AMD Radeon 8040S vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The database contains limited overlapping benchmark data for these two integrated GPUs. The AMD Radeon 8040S provides a broad set of PassMark test results, while the Intel Arc B370 has a single 3DMark Steel Nomad DX12 score. This makes direct head-to-head comparisons incomplete but still informative when examining each product’s recorded standing among all GPUs.

The AMD Radeon 8040S achieves a PassMark G3D score of 10578, which places it at the 17th percentile among all GPUs in the database. Its average benchmark score is 2440. The nearest rivals for the AMD part include the NVIDIA GeForce 710M with an average score of 2433 (a delta of 0.3% in AMD’s favor), the Intel HD Graphics 610 at 2425 (0.6% ahead), and the NVIDIA GeForce GT 710M at 2422 (0.7% ahead). The AMD Radeon RX 7400 sits slightly ahead at 2467, which means the 8040S trails that part by 1.1%. These deltas are small, indicating that the 8040S sits in a tightly packed performance cluster among older and low-end discrete GPUs.

In contrast, the Intel Arc B370 records a 3DMark Steel Nomad DX12 score of 1184, with an average benchmark score of 1184 and a percentile rank of 5 among all GPUs. Its nearest rivals are the ATI Mobility Radeon HD 5570 at 1186 (Intel trails by 0.2%), the ATI Radeon HD 5770 at 1190 (trailing by 0.5%), and the AMD Radeon HD 7650M at 1192 (trailing by 0.7%). The AMD FirePro M2000 sits behind at 1168, giving the Intel part a 1.4% advantage. The Arc B370 is essentially tied with these aging discrete GPUs from over a decade ago.

The AMD 8040S shows a much stronger PassMark G3D score relative to its own average, indicating that its compute-heavy workloads perform better than its overall average might suggest. The Intel B370’s single benchmark score is its only data point, so its percentile standing is directly derived from that one 3DMark result.

Where Each One Wins

The AMD Radeon 8040S delivers higher raw performance in the PassMark suite. Its G3D score of 10578 is substantially above the Intel B370’s 1184 in the 3DMark test, though these are different benchmark families and cannot be directly equated. The AMD part also posts PassMark DirectX 9, 10, 11, and 12 scores of 134, 48, 80, and 47 respectively, along with a G2D score of 1052 and a GPU compute score of 5138. The presence of multiple DirectX API results suggests the 8040S is tested across a wider range of legacy and modern workloads, while the Intel B370 has only been measured with a modern DX12 test.

In terms of percentile placement, the AMD 8040S at the 17th percentile outperforms the Intel B370 at the 5th percentile. This difference indicates that the AMD part ranks higher among all GPUs in the database, even though both are integrated solutions. The AMD’s average benchmark score of 2440 is more than double the Intel’s 1184, though again the test methodologies differ.

For workloads that rely on older DirectX APIs, the AMD 8040S has recorded scores in DirectX 9 (134) and DirectX 11 (80) that are higher than its DirectX 10 (48) and DirectX 12 (47) results. This suggests the AMD part performs relatively better in legacy API scenarios. The Intel B370 has no recorded scores for older DirectX versions, so its behavior in those situations remains unknown from the database.

Architecture Differences

The AMD Radeon 8040S uses the Strix Halo chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. The die size is recorded as 308 mm². The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, fabricated on a 3 nm process at Intel’s own foundry, with the die size listed as unknown.

Both GPUs are integrated parts (IGP slot width) with no power connectors and portable-device-dependent display outputs. The AMD part connects via PCIe 5.0 x16, while the Intel part uses an IGP bus interface. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The AMD 8040S has 1024 shading units, 64 texture mapping units, 32 raster output units, and 16 ray tracing cores. The Intel B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The AMD part therefore has more TMUs and ROPs but fewer shading units. The pixel rate for AMD is 89.60 GPixel/s versus Intel’s 48.00 GPixel/s. The texture rate for AMD is 179.2 GTexel/s compared to Intel’s 96.00 GTexel/s.

In terms of floating point performance, the AMD 8040S delivers 5.734 TFLOPS for FP32 and 5.734 TFLOPS for FP16 at a 1:1 ratio. The Intel B370 provides 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16 at a 2:1 ratio. This means the Intel part has a higher peak FP32 throughput and a much higher FP16 rate, while the AMD part maintains equal FP16 and FP32 rates.

Clock speeds differ significantly. The AMD 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz. The Intel B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The AMD part’s base clock is over four times higher than Intel’s, though boost clocks are closer. Power consumption is recorded at 55 W for AMD and 25 W for Intel, making the Intel part more power-efficient per watt on paper, though the performance differences complicate that comparison.

Both parts use system shared memory with system-dependent bandwidth. Neither has dedicated VRAM, tensor cores, or a known transistor count. The AMD part has a known predecessor (Polaris Mobile) while the Intel part has no recorded predecessor. The AMD part released on January 5, 2025, while the Intel part released on January 26, 2026. Both are currently marked as Active in production.

The Verdict

The recorded data shows the AMD Radeon 8040S holding a higher percentile rank (17th versus 5th) and a higher average benchmark score (2440 versus 1184). Its PassMark G3D result of 10578 demonstrates strong performance in the database’s general 3D testing, while its GPU compute score of 5138 indicates solid compute capability. The AMD part also delivers higher pixel and texture rates, with 89.60 GPixel/s and 179.2 GTexel/s respectively, which supports its stronger rasterization throughput.

The Intel Arc B370, despite having more shading units (1280 versus 1024) and higher FP32 peak throughput (6.144 TFLOPS versus 5.734 TFLOPS), is recorded with a lower percentile and a lower average score. Its single 3DMark result of 1184 places it near decade-old discrete GPUs such as the ATI Radeon HD 5770, which scores 1190. The Intel part’s lower power envelope of 25 W versus 55 W makes it more power-efficient, but the benchmark data shows it delivering less overall performance.

Users requiring higher raw graphics performance, particularly in legacy DirectX workloads, would find the AMD Radeon 8040S better suited based on its PassMark DirectX 9 score of 134 and DirectX 11 score of 80. The Intel Arc B370 offers higher FP16 throughput (12.29 TFLOPS) and a smaller process node (3 nm versus 4 nm), but these advantages do not translate into a higher benchmark standing in the database. The data indicates the AMD part is the stronger performer overall, while the Intel part trades performance for lower power consumption.
