AMD Radeon 740M vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The two integrated graphics processors in this comparison cannot be benchmarked against each other directly. The database contains no shared test that both the AMD Radeon 740M and the Intel Arc B370 have completed. The AMD Radeon 740M has results in two OpenCL and Vulkan compute tests, while the Intel Arc B370 has only a single DirectX 12 test score. As a result, the head-to-head comparison relies on each product's average benchmark score and its position relative to its nearest rivals.

The AMD Radeon 740M records an average benchmark score of 12870. That places it at the 53rd percentile of all GPUs in the database. Its nearest rival is the AMD FirePro W5100 with an average score of 12847, putting the Radeon 740M ahead by 0.2 percent. The Radeon Pro 455 trails by 0.3 percent at 12831, and the NVIDIA GeForce GTX 590 also sits 0.3 percent behind at 12830. On the other side, the AMD Radeon RX 580 posts 12928, which is 0.4 percent higher than the 740M. These deltas are remarkably tight, all within a single percentage point. The data shows the 740M sits in a dense cluster of mid-range desktop and mobile GPUs from several generations ago.

The Intel Arc B370 delivers an average benchmark score of 1184. That score places it at the 5th percentile of all GPUs, a far lower standing than the Radeon 740M. Its nearest rival is the ATI Mobility Radeon HD 5570 at 1186, which is 0.2 percent higher. The ATI Radeon HD 5770 scores 1190, 0.5 percent above the B370, and the AMD Radeon HD 7650M reaches 1192, 0.7 percent higher. The AMD FirePro M2000 scores 1168, which is 1.4 percent lower than the B370. The differences here are also small, but the entire rival group consists of much older hardware.

The raw score gap between the two products is substantial. The AMD Radeon 740M averages 12870 versus 1184 for the Intel Arc B370, a difference of roughly 10.9 times. However, these averages come from different benchmark suites, so the comparison is not apples to apples. The 740M's scores derive from Geekbench compute workloads, while the B370's single score comes from a 3DMark Steel Nomad DirectX 12 test. The database does not provide a normalized cross-benchmark conversion, so any direct numerical comparison between the two averages should be treated cautiously.

Architecture Differences

The two processors come from different manufacturers and use fundamentally different designs. The AMD Radeon 740M uses the Phoenix2 chip built on RDNA 3.0 architecture, fabricated by TSMC on a 4 nm process. It belongs to the Navi III IGP generation and is the successor to the Navi II IGP. The Intel Arc B370 uses the Panther Lake chip built on Xe3-LPG architecture, fabricated by Intel on a 3 nm process. It belongs to the Arc Graphics-M generation for Panther Lake.

The AMD chip contains 20,900 million transistors on a 137 mm² die, giving a transistor density of 152.6 million per square millimeter. The Intel chip's transistor count and die size are listed as unknown in the database, so no density figure is available for comparison.

The execution resources differ significantly. The Radeon 740M has 256 shading units, 16 texture mapping units, and 8 raster operation pipelines. It also includes 4 ray tracing cores. The Intel Arc B370 has 1280 shading units, 40 texture mapping units, and 20 ROPs, along with 10 ray tracing cores. The Intel part offers five times the shading units, 2.5 times the TMUs, 2.5 times the ROPs, and 2.5 times the ray tracing cores compared to the AMD part.

Clock speeds show the AMD part running higher. The Radeon 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. Despite the lower clocks, the Intel part's larger execution resource count produces higher theoretical throughput. The Radeon 740M delivers 2.867 TFLOPS of FP32 compute and 2.867 TFLOPS of FP16 compute at a 1:1 ratio. The Intel Arc B370 delivers 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16 at a 2:1 ratio. The Intel part more than doubles the FP32 throughput and more than quadruples the FP16 throughput.

Pixel and texture rates follow the same pattern. The Radeon 740M reaches 22.40 GPixel/s and 44.80 GTexel/s. The Intel Arc B370 reaches 48.00 GPixel/s and 96.00 GTexel/s, roughly double the AMD figures in both categories.

Memory architecture is identical in structure. Both use system shared memory with a system dependent bus width and bandwidth. Neither has dedicated VRAM. The power profiles differ notably despite both being integrated graphics. The Radeon 740M has a TDP of 45 W, while the Intel Arc B370 has a TDP of 25 W. Both use no power connectors and are listed as IGP slot width.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface differs: the Radeon 740M uses PCIe 4.0 x8, while the Intel Arc B370 is listed simply as IGP. Display outputs are motherboard dependent for the AMD part and portable device dependent for the Intel part.

