AMD Radeon 740M vs Intel Arc Pro B390 Comparison

The Verdict

The database records two very different integrated graphics solutions. The AMD Radeon 740M, based on the Phoenix2 chip, is an established part with measured benchmark scores. The Intel Arc Pro B390, based on Panther Lake, is a newer entry with no recorded benchmark data in the database at this time.

The AMD Radeon 740M has an average benchmark score of 12870, placing it at the 53rd percentile of all GPUs. Its nearest rivals include the AMD FirePro W5100 (0.2% behind), AMD Radeon Pro 455 (0.3% behind), NVIDIA GeForce GTX 590 (0.3% behind), and AMD Radeon RX 580, which sits 0.4% ahead. These narrow margins indicate the 740M clusters tightly with older discrete graphics cards in aggregate performance.

The Intel Arc Pro B390 has no benchmark scores recorded, no average score, and no nearest rivals listed. Its percentile standing of 50 reflects the absence of measured data rather than a performance estimate. The database cannot confirm its real-world standing yet.

For those selecting between the two, the AMD Radeon 740M is the only option with verified performance data. It delivers measurable results in both OpenCL and Vulkan workloads. The Intel Arc Pro B390 remains an unverified quantity in this database; its specifications suggest a different class of hardware, but without recorded scores, any performance conclusion would be speculation. The data supports choosing the 740M when verified performance is required, while the B390 is a forward-looking option with no confirmed benchmark presence.

Architecture Differences

The AMD Radeon 740M uses the RDNA 3.0 architecture on a 4 nm TSMC process. Its chip, Phoenix2, packs 20,900 million transistors into a 137 mm² die, yielding a transistor density of 152.6 million per square millimeter. The architecture generation is listed as Navi III IGP (Phoenix), with a predecessor of Navi II IGP and a successor of Navi III IGP.

The Intel Arc Pro B390 uses the Xe3-LPG architecture on a 3 nm Intel process. Its chip is Panther Lake, and the generation is Arc Graphics-WM (Panther Lake). The database does not list transistor count, die size, or transistor density for this part. Its predecessor is HD Graphics-WM, and it has no recorded successor.

Both parts use System Shared memory with System Dependent bandwidth and bus width. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part connects via PCIe 4.0 x8, while the Intel part uses an IGP bus interface. The AMD 740M has a release date of January 30, 2024, while the Intel B390 has a release date of January 26, 2026.

The shading resources differ substantially. The AMD 740M has 256 shading units, 16 texture mapping units (TMUs), 8 render output units (ROPs), and 4 ray tracing cores. The Intel B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. These are six times, three times, three times, and three times the respective counts of the AMD part.

Head-to-Head Benchmarks

The database has no direct head-to-head benchmark results between the AMD Radeon 740M and the Intel Arc Pro B390, and the wins count is zero for both. However, the available specification data and the AMD part's recorded scores allow for a comparative analysis.

The AMD Radeon 740M has two recorded benchmark scores. In Geekbench OpenCL, it scores 10172. In Geekbench Vulkan, it scores 15568. These combine to an average of 12870.

The Intel Arc Pro B390 has no recorded scores in any test. The database lists its percentile versus all GPUs at 50, but this is based on no measurements and cannot be interpreted as a performance position.

In the absence of direct measurements, the specification differences indicate the Intel B390 holds a theoretical advantage in raw throughput. Its FP32 output of 7.680 TFLOPS is roughly 2.7 times the AMD part's 2.867 TFLOPS. Its pixel rate of 60.00 GPixel/s is 2.68 times the AMD part's 22.40 GPixel/s. Its texture rate of 120.0 GTexel/s is 2.68 times the AMD part's 44.80 GTexel/s. Its FP16 output of 15.36 TFLOPS is 5.36 times the AMD part's 2.867 TFLOPS, though the AMD part uses a 1:1 ratio while the Intel part uses a 2:1 ratio.

The AMD Radeon 740M's nearest rivals in the database are all discrete cards. It sits 0.2% ahead of the AMD FirePro W5100, 0.3% ahead of the AMD Radeon Pro 455, 0.3% ahead of the NVIDIA GeForce GTX 590, and 0.4% behind the AMD Radeon RX 580. These margins are small, placing the 740M in a performance band comparable to older discrete GPUs.

The Intel Arc Pro B390 has no such comparison data. Its higher specification counts do not translate to confirmed benchmark positions. The recorded data shows that the AMD 740M is a functional, measured part with verified performance, while the Intel B390 is an unmeasured part with higher theoretical specifications.

For Vulkan specifically, the AMD 740M's score of 15568 is 53% higher than its OpenCL score of 10172, suggesting the RDNA 3.0 architecture responds well to the Vulkan API. The Intel B390's API support matches (both support Vulkan 1.4), but no comparable scores exist.

The average benchmark score of 12870 for the AMD 740M places it at the 53rd percentile of all GPUs in the database. The Intel B390's 50th percentile is a placeholder value, not a measured outcome.

Given the absence of head-to-head data, the only quantitative comparison comes from the specification sheet. The Intel B390 has higher counts in every computational unit category, higher pixel throughput, higher texture throughput, and higher floating-point performance. The AMD 740M has a higher boost clock (2800 MHz versus 2500 MHz), a lower TDP (45 W versus 80 W), and verified benchmark scores.

The data indicates that the Intel Arc Pro B390 is architecturally positioned to deliver more raw compute, but the database has no recorded evidence of that performance. The AMD Radeon 740M is the only part with a demonstrated benchmark record, and that record places it in a competitive band with the AMD FirePro W5100, AMD Radeon Pro 455, NVIDIA GeForce GTX 590, and AMD Radeon RX 580.
