Inside

Inside is a puzzle platformer from 2016 that places very different demands on the CPU and GPU than most modern shooters. The measured data for the AMD Ryzen 5 2600 paired with the AMD Radeon RX 6600 XT shows a configuration that is clearly GPU-bound at higher resolutions, but which begins to show CPU limitations at 1080p. This analysis breaks down how the frame rate scales with resolution, what each component contributes, and which settings provide the most balanced experience.

Resolution Scaling

The frame rate data reveals a classic pattern of GPU-bound scaling, but with a notable exception at the top end. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 138 FPS to 103.2 FPS, a reduction of roughly 25%. The subsequent jump to 3840x2160 yields 63.9 FPS, which is a further 38% drop. This steep decline at 4K is the signature of the GPU hitting its raw pixel throughput ceiling.

However, the Low settings row tells a different story about the system balance. At 1080p Low, the configuration produces 207.8 FPS. At 1440p Low, it still manages 181.4 FPS, and even at 4K Low it holds 127.2 FPS. The scaling from 1080p to 1440p is only a 13% drop, which is far less than the pixel count increase. This indicates that the CPU is the limiting factor at 1080p Low; the RX 6600 XT is not being fully utilized because the Ryzen 5 2600 cannot feed frames fast enough. Once the resolution rises, the GPU takes over as the primary constraint.

The Ultra preset confirms this interpretation. At 4K Ultra, the average is 60.1 FPS, which is nearly identical to the 63.9 FPS at High. The difference between High and Ultra at 4K is only 3.8 FPS, suggesting the visual settings are not dramatically increasing the shading load. The data indicates that 1440p is the sweet spot for this combo, where the CPU can still deliver enough frames to keep the GPU busy without overwhelming it, as shown by the 158.3 FPS Medium result at that resolution.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip on a 7 nm process from TSMC. Its performance profile in this game is defined by its memory subsystem and clock speeds. The GPU has 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The boost clock is rated at 2589 MHz, with a game clock of 2359 MHz. These specifications place it in the 71st percentile of all GPUs, with an average benchmark score of 27985.

Comparing to its nearest rivals, the RX 6600 XT is essentially tied with the NVIDIA GeForce GTX 980 Ti, which scores 27956, a delta of only 0.1%. It is also nearly identical to the AMD Radeon R9 M395X (27883, 0.4% higher). The data shows it lags the NVIDIA GeForce RTX 3070 by 0.9% in average benchmark score, but beats the AMD FirePro S7150 by 1.5%. This positioning suggests the GPU has enough raw compute for Inside, but the 8 GB VRAM is not the bottleneck here; the game's art style relies more on fill rate and memory bandwidth than capacity.

The GPU's role in the measured FPS is most evident at 4K. At that resolution, the High preset yields 63.9 FPS, which is close to the 60 FPS target. The fact that Ultra only drops this to 60.1 FPS indicates the GPU is hitting a hard limit on pixel processing. The pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are sufficient for the game's stylized visuals, but the 128-bit memory bus constrains performance when the resolution demands more data per frame.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor from the 2000 series, based on the Zen+ (Pinnacle Ridge) architecture on a 12 nm process. Its base clock is 3.40 GHz with a boost of 3.90 GHz. The CPU has 16 MB of shared L3 cache and supports dual-channel DDR4 memory with a bandwidth of 46.9 GB/s. Its benchmark scores place it in the 77th percentile of all CPUs, with an average score of 19616.

The CPU's performance in this puzzle platformer is characterized by its single-thread capabilities. In Cinebench R23, it scores 1579 in single-core and 11186 in multi-core. The PassMark single-thread score is 2239. These numbers are modest by modern standards, and the nearest rivals confirm this. The Intel Core i5-1345U scores 19691 (0.4% higher), while the AMD Ryzen 5 7530U scores 19508 (0.6% lower). The Intel Core i7-10700F is 0.7% higher, and the Intel Core i5-11600KF is 0.6% lower. The Ryzen 5 2600 sits squarely in the middle of this pack, which is telling for a game like Inside.

The measured FPS data shows the CPU limiting factor at 1080p Low, where the 207.8 FPS result is likely near the maximum that the Ryzen 5 2600 can produce for the game's logic and draw calls. The gap between 1080p Low (207.8 FPS) and 1440p Low (181.4 FPS) suggests that the CPU is still delivering similar frame times even as the GPU work increases. The 6 cores and 12 threads are sufficient for the game's physics and puzzle mechanics, but the older Zen architecture's single-thread performance becomes the ceiling at lower resolutions.

FAQ

Q: Why does the frame rate drop so much from 1080p to 4K at High settings?

