AMD Radeon 820M vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Radeon 820M and the Intel Arc B370. The only available performance data point belongs to the Intel Arc B370, which has one submitted 3DMark Steel Nomad DX12 score of 1184. The AMD Radeon 820M has no benchmark entries in the database, so a direct comparison of measured scores is not possible.

The Intel Arc B370's single benchmark result places it at the 5th percentile among all GPUs in the database. This percentile rank indicates that 95 percent of recorded graphics processors outperform it in this particular test. However, the database also shows the Arc B370's nearest rivals by average score, which provides context for interpreting its performance. The ATI Mobility Radeon HD 5570 averages 1186 points, which is 0.2 percent higher than the Arc B370's score. The ATI Radeon HD 5770 averages 1190 points, 0.5 percent higher. The AMD Radeon HD 7650M averages 1192 points, 0.7 percent higher. The AMD FirePro M2000 averages 1168 points, which is 1.4 percent lower than the Arc B370.

These delta percentages show that the Arc B370 sits within a very narrow performance band. Its score of 1184 is within 1.4 percent of all four nearest rivals, with three of those rivals slightly ahead and one slightly behind. The spread from the lowest rival score (1168) to the highest (1192) is only 24 points, meaning the Arc B370 is essentially at parity with this cluster of legacy discrete mobile and desktop GPUs.

For the AMD Radeon 820M, the database records zero benchmark scores and zero wins in the head-to-head comparison. The wins counter for both the Radeon 820M and the Arc B370 is zero, confirming that no direct benchmark victories can be attributed to either product from the available data.

Where Each One Wins

Without head-to-head benchmark results, any assessment of where each GPU wins must rely on the architectural specifications recorded in the database. The Intel Arc B370 has a clear structural advantage in raw compute resources. It uses 1280 shading units compared to 128 for the AMD Radeon 820M, a 10-fold difference in shader count. The Arc B370 also has 40 texture mapping units versus 8, and 20 render output units versus 4. The ray tracing core count is 10 for Intel and 2 for AMD.

These resource differences translate directly into the theoretical throughput figures in the database. The Intel Arc B370 delivers 6.144 TFLOPS of FP32 compute, while the AMD Radeon 820M delivers 716.8 GFLOPS. The Arc B370's FP16 throughput is 12.29 TFLOPS, achieved at a 2:1 ratio, while the Radeon 820M delivers 716.8 GFLOPS at a 1:1 ratio. Pixel fill rate for the Arc B370 is 48.00 GPixel/s versus 11.20 GPixel/s for the Radeon 820M. Texture fill rate is 96.00 GTexel/s versus 22.40 GTexel/s.

The AMD Radeon 820M does have advantages in certain areas. Its boost clock is 2800 MHz, which is 400 MHz higher than the Arc B370's 2400 MHz boost. The base clock is also higher at 400 MHz versus 300 MHz. The Radeon 820M uses a 4 nm process node from TSMC, while the Arc B370 uses Intel's 3 nm node. The Radeon 820M carries a 15 W TDP, while the Arc B370 is rated at 25 W. The Radeon 820M connects via PCIe 4.0 x8, while the Arc B370's bus interface is listed simply as IGP.

The Radeon 820M was released on 2025-02-28, while the Arc B370 has a release date of 2026-01-26. Both are listed as Active in production status. Neither product has a recorded launch MSRP in the database.

The Verdict

The data supports a clear conclusion for the Intel Arc B370 as the stronger performer. The recorded benchmark score of 1184 in 3DMark Steel Nomad DX12, combined with its 5th percentile rank and its theoretical throughput figures, indicates it is the more capable of the two integrated graphics solutions. The FP32 throughput of 6.144 TFLOPS is roughly 8.6 times higher than the Radeon 820M's 716.8 GFLOPS. The pixel rate of 48.00 GPixel/s is over 4 times higher than 11.20 GPixel/s. The texture rate of 96.00 GTexel/s is over 4 times higher than 22.40 GTexel/s.

The AMD Radeon 820M does not have any benchmark scores to compare, so its actual performance cannot be verified from the database. Its 50th percentile rank for all GPUs is based on no average benchmark score, which makes that rank unsubstantiated by measured results. The Arc B370's 5th percentile rank is based on an actual submitted score, even if that score is low relative to the full GPU population.

For users prioritizing raw compute and fill rates, the Intel Arc B370 is the clear choice. For users prioritizing lower power consumption, the AMD Radeon 820M's 15 W TDP is 10 W lower than the Arc B370's 25 W rating. The Radeon 820M also has a higher boost clock at 2800 MHz versus 2400 MHz, which could matter in burst workloads that scale with clock speed rather than shader count.

The Arc B370's nearest rivals are all older discrete GPUs, and it performs within 0.7 percent of three of them. This suggests the Arc B370, despite being a modern integrated solution, delivers performance comparable to a mid-range discrete GPU from roughly a decade earlier. The AMD Radeon 820M has no such comparison points in the database.
