AMD Radeon 740M vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded database contains two benchmark entries for the AMD Radeon 740M: a Geekbench OpenCL score of 10,172 and a Geekbench Vulkan score of 15,568. These results combine into an average benchmark score of 12,870, placing the Radeon 740M at the 53rd percentile among all GPUs in the database.

The Intel Arc Pro B65 has no recorded benchmark results. Its average benchmark score is listed as 0, and it holds the 50th percentile based on specifications alone. The head-to-head comparison table is empty, meaning no direct benchmark match exists between these two parts.

For context on the Radeon 740M's standing, the nearest rivals in the database show tight clustering. The AMD FirePro W5100 posts an average score of 12,847, which is 0.2% behind the 740M. The AMD Radeon Pro 455 scores 12,831, also 0.3% behind. The NVIDIA GeForce GTX 590 matches at 12,830, another 0.3% deficit. The AMD Radeon RX 580 leads slightly with 12,928, a 0.4% advantage over the 740M.

These deltas are remarkably small. The entire spread between the RX 580 at the top and the GTX 590 at the bottom covers less than one percent. The data indicates the Radeon 740M sits in a performance band where rival products are effectively indistinguishable from one another in aggregate scoring.

Without any benchmark entries for the Arc Pro B65, the quantitative comparison rests entirely on the Radeon 740M's measured results and the architectural specifications of both products. The Arc Pro B65's average score of 0 reflects the absence of tested data, not a performance value.

Architecture Differences

The two GPUs come from different manufacturers and use different process technologies. The AMD Radeon 740M uses the Phoenix2 chip built on RDNA 3.0 architecture, produced on a 4 nm process at TSMC. The Intel Arc Pro B65 uses the BMG-G21 chip built on Xe2-HPG architecture, produced on a 5 nm process, also at TSMC.

Transistor counts are similar, with the Radeon 740M carrying 20,900 million transistors and the Arc Pro B65 carrying 19,600 million. Die sizes diverge significantly: the Radeon 740M measures 137 mm², while the Arc Pro B65 measures 272 mm². This produces a transistor density of 152.6 million transistors per square millimeter for the AMD part versus 72.1 million for the Intel part, meaning the Radeon 740M packs roughly twice the transistor density despite having more total transistors.

Clock behavior differs sharply. The Radeon 740M has an 800 MHz base clock and a 2,800 MHz boost clock, allowing dynamic frequency scaling. The Arc Pro B65 runs at a fixed 2,400 MHz for both base and boost, with no boost headroom.

Memory subsystems are entirely different classes. The Radeon 740M uses system shared memory with system dependent bandwidth, typical of an integrated GPU. The Arc Pro B65 carries 32 GB of dedicated GDDR6 memory on a 256-bit bus, delivering 608.0 GB/s of bandwidth. The memory clock for the Intel part is 2,375 MHz with 19 Gbps effective data rate.

Compute resources show a large gap. The Radeon 740M has 256 shading units, 16 texture mapping units, 8 render output units, and 4 ray tracing cores. The Arc Pro B65 has 2,560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. The Intel part has ten times the shading units, ten times the TMUs, ten times the ROPs, and five times the ray tracing cores.

Pixel and texture throughput follow the same pattern. The Radeon 740M delivers 22.40 GPixel/s and 44.80 GTexel/s. The Arc Pro B65 delivers 192.0 GPixel/s and 384.0 GTexel/s, representing roughly 8.6 times the pixel rate and 8.6 times the texture rate.

Floating point performance differs substantially. The Radeon 740M reaches 2.867 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The Arc Pro B65 reaches 12.29 TFLOPS for FP32 and 24.58 TFLOPS for FP16, a 2:1 ratio. The Intel part offers 4.3 times the FP32 throughput and 8.6 times the FP16 throughput.

Power envelopes contrast strongly. The Radeon 740M has a 45 W TDP and requires no power connectors, consistent with an integrated graphics solution. The Arc Pro B65 has a 200 W TDP, uses a single 8-pin power connector, and suggests a 550 W power supply. The Intel card occupies a dual-slot form factor, while the AMD part is an IGP with motherboard dependent display outputs.

