AMD Radeon 740M vs Intel Arc Pro B70 Comparison

AMD Radeon 740M and Intel Arc Pro B70 occupy very different positions in the GPU landscape. The Radeon 740M is an integrated graphics processor designed for thin and light laptops, while the Arc Pro B70 is a large discrete workstation card. The recorded data shows a clear separation in raw compute capability, memory subsystem, and physical design, with the Arc Pro B70 delivering roughly eight times the FP32 throughput of the Radeon 740M.

Head-to-Head Benchmarks

Direct head-to-head benchmark results between the AMD Radeon 740M and the Intel Arc Pro B70 are not present in the database. The Arc Pro B70 has no recorded benchmark scores, showing an average benchmark score of zero, and its percentile ranking against all GPUs sits at 50. The Radeon 740M, by contrast, has two recorded benchmark submissions: a Geekbench OpenCL score of 10172 and a Geekbench Vulkan score of 15568. These two results produce an average benchmark score of 12870 for the Radeon 740M.

Without a shared test suite, the comparison relies on each product's position relative to other hardware. The Radeon 740M ranks in the 53rd percentile among all GPUs in the database. Its nearest rivals include the AMD FirePro W5100, which averages 12847 points, a margin of 0.2 percent. The AMD Radeon Pro 455 averages 12831 points, also 0.3 percent behind. The NVIDIA GeForce GTX 590 averages 12830 points, another 0.3 percent gap. The only rival ahead of the 740M is the AMD Radeon RX 580, which averages 12928 points, or 0.4 percent faster. These figures place the 740M in a tightly packed cluster of mid-range GPUs from several generations ago, with all four nearest rivals within a one-point margin of each other in percentage terms.

The Arc Pro B70 has no rival list in the database and no benchmark scores to place it within this hierarchy. Its 50th percentile ranking suggests it sits near the median of all recorded GPUs, but the absence of measured results means the database cannot confirm its relative standing against the 740M or any other product. The data indicates that the 740M's Vulkan score of 15568 is substantially higher than its OpenCL score of 10172, a 53 percent advantage within the same GPU. This gap between API results is common in integrated graphics and reflects driver optimization differences rather than a fundamental hardware limitation.

The FP32 compute figures provide the clearest numerical separation. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 performance, while the Radeon 740M delivers 2.867 TFLOPS. That places the Arc Pro B70 at exactly 8.0 times the FP32 throughput of the 740M. The FP16 comparison is even more lopsided. The Arc Pro B70 reaches 45.88 TFLOPS of FP16 performance, using a 2:1 ratio relative to FP32, while the 740M achieves only 2.867 TFLOPS of FP16, at a 1:1 ratio. The Arc Pro B70 therefore provides 16.0 times the FP16 throughput of the 740M.

Pixel and texture rates follow the same pattern. The Arc Pro B70 renders 358.4 GPixel/s, compared to 22.40 GPixel/s for the 740M, a 16.0 times difference. Texture fill rates measure 716.8 GTexel/s for the Arc Pro B70 versus 44.80 GTexel/s for the 740M, again a 16.0 times gap. These ratios align with the hardware count differences: the Arc Pro B70 has 16 times the texture mapping units and 16 times the render output units of the 740M.

Architecture Differences

The two GPUs come from different architectural families and process nodes. The Radeon 740M uses the Phoenix2 chip, built on RDNA 3.0 architecture, and belongs to the Navi III IGP generation. It is manufactured on a 4 nm process at TSMC, with 20,900 million transistors packed into a 137 mm² die. The transistor density calculates to 152.6 million transistors per square millimeter. The Intel Arc Pro B70 uses the BMG-G31 chip, built on Xe2-HPG architecture, and belongs to the Battlemage Pro Series generation. It is manufactured on a 5 nm process at TSMC, with a die size of 368 mm². The transistor count for the Arc Pro B70 is recorded as unknown in the database, and no transistor density figure is available.

