Two Mid-Range CPUs, One Resolution That Actually Matters
The AMD Ryzen 5 9600X and Intel Core Ultra 5 245K sit at the center of the mainstream desktop CPU market, both priced to attract serious PC builders who game at 1440p. At that resolution, the CPU starts to matter more than it does at 4K, where the GPU becomes the clear bottleneck. So the question is straightforward: which chip actually delivers better rasterized gaming performance when the monitor is running at 2560×1440?
What Each CPU Brings to the Table
The Ryzen 5 9600X is built on AMD’s Zen 5 architecture, featuring 6 cores and 12 threads with a boost clock that reaches 5.4GHz. It’s a compact, power-efficient design – TDP sits at 65W by default, though AMD’s PPT limits allow it to draw more under sustained loads. The chip slots into AM5 motherboards, the same socket AMD has committed to through at least 2027, which matters for anyone planning future upgrades.
Intel’s Core Ultra 5 245K takes a different structural approach. It uses a hybrid architecture with 6 Performance cores and 8 Efficient cores, for a total of 14 cores and 13 threads (P-cores are hyperthreaded, E-cores are not). The base power is 125W, which tells you something about Intel’s thermal expectations right away. It runs on LGA1851 and requires a 800-series motherboard, and while Intel has signaled this platform won’t be particularly long-lived, the 245K itself is a strong performer where raw throughput counts.
Both chips pair well with fast DDR5 memory, though the 9600X tends to show more scaling benefit from tight subtimings on DDR5-6000 in AMD’s EXPO sweet spot. The 245K responds well to XMP profiles on DDR5-6400 and above. For this comparison, both were tested with DDR5-6000 at CL30 to keep the memory variable as equal as reasonably possible, mounted on mid-range Z890 and X870 motherboards respectively.
The GPU used throughout testing was an RTX 4080 Super, chosen specifically to reduce GPU bottlenecking without eliminating it entirely at 1440p. A weaker GPU would mask CPU differences; a stronger one at 4K would do the same. If you want to see how these chips handle a heavier resolution load, the Ryzen 5 9600X vs Core Ultra 5 245K: 4K Gaming Tested breakdown covers that ground in detail.
Game-by-Game Rasterization Results at 1440p
In Cyberpunk 2077 with ray tracing disabled and Ultra preset enabled, the 245K led by around 6-8 frames per second in average framerates, with a more noticeable gap in 1% lows. Cyberpunk’s engine has historically favored Intel’s P-core performance, and that pattern continues with Arrow Lake. The 9600X still produced very playable numbers – nothing here is unacceptable – but Intel’s hybrid architecture handled the game’s CPU workload threads more aggressively.
Counter-Strike 2 told a different story. The 9600X’s tighter per-core performance and lower latency made a visible difference in 1% low frametimes, which is exactly the stat competitive players care about. Average framerates were close enough to call roughly even, but the 9600X produced more consistent frame delivery, and in a game where frame timing consistency translates to input feel, that’s not a trivial difference. CS2 has always been sensitive to CPU scheduling behavior, and Zen 5’s improvements in branch prediction and front-end efficiency show up here.
In Hogwarts Legacy, both chips performed almost identically across average and 1% low metrics. This game’s engine distributes its CPU load broadly enough that the architectural differences between Zen 5 and Arrow Lake don’t produce measurable separation at 1440p with a high-end GPU in the loop. Frame delivery was smooth on both platforms, hovering near the same ceiling.
Baldur’s Gate 3, particularly in Act 3 where CPU overhead from NPC simulation and event processing compounds, gave the 245K an edge again. The additional E-cores on Intel’s chip provided enough parallel processing headroom to keep frametimes flatter in the most demanding outdoor city areas. The 9600X dipped more noticeably in 1% lows during those sequences, though for a game that runs at a slower pace, the practical impact on the experience is minimal.
Alan Wake 2 without path tracing, running Northlight’s rasterization pipeline, was effectively a draw. Both chips hovered within 2-3 fps of each other across all metrics. Northlight’s rendering workload is GPU-bound at this resolution even with an RTX 4080 Super, and neither CPU had room to differentiate itself against that ceiling. The results here are a reminder that many modern titles at 1440p are closer to GPU-limited than the spec sheet comparisons suggest.
Power, Thermals, and Platform Realities
The 9600X’s 65W TDP advantage is real and it shows up clearly in power draw measurements under sustained gaming loads. Intel’s 245K routinely pulled 150-180W during gaming workloads with PL1 and PL2 limits unlocked, which is typical for Intel’s mainstream K-series parts. The 9600X stayed well under 90W in most titles. That gap means the 9600X runs cooler on modest cooling hardware, generates less heat in compact cases, and puts less stress on VRM configurations. For small form factor builds especially, the 9600X’s thermal profile is a real practical advantage.
Platform cost also factors in here. AM5 Z890 equivalents exist, but X670E boards that support the 9600X are now available at more accessible price points as the platform has matured. Intel’s Z890 ecosystem for the 245K tends to push platform costs higher, especially when chasing the memory speeds where Arrow Lake performs best. Neither chip is cheap to build around correctly, but the AMD ecosystem currently offers more flexibility at the lower end of motherboard pricing without sacrificing meaningful performance.
Which Chip Wins at 1440p Rasterization
Across the tested titles, the 245K leads in games that lean on high single-thread performance and can distribute work across its E-core cluster effectively – open world games, heavily simulated RPGs, and titles optimized around Intel’s thread director. The margin is real but rarely dramatic, typically in the 5-10% range for average framerates and slightly wider for 1% lows in the 245K’s favor.
The 9600X wins on efficiency, platform longevity, and in competitive multiplayer titles where frame timing consistency outweighs raw throughput. If the build is going into a smaller case, or the target games skew toward CS2, Valorant, or similarly latency-sensitive titles, the Ryzen chip makes a strong case for itself. The 245K is the faster chip in rasterization-heavy AAA workloads at 1440p – but it costs more to cool, more to power, and more to platform around, and that gap in real-world gaming framerates rarely justifies those trade-offs on its own.
