AMD vs Intel at 1440p: Ray Tracing Changes the Equation
Ray tracing has moved from a marketing checkbox to a genuine performance consideration at 1440p, and the CPU sitting in your system matters more than most people expect. With titles like Cyberpunk 2077, Alan Wake 2, and Indiana Jones and the Great Circle leaning hard on ray-traced lighting and reflections, the processing overhead on the CPU side is no longer trivial. That puts AMD’s Ryzen 7 9800X3D and Intel’s Core Ultra 7 265K in direct competition for a very specific kind of buyer: someone running a high-end GPU at 1440p and asking how much their processor is limiting them.
The 9800X3D brings AMD’s 3D V-Cache technology to the Zen 5 architecture, stacking 64MB of additional L3 cache on top of the standard die. The Core Ultra 7 265K runs on Intel’s Arrow Lake architecture with 20 cores across performance and efficiency configurations. On paper, Intel’s core count looks attractive. In practice, ray tracing at 1440p tells a different story depending entirely on which game you load.
Cyberpunk 2077 and the Ray Tracing Ceiling
Cyberpunk 2077 with Overdrive Mode enabled – which activates full path tracing – is the most punishing real-world test available. Paired with an RTX 4090 at 1440p, the 9800X3D consistently holds higher average frame rates in Night City’s densest districts compared to the Core Ultra 7 265K. The gap sits comfortably in the range where it’s visible during gameplay, not just in benchmark screenshots. AMD’s V-Cache advantage is well-documented in CPU-sensitive workloads, and path tracing appears to fall squarely in that category because the CPU handles scene traversal data that feeds the ray-tracing pipeline.
The Core Ultra 7 265K is not slow here. It manages respectable frame rates and doesn’t produce the kind of stutter that would ruin the experience. But it trails the 9800X3D consistently across multiple runs, and the margin widens as scene complexity increases – downtown areas, heavy rain, reflective surfaces stacked on top of each other. Arrow Lake’s architecture made efficiency gains but gave up some raw single-threaded responsiveness compared to Raptor Lake, and that deficit shows up specifically in workloads where cache latency determines how quickly the CPU feeds the GPU.
Frame time consistency is the more interesting metric here. The 9800X3D’s 1% lows stay closer to its average frame rate, which translates to smoother perceived motion even when average frame rates look similar. The Core Ultra 7 265K shows wider variance in the 1% and 0.1% low numbers, suggesting the CPU occasionally becomes a bottleneck in burst-demand moments – exactly when ray-traced scenes are making the biggest demands on the system.
DLSS and FSR complicate this comparison in a meaningful way. When upscaling is active and frame generation is layered on top, the CPU’s workload shifts. Frame generation handled by the GPU reduces how often the CPU needs to produce full rendered frames, which partially closes the gap between the two processors. Buyers planning to run DLSS 4 with Multi Frame Generation will see the 9800X3D’s lead compress noticeably. Without upscaling – native 1440p with full ray tracing – the AMD chip’s advantage is at its widest.
Alan Wake 2 and Real-World Ray Tracing Variety
Alan Wake 2 uses a different ray-tracing implementation than Cyberpunk – Remedy’s Northlight engine handles reflections, shadows, and global illumination through a mix of ray tracing and screen-space techniques rather than full path tracing. This tests a broader cross-section of ray-tracing scenarios, and here the results are more nuanced. The 9800X3D still leads, but the margin is smaller because the game’s engine is less cache-hungry than Night City’s street-level chaos.
Indiana Jones and the Great Circle, running on id Tech 9 with hardware-accelerated ray tracing enabled, sits closer to even between the two chips. id Software’s engine has always been exceptionally well-optimized for multi-core workloads, and the Core Ultra 7 265K’s efficiency cores contribute meaningfully to background thread management. For players whose library skews toward id Tech games or similarly optimized titles, Intel’s chip closes the performance gap considerably.
Power, Heat, and the Value Context
The Core Ultra 7 265K runs hotter and draws more power under sustained gaming loads than the 9800X3D. Arrow Lake was supposed to improve efficiency over Raptor Lake, and it does in productivity workloads, but under gaming conditions the 265K still demands a capable cooler and a case with reasonable airflow. The 9800X3D runs cooler by a meaningful margin and draws less power during play sessions, which matters for small form factor builds and for anyone running a tighter power budget.
Pricing has shifted since both chips launched. The 9800X3D launched at a premium and has held its value stubbornly because demand stayed strong. The Core Ultra 7 265K has seen more price movement and can regularly be found at a discount compared to launch MSRP. Depending on when you’re buying and what platform costs you factor in – motherboard, DDR5 memory – the total system cost can end up comparable despite the list price difference. Intel’s Z890 platform and AMD’s AM5 platform are both locked into DDR5, so memory pricing doesn’t differentiate them the way it once did.
For anyone already on an AM4 or AM5 platform, the upgrade math is straightforward: the 9800X3D is a direct drop-in on AM5 boards with a BIOS update. Intel buyers are looking at a full platform replacement. That platform lock-in consideration – more than the per-game frame rate numbers – may be what decides the purchase for most upgraders.

Who Should Buy Which Chip
The Ryzen 7 9800X3D is the stronger choice specifically for ray-traced gaming at 1440p on a high-end GPU. Its V-Cache advantage is real, consistent, and most visible in exactly the demanding titles that enthusiast buyers are likely to run. If the goal is the highest possible performance in the games pushing ray tracing hardest – and native resolution without upscaling is part of that goal – AMD wins this matchup without much ambiguity.
The Core Ultra 7 265K makes a stronger case when ray tracing is only one piece of a larger use case. Content creators, streamers running local encoding, and users splitting time between heavy productivity workloads and gaming will find Intel’s additional cores and strong multi-threaded performance more useful. The gaming gap in ray-traced titles is real, but it is not large enough to be disqualifying for someone who values workload flexibility. What it cannot do is beat the 9800X3D in the specific scenario this comparison tests – high-fidelity ray tracing at 1440p, native resolution, GPU-limited but occasionally CPU-bound – and that gap exists across enough major titles to be a reliable pattern rather than a one-game outlier.