A: The data shows a drop from 138 FPS at 1920x1080 to 63.9 FPS at 3840x2160, which is a 54% reduction. This steep decline indicates the GPU is the primary bottleneck at higher resolutions, as the RX 6600 XT's 256.0 GB/s memory bandwidth and 128-bit bus cannot keep up with the quadrupled pixel count.

Q: Is the Ryzen 5 2600 holding back the RX 6600 XT in this game?

A: Yes, but only at 1080p. The Low preset at 1920x1080 produces 207.8 FPS, which is likely near the CPU's maximum frame output. The CPU's single-thread score of 1579 in Cinebench R23 suggests it cannot feed the GPU faster, but at 1440p and 4K, the GPU becomes the limiting factor.

Q: What is the best resolution for this combo?

A: The data indicates 2560x1440 is the sweet spot. At Medium settings, the combo delivers 158.3 FPS, which is well above the 60 FPS threshold, while still providing a sharp image. At 1080p, the CPU limits performance, and at 4K, the GPU drops to near 60 FPS on High.

Q: How does the RX 6600 XT compare to its nearest rival in terms of raw GPU score?

A: The RX 6600 XT has an average benchmark score of 27985, which is 0.1% higher than the NVIDIA GeForce GTX 980 Ti (27956) and 0.4% higher than the AMD Radeon R9 M395X (27883). It is 0.9% lower than the RTX 3070 (28238).

Q: Does the Ultra preset provide a meaningful visual improvement over High at 4K?

A: No, not in terms of performance cost. The measured FPS at 4K Ultra is 60.1, which is only 3.8 FPS lower than High at 63.9. This suggests the Ultra preset adds minimal shading work, but the GPU is already near its limit.

Q: Is the CPU's multi-threaded performance relevant for this game?

A: Partially. The Ryzen 5 2600's multi-core score of 11186 in Cinebench R23 shows it has ample threads for the game's background tasks, but the single-thread score of 1579 is more critical for frame pacing. The data shows the CPU limiting at 1080p Low, where the high frame rate demands fast single-thread execution.

Measured FPS Breakdown

The measured frame rates provide a complete picture of the system's behavior across all settings and resolutions. At 1920x1080, the Low preset achieves 207.8 FPS, Medium drops to 191.7 FPS, High falls to 138 FPS, and Ultra sits at 135.6 FPS. The gap between Medium and High is significant at 53.7 FPS, indicating a major increase in rendering complexity. The difference between High and Ultra is only 2.4 FPS, showing diminishing returns.

Moving to 2560x1440, the Low preset still delivers 181.4 FPS, which confirms the GPU's efficiency at this resolution. Medium produces 158.3 FPS, High drops to 103.2 FPS, and Ultra yields 99.2 FPS. The scaling from 1080p to 1440p is more linear here, with High dropping by 34.8 FPS and Ultra by 36.4 FPS. This suggests the GPU is now the primary constraint, as the CPU has more headroom.

At 3840x2160, the frame rates compress dramatically. Low still manages 127.2 FPS, Medium drops to 99.4 FPS, High falls to 63.9 FPS, and Ultra bottoms out at 60.1 FPS. The jump from Medium to High at 4K is a 35.5 FPS loss, which is the largest single-step drop across all resolutions. This indicates the High preset at 4K pushes the GPU over its memory bandwidth limit. The Ultra preset at 4K is only 3.8 FPS lower than High, confirming the GPU is maxed out.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target display and desired frame rate. For a 60 Hz display at 3840x2160, the High preset at 63.9 FPS is the best choice, as it provides a smooth experience without the extra GPU load of Ultra, which only drops to 60.1 FPS. The Medium preset at 99.4 FPS is also viable for users who prefer a higher frame rate, but the visual quality difference from High is substantial.

For 1440p displays, the Medium preset at 158.3 FPS delivers an excellent balance of visual fidelity and performance. The High preset at 103.2 FPS is also acceptable for users who want more detail, but the 55.1 FPS gap between Medium and High suggests the latter carries a heavy cost. The Ultra preset at 99.2 FPS is nearly identical to High, so users should choose High for a small performance gain.

At 1080p, the CPU limits performance, so the Medium preset at 191.7 FPS is recommended for maximum smoothness without sacrificing too much visual quality. The High preset at 138 FPS is still well above 60 FPS and provides better textures, but the data shows the CPU is the bottleneck, not the GPU. The Ultra preset at 135.6 FPS offers no meaningful gain over High, so it should be avoided. The Low preset at 207.8 FPS is only for competitive play or very high refresh rate monitors, as the visual degradation is noticeable in this puzzle platformer.
