR5. 32GB (2×16GB) DDR5-6400 or faster; this platform scales with memory speed more than most. Run two sticks: single-channel memory costs this chip a meaningful share of its gaming performance.

Signs the Core Ultra 5 245K is your bottleneck

With 14 cores and 14 threads, core count is not the problem; when the Core Ultra 5 245K limits a game it is single-thread speed and cache that matter.

In an overlay, a Core Ultra 5 245K bottleneck looks like GPU usage dropping below about 90% while one or two CPU threads stay pinned, especially in crowded scenes and at 1080p.

How to confirm it on your own PC: reading CPU and GPU usage correctly. Fixes: how to fix a CPU bottleneck.

Upgrade paths from the Core Ultra 5 245K

The cheapest meaningful step up on the same LGA1851 socket is the Core Ultra 9 285K (about 8% faster in games); the strongest drop-in option is the Core Ultra 9 285K.

Core Ultra 9 285K — about 8% faster in games, $400–600 class.

Core Ultra 5 245K bottleneck FAQ

Does the Core Ultra 5 245K bottleneck the RTX 5090?

At 1080p the Core Ultra 5 245K is a severe limiter (45%). The RTX 5090 spends most of its time waiting, and frame pacing will suffer in CPU-heavy scenes. At 1440p the Core Ultra 5 245K is the limiter by a small margin (14%). The RTX 5090 has a little headroom, which mostly shows up as slightly lower 1% lows rather than a lower average.

What is the best GPU for the Core Ultra 5 245K at 1440p?

In our model the RX 9070 is the best-value match at 1440p ($400–600 class): At 1440p the RX 9070 is clearly the limiter (34% GPU-bound). That is fine as long as 127 fps meets your target; if not, the graphics card is the part to upgrade. Other balanced options at 1440p include the RTX 4090.

Is the Core Ultra 5 245K still good for gaming in 2026?

Yes. The Core Ultra 5 245K is a current high-end part: it keeps up with any graphics card at 1440p and 4K, and only the very fastest cards at 1080p can expose it.

Will faster RAM help the Core Ultra 5 245K?

What should I upgrade to from the Core Ultra 5 245K?

The cheapest meaningful step up on the same LGA1851 socket is the Core Ultra 9 285K (about 8% faster in games); the strongest drop-in option is the Core Ultra 9 285K.
