# How This Combo Ranks

The AMD Ryzen 9 7900X paired with the Intel Arc B370 lands at rank 2517 out of 2740 tested combos in Fortnite. That places this configuration in the bottom 9% of all tested setups, which is a striking result given the CPU's pedigree. The data suggests this is a severely GPU-limited pairing—the Arc B370 sits at the 5th percentile among all GPUs, while the Ryzen 9 7900X sits at the 91st percentile among all CPUs. This is a textbook case of a top-tier processor being held back by an entry-level graphics solution.

The combo's rank of 2517 means roughly 223 other combinations performed worse in this game, but over 2,500 combinations delivered higher frame rates. For a battle royale title where competitive play often demands high refresh rates, this ranking indicates the combo struggles to deliver the kind of performance most players would target. The data shows that even at 1080p Low settings—the most performance-friendly configuration measured—the average FPS only reaches 104, which is playable but far from the high-refresh territory that competitive Fortnite players typically seek.

GPU Role

The Intel Arc B370 is built on Intel's Xe3-LPG architecture and uses the Panther Lake chip. It features 1,280 shading units, 40 texture mapping units, and 20 raster output pipelines. The GPU also includes 10 ray tracing cores, though Fortnite's implementation of ray tracing is not directly measured in this data. The clock speeds are notable: a base clock of 300 MHz and a boost clock of 2,400 MHz. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s, with FP32 performance rated at 6.144 TFLOPS.

The memory configuration is unusual—the Arc B370 uses system shared memory rather than dedicated VRAM. This means the GPU relies on the CPU's DDR5 memory through the system's dual-channel configuration, with bandwidth listed as "System Dependent." The Ryzen 9 7900X supports DDR5 with a memory bandwidth of 83.2 GB/s, but the actual bandwidth available to the iGPU will depend on the specific memory configuration installed. This shared memory architecture likely contributes to the performance ceiling observed in the measured FPS data.

The GPU's benchmark results are telling: it scores 1,184 in 3DMark Steel Nomad DX12, which places it at the 5th percentile among all GPUs. Its nearest rivals in the benchmark database are the ATI Mobility Radeon HD 5570 (scoring 1,186, a 0.2% difference), the ATI Radeon HD 5770 (scoring 1,190, a 0.5% difference), and the AMD Radeon HD 7650M (scoring 1,192, a 0.7% difference). These are all older discrete GPUs, which puts the Arc B370's performance in perspective—it's competing with hardware from a previous era despite being a modern integrated solution.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture (codenamed Raphael). It operates on the AMD Socket AM5 platform and is built on TSMC's 5 nm process node. The base clock is 4.70 GHz with a boost clock of 5.60 GHz. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The CPU supports DDR5 memory in a dual-channel configuration.

The CPU's benchmark results are impressive across the board. In Cinebench R23, it scores 29,300 in multi-core and 2,016.5 in single-core. Geekbench shows 19,267 in multi-core and 2,617 in single-core. PassMark multi-thread performance is 51,406, with a single-thread score of 4,238. The 3DMark results show strong scaling: 1,093 in single-thread, 2,137 in 2-thread, 4,151 in 4-thread, 7,798 in 8-thread, and 12,536 in max-thread tests. This scaling indicates the processor handles both lightly-threaded and heavily-threaded workloads effectively.

The CPU's nearest rivals in the benchmark database include the AMD EPYC 7313P (scoring 53,206, a 0.2% difference), the Intel Xeon Phi 7290 (scoring 53,469, a 0.3% difference), the Intel Xeon 634 (scoring 52,974, a 0.6% difference), and the Intel Core i7-14700F (scoring 53,620, a 0.6% difference). The CPU's average benchmark score is 53,288, placing it at the 91st percentile among all CPUs.

In Fortnite, this CPU is clearly not the bottleneck. At 1080p Low settings, the combo achieves 104 FPS, but the CPU is capable of far more in other contexts. The 3DMark 16-thread score of 10,972 and max-thread score of 12,536 suggest the CPU has substantial headroom that the Arc B370 simply cannot utilize in this game. The data implies that if paired with a more capable GPU, this CPU would likely deliver significantly higher frame rates in Fortnite.

FAQ

Q: Why does this combo rank so low despite having a powerful CPU?

The PassMark single-thread score is 4,238, while the multi-thread score is 51,406. This shows strong performance in both metrics, though the multi-thread scaling is particularly notable for a 12-core processor.

