Downfall

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 7 270K Plus is a 24-core, 24-thread desktop processor from the Core Ultra Series 2, built on Arrow Lake Refresh architecture using a 3 nm TSMC process. It carries a base clock of 3.70 GHz and a boost clock of 5.50 GHz, with a 125 W TDP and support for DDR5 memory on a dual-channel bus delivering 115.2 GB/s. The chip includes 36 MB of shared L3 cache, plus 192 KB of L1 and 3 MB of L2 per core. Its integrated Arc Xe-LPG Graphics with 64 execution units is present, though the discrete GPU handles rendering in this configuration.

In synthetic workloads, the CPU posts a Cinebench R23 multi-core score of 44,253 and a single-core score of 2,439, while Cinebench R20 results are 24,461 multi-core and 3,453 single-core. PassMark multithread testing yields 68,574, with a single-thread score of 5,068. The processor sits at the 96th percentile among all CPUs, and its average benchmark score of 93,785 places it essentially even with the Intel Xeon 6520P (93,786, 0% delta), while trailing the AMD EPYC 4564P by 1.5% (95,183) and the AMD EPYC 9175F by 1.9% (95,615). The closest rival below is the AMD EPYC 4565P at 95,764, a 2.1% gap.

For Downfall, a horror title that leans on sustained frame pacing over raw multithreading, the 270K Plus's high boost clock and strong single-core performance are the relevant attributes. The game's measured FPS at 1080p Low reaches 175 average, which suggests the CPU has ample headroom to feed the GPU at lower resolutions where rendering overhead is lighter. The 24 threads are more than adequate for a game of this era; the data shows no signs of CPU bottlenecking even at the highest frame rates recorded. The processor's 96th percentile standing reinforces that it outperforms the vast majority of installed CPUs, making it a robust foundation for this pairing.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is a RDNA 2.0 part based on the Navi 23 chip, fabricated on TSMC's 7 nm process with 11,060 million transistors on a 237 mm² die. It operates with a base clock of 1626 MHz, a boost clock of 2491 MHz, and a game clock of 2044 MHz. Memory consists of 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The GPU features 1,792 shading units, 112 texture mapping units, and 64 raster output units, with 28 ray accelerators. Its compute throughput is 8.928 TFLOPS FP32, and it supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6.

In benchmark terms, the RX 6600 scores 15,096 in PassMark G3D and 6,554 in GPU compute, placing it at the 63rd percentile among all GPUs. Its average benchmark score of 19,036 is nearly identical to the NVIDIA Quadro K6000 (19,030, 0% delta) and the NVIDIA GeForce RTX 4050 Mobile (19,049, -0.1% delta). The NVIDIA Tesla K20m is 0.3% higher at 19,089, while the NVIDIA RTX 2000 Ada Generation trails by 0.4% at 18,954. The GPU's 8 GB VRAM is a notable constraint in Downfall at higher settings, particularly at 4K.

The data supports this interpretation: at 4K Ultra, the average FPS drops to 33, while 4K High yields 52 average and 4K Medium reaches 64. The RX 6600's 8 GB frame buffer is likely a limiting factor at 4K Ultra, where texture and geometry demands can exceed available memory, causing the steep performance cliff. At 1080p, the same GPU produces 175 FPS at Low, 143 at Medium, and 117 at High, indicating that at lower resolutions the card's memory bandwidth and compute are sufficient for smooth play. The 224.0 GB/s bandwidth is adequate for 1080p and 1440p, but the 128-bit bus shows its limits as resolution climbs.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of the Intel Core Ultra 7 270K Plus with the AMD Radeon RX 6600 ranks 2,270 out of 2,928 tested combinations in Downfall. That places it in the lower portion of the database, around the 22nd percentile of all combos tested for this game. The ranking reflects the GPU's mid-tier position (63rd percentile) rather than the CPU's strong showing (96th percentile), indicating that the graphics card is the primary determinant of this combo's overall standing.