Where Each One Wins

The AMD Radeon 740M wins on overall benchmark standing. Its 53rd percentile rank versus the Intel Arc B370's 5th percentile represents a massive gap in the database's performance distribution. The 740M's average score of 12870 places it among capable discrete GPUs from prior generations, including the Radeon RX 580 and GeForce GTX 590. The B370's 1184 average places it alongside integrated and low-end mobile parts from over a decade ago.

The AMD part also wins on raw clock speed. Its boost clock of 2800 MHz exceeds the Intel part's 2400 MHz boost. The base clock advantage is even larger at 800 MHz versus 300 MHz, a 2.7 times difference. For workloads that scale with clock frequency and do not fully utilize the wider execution resources, the Radeon 740M should hold an advantage.

The Intel Arc B370 wins on theoretical compute throughput. Its 6.144 TFLOPS FP32 figure is 2.14 times the Radeon 740M's 2.867 TFLOPS. The FP16 advantage is even larger at 12.29 TFLOPS versus 2.867 TFLOPS, a 4.3 times difference. The Intel part's pixel rate of 48.00 GPixel/s doubles the AMD part's 22.40 GPixel/s, and the texture rate of 96.00 GTexel/s doubles the AMD part's 44.80 GTexel/s. These figures suggest the Intel architecture can fill its wider pipelines more effectively in throughput-bound scenarios.

The Intel part also wins on power efficiency on paper. Its 25 W TDP is 20 W lower than the 45 W TDP of the Radeon 740M, while delivering more than double the FP32 throughput. That translates to a much higher theoretical performance per watt, although the database does not include measured power consumption data.

The Intel part has a newer process node at 3 nm versus 4 nm, and it uses the Xe3-LPG architecture which is a newer generation than RDNA 3.0. The release dates differ: the Radeon 740M launched on January 30, 2024, while the Intel Arc B370 launched on January 26, 2026, roughly two years later.

The Verdict

The data presents a clear split between the two products. The AMD Radeon 740M delivers far better real-world benchmark results as recorded in the database. Its 12870 average score and 53rd percentile rank place it squarely in the range of capable discrete GPUs. The Intel Arc B370's 1184 average and 5th percentile rank place it at the bottom of the performance distribution. For any application that relies on actual measured performance, the Radeon 740M is the stronger choice.

However, the Intel Arc B370's architectural specifications tell a different story on paper. Its 1280 shading units, 40 TMUs, and 10 ray tracing cores give it a massive resource advantage. Its theoretical FP32 throughput of 6.144 TFLOPS and FP16 throughput of 12.29 TFLOPS far exceed the Radeon 740M's figures. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s double the AMD part's corresponding rates. The B370 achieves all this at a lower TDP of 25 W versus 45 W. These specifications suggest the Intel part has significantly more raw capability that its single benchmark result does not currently reflect.

The release dates explain part of this discrepancy. The Radeon 740M launched on January 30, 2024, and has accumulated benchmark results across multiple test suites. The Intel Arc B370 launched on January 26, 2026, and has only one recorded benchmark result. The database may not yet reflect the B370's full performance profile, as its single 3DMark Steel Nomad score cannot be directly compared to the Geekbench scores of the 740M.

The practical recommendation depends on which data source carries more weight. For users who prioritize verified benchmark performance today, the AMD Radeon 740M is the proven quantity. For users who prioritize architectural capability and theoretical throughput, the Intel Arc B370 shows more potential, particularly in FP16 workloads where its 2:1 ratio gives it a 4.3 times advantage over the AMD part. The B370's newer 3 nm process and lower TDP also suggest better efficiency characteristics, though the database does not include measured power data.

The choice also depends on the target platform. The Radeon 740M uses PCIe 4.0 x8 and motherboard dependent display outputs, indicating a laptop or desktop IGP design. The Intel Arc B370 lists its bus interface as IGP and its display outputs as portable device dependent, suggesting a mobile-first integration. Users building a system around one or the other platform will find their options constrained by the host processor, not by the GPU alone.

Given the 53rd versus 5th percentile standings, the Radeon 740M is the safer pick for immediate use. The Intel Arc B370 warrants attention but requires additional benchmark data before its theoretical advantages can be confirmed in practice.