Q: How does the FPS drop from 1080p to 4K at the same settings?

A: At Low settings, the average FPS drops from 104 at 1920x1080 to 66 at 2560x1440 (a 36.5% reduction) and then to 35 at 3840x2160 (a 66.3% reduction from 1080p). At High settings, the drop is from 57 at 1080p to 36 at 1440p to 19 at 4K. This steep decline with resolution indicates the GPU is the limiting component.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-limited performance. At Low settings, the average FPS goes from 104 at 1920x1080 to 66 at 2560x1440 to 35 at 3840x2160. This represents a 36.5% drop from 1080p to 1440p and a 66.3% drop from 1080p to 4K. At High settings, the progression is 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K—a 36.8% drop from 1080p to 1440p and a 66.7% drop from 1080p to 4K.

The consistency of these percentage drops across different quality settings is telling. Whether at Low, Medium, High, or Ultra, the relative performance loss between resolutions is nearly identical. This strongly suggests that the GPU is the bottleneck across all measured configurations. If the CPU were the limiting factor, we would expect to see smaller performance differences at higher resolutions (where GPU load increases) and larger differences at lower resolutions (where CPU load becomes more significant). The data shows the opposite pattern: the FPS scales almost exactly with the number of pixels being rendered.

At Medium settings, the data includes min and max FPS values. At 1920x1080, the average is 73 FPS with a min of 62 and max of 84. At 2560x1440, the average drops to 46 FPS with a min of 39 and max of 53. At 3840x2160, the average is 25 FPS with a min of 21 and max of 28. The tight min-max ranges relative to the average suggest relatively consistent frame pacing, though the overall performance is low.

Settings Recommendations

The measured data provides a clear picture of what settings deliver the best experience for this combo. At 1920x1080, Low settings achieve 104 FPS average, which is the only configuration that breaks the 100 FPS threshold. Medium settings at 1080p deliver 73 FPS average, while High settings drop to 57 FPS, and Ultra falls to 37 FPS. For players targeting smooth, responsive gameplay at 1080p, Low settings are the clear choice.

At 2560x1440, the situation becomes more constrained. Low settings achieve 66 FPS average, Medium delivers 46 FPS, High drops to 36 FPS, and Ultra falls to 24 FPS. At this resolution, even Low settings may struggle to maintain consistently high frame rates, though 66 FPS is playable for most gaming scenarios. At 3840x2160, all settings produce sub-60 FPS results, with Low at 35 FPS, Medium at 25 FPS, High at 19 FPS, and Ultra at 13 FPS. 4K gaming is not a viable option for this combo in Fortnite.

The data suggests that 1080p Low is the only configuration that provides a consistently smooth experience. The jump from Low to Medium at 1080p costs 31 FPS (a 29.8% reduction), which is a significant trade-off for the visual quality improvement. Players who prioritize visual fidelity over frame rate might consider Medium at 1080p, but the data clearly indicates that Low settings offer the best balance of performance for this hardware combination.

Measured FPS Breakdown

1920x1080:

• Ultra: 37 FPS average
• High: 57 FPS average
• Medium: 73 FPS average (min 62, max 84)
• Low: 104 FPS average

2560x1440:

• Ultra: 24 FPS average
• High: 36 FPS average
• Medium: 46 FPS average (min 39, max 53)
• Low: 66 FPS average

3840x2160:

• Ultra: 13 FPS average
• High: 19 FPS average
• Medium: 25 FPS average (min 21, max 28)
• Low: 35 FPS average

The full dataset shows that the combo's performance degrades predictably as both resolution and quality settings increase. At 1080p Low, the combo achieves its best measured performance at 104 FPS. At the opposite extreme, 4K Ultra produces just 13 FPS, which is effectively unplayable for a fast-paced battle royale game. The Medium settings at each resolution provide the only complete min/max data, showing frame ranges of 62-84 at 1080p, 39-53 at 1440p, and 21-28 at 4K. These ranges indicate that frame pacing remains relatively stable, but the absolute performance levels are the real constraint.

The data implies that this combo is best suited for 1080p gaming with lower quality settings. The Ryzen 9 7900X provides ample CPU performance, but the Arc B370's system shared memory architecture and low benchmark scores (1,184 in 3DMark Steel Nomad DX12, 5th percentile) create a hard ceiling on achievable frame rates. Players using this configuration should expect to compromise significantly on visual quality to achieve playable performance, and 4K gaming is effectively out of reach for this title.