The gap between the CPU's high percentile and the combo's low rank is instructive. While the 270K Plus is a top-tier processor, the RX 6600 is a mainstream GPU, and Downfall's performance scales more with graphics hardware than with processor capability. The combo rank of 2,270 out of 2,928 means that roughly three-quarters of tested systems outperform this pairing in this game, which is consistent with the RX 6600's 63rd percentile GPU standing. Systems with higher-tier GPUs paired with weaker CPUs would likely rank above this combo, as the game's frame rates are more sensitive to GPU compute and VRAM than to CPU thread count.

That said, the combo's measured FPS shows it can still deliver playable results at most settings. At 1080p Medium, it averages 143 FPS, and at 1440p High, it holds 84 FPS. The rank is a relative measure against all tested combos, and the data suggests that the CPU is not the limiting factor; upgrading the GPU would yield a substantially better rank, while upgrading the CPU alone would not move the needle much in Downfall.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 175 FPS, Medium averages 143 FPS with a minimum of 122 and a maximum of 164, High averages 117 FPS, and Ultra drops to 73 FPS. The step from High to Ultra is a 44 FPS loss, indicating that Ultra settings impose a significant load on the RX 6600's compute and memory resources.

Moving to 2560x1440, the averages decline predictably. Low settings yield 125 FPS, Medium averages 102 FPS with a range of 87 to 117, High comes in at 84 FPS, and Ultra falls to 52 FPS. The transition from 1080p to 1440p at each setting shows a consistent reduction: Low drops by 50 FPS, Medium by 41 FPS, High by 33 FPS, and Ultra by 21 FPS. The smaller absolute drop at Ultra suggests that the GPU is already near its limits at 1080p Ultra, so the additional resolution has less relative impact.

At 3840x2160, the results show a clear ceiling. Low settings average 78 FPS, Medium averages 64 FPS with a minimum of 54 and a maximum of 73, High averages 52 FPS, and Ultra drops to just 33 FPS. The 4K Ultra result is below the 60 FPS threshold that most players consider smooth, and even 4K High at 52 FPS is borderline. The data reveals a pattern where the RX 6600 can handle 1080p at all settings comfortably, 1440p at Medium and High reasonably, but 4K only at Low or Medium settings for acceptable frame rates.

The min/max data available for Medium settings across all resolutions shows the frame time consistency. At 1080p Medium, the spread from 122 to 164 is 42 FPS; at 1440p Medium, the spread narrows to 30 FPS (87 to 117); at 4K Medium, the spread is 19 FPS (54 to 73). This tightening at higher resolutions indicates that the GPU is more consistently saturated, reducing variance as it approaches its performance ceiling.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling from 1080p to 4K reveals which component constrains this system. At Low settings, the average FPS drops from 175 at 1080p to 125 at 1440p (a 28.6% reduction) and then to 78 at 4K (a 55.4% reduction from 1080p). At High settings, the progression is 117 to 84 to 52, representing a 28.2% drop to 1440p and a 55.6% drop to 4K. At Ultra settings, the figures are 73 to 52 to 33, with a 28.8% drop to 1440p and a 54.8% drop to 4K.

The consistency of these percentage drops—roughly 28% from 1080p to 1440p and 55% from 1080p to 4K across all settings—indicates that the GPU is the limiting component. If the CPU were the bottleneck, the frame rates would show less scaling with resolution, as the processor's workload would remain constant while the GPU's load increases. Instead, the nearly linear relationship between pixel count and FPS reduction points squarely at the RX 6600's rendering capabilities.

The 4K Ultra result of 33 FPS is particularly telling. The RX 6600's 8 GB VRAM and 224.0 GB/s bandwidth are insufficient for the demands of 4K Ultra in Downfall, causing a steep decline from the 52 FPS at 4K High. The gap between High and Ultra at 4K (19 FPS) is larger than the gap at 1080p (44 FPS difference from 117 to 73, but relative to the higher baseline) in percentage terms, suggesting that Ultra settings at 4K push the GPU past its memory or compute limits. The CPU, by contrast, shows no signs of strain; its high single-core performance and 96th percentile ranking mean it can easily feed the GPU at all resolutions tested.