The compute unit counts reflect the architectural differences. The Radeon 740M contains 256 shading units, 16 texture mapping units, 8 render output units, and 4 ray tracing cores. The Arc Pro B70 contains 4096 shading units, 256 texture mapping units, 128 render output units, and 32 ray tracing cores. In every category, the Arc Pro B70 has exactly 16 times the resources of the 740M. Neither GPU has tensor cores listed in the database.

Clock behavior differs as well. The Radeon 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The Arc Pro B70 has a base clock of 2280 MHz and the same 2800 MHz boost clock. The Arc Pro B70's base clock runs 185 percent higher than the 740M's base clock, though both reach the same boost ceiling. The Arc Pro B70 also has a memory clock of 2375 MHz, listed as 19 Gbps effective, while the 740M's memory clock is listed as System Shared.

The memory architecture could not be more different. The Radeon 740M uses system shared memory, with no dedicated VRAM, no dedicated memory bus width, and bandwidth described as System Dependent. The Arc Pro B70 ships with 32 GB of GDDR6 memory on a 256 bit bus, delivering 608.0 GB/s of bandwidth. This dedicated memory arrangement gives the Arc Pro B70 a fully isolated memory subsystem, whereas the 740M must share bandwidth and capacity with the host CPU.

API support is identical across both products. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power and physical requirements diverge sharply. The Radeon 740M carries a 45 W TDP, uses an IGP slot width, requires no power connectors, and connects via PCIe 4.0 x8. The Arc Pro B70 carries a 230 W TDP, uses a dual-slot design, requires a single 8-pin power connector, suggests a 550 W power supply, and connects via PCIe 5.0 x16. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width, while the 740M has no recorded dimensions because it is an integrated part.

Display output capabilities also differ. The 740M's display outputs are motherboard dependent, since it is an integrated GPU. The Arc Pro B70 provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The production status of the 740M is Active, while the Arc Pro B70 has no production status recorded.

The Verdict

The data supports a straightforward selection based on workload requirements. The AMD Radeon 740M is an integrated GPU with a 45 W TDP, system shared memory, and a 53rd percentile ranking among all GPUs. Its recorded benchmark scores of 10172 in OpenCL and 15568 in Vulkan place it within 0.4 percent of several established discrete GPUs like the Radeon RX 580, which scores 12928. The 740M suits systems where power draw, physical space, and cost are constrained, and where the host system's memory bandwidth is sufficient for the intended tasks.

The Intel Arc Pro B70 targets a different segment entirely. Its 32 GB of GDDR6 memory with 608.0 GB/s of bandwidth, 4096 shading units, and 22.94 TFLOPS of FP32 performance position it for memory-intensive and compute-heavy workloads. The 230 W TDP, dual-slot cooler, 550 W suggested power supply, and 267 mm length require a full desktop platform with adequate cooling and power delivery. The 16 times advantage in texture mapping units, render output units, shading units, and ray tracing cores over the 740M gives it a decisive edge in any workload that scales with parallel compute resources.

The 50th percentile ranking for the Arc Pro B70, combined with its lack of recorded benchmark scores, means the database cannot confirm its real-world standing. The 740M's 53rd percentile ranking, by contrast, is backed by measured results. Users who need a proven, low-power integrated solution with documented performance should consider the 740M. Users who need maximum compute throughput, dedicated memory capacity, and workstation display outputs should consider the Arc Pro B70, provided the platform can support its power and physical requirements. The 16 times difference in FP16 performance, which reaches 45.88 TFLOPS on the Arc Pro B70, makes that card the only choice for FP16-heavy workflows. The 740M's 1:1 FP16 ratio and 2.867 TFLOPS ceiling cannot approach that level of throughput. The choice rests on whether the workload demands the Arc Pro B70's dedicated memory and compute scale or whether the 740M's integrated efficiency and documented benchmark results are sufficient.