Bus interfaces differ as well. The Radeon 740M uses PCIe 4.0 x8, while the Arc Pro B65 uses PCIe 5.0 x16. Display outputs on the Intel card are four DisplayPort 2.1 connections; the AMD card's outputs depend on the motherboard.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates are separated by roughly two years: the Radeon 740M launched on 2024-01-30, and the Arc Pro B65 launched on 2026-03-31.

Where Each One Wins

The Radeon 740M wins in efficiency metrics. Its 45 W TDP is dramatically lower than the Arc Pro B65's 200 W. It requires no power connectors, occupies no expansion slot as an IGP, and fits into systems with motherboard dependent display connectivity. The 4 nm process node delivers a higher transistor density, and the smaller die size of 137 mm² indicates a more compact implementation.

The Radeon 740M also wins in clock flexibility. Its boost clock of 2,800 MHz is 400 MHz above the Intel part's fixed 2,400 MHz, allowing the AMD GPU to scale frequency dynamically under thermal headroom. The base clock of 800 MHz suggests aggressive idle and low-load power saving capability.

The Arc Pro B65 wins in raw compute throughput. Its 2,560 shading units, 160 TMUs, and 80 ROPs provide roughly ten times the parallel execution resources of the Radeon 740M. FP32 performance of 12.29 TFLOPS is 4.3 times higher, and FP16 performance of 24.58 TFLOPS is 8.6 times higher.

The Arc Pro B65 wins in memory capacity and bandwidth. The 32 GB GDDR6 pool with 608.0 GB/s bandwidth is a dedicated, high-speed configuration, while the Radeon 740M depends on system memory with bandwidth that varies by platform. The 256-bit bus provides a wide data path that the Radeon 740M cannot match.

The Arc Pro B65 wins in ray tracing resources with 20 ray tracing cores versus 4 on the AMD part. It also wins in display output capabilities with four dedicated DisplayPort 2.1 connections, and in bus bandwidth with PCIe 5.0 x16 versus PCIe 4.0 x8.

The measured benchmark data only covers the Radeon 740M, so the performance comparison relies on the specification deltas. The Radeon 740M's 53rd percentile rank places it just above the midpoint of all GPUs in the database, while the Arc Pro B65's 50th percentile is an unverified placeholder pending benchmark results.

The Verdict

The data presents two GPUs aimed at different roles. The AMD Radeon 740M is an integrated graphics solution with a 45 W TDP, no power connectors, and system shared memory. Its measured average benchmark score of 12,870 places it in the 53rd percentile, with nearest rivals all within 0.4% of its aggregate performance. The tight clustering around the 740M's score indicates that this performance band is crowded with comparable parts from both AMD and NVIDIA.

The Intel Arc Pro B65 is a discrete workstation card with 32 GB of GDDR6 memory, a 256-bit bus, 608.0 GB/s bandwidth, and a 200 W TDP requiring a single 8-pin connector and a 550 W power supply. Its 2,560 shading units and 12.29 TFLOPS FP32 throughput suggest a substantially higher compute ceiling than the Radeon 740M's 256 shading units and 2.867 TFLOPS. The 4.3 times FP32 advantage and 8.6 times FP16 advantage point toward workloads that scale with raw throughput.

The Radeon 740M suits systems where power draw, space, and simplicity matter. Its IGP form factor, motherboard dependent outputs, and system shared memory align with compact or low-power builds. The Arc Pro B65 suits environments requiring dedicated memory capacity, high bandwidth, and sustained compute throughput, with its dual-slot design and external power delivery indicating a larger thermal and electrical footprint.

The missing benchmark data for the Arc Pro B65 prevents a direct performance verdict. The specification differences, however, are unambiguous. The Radeon 740M wins on efficiency, density, and clock flexibility. The Arc Pro B65 wins on every throughput metric: shading units, TMUs, ROPs, ray tracing cores, pixel rate, texture rate, FP32, FP16, memory capacity, memory bandwidth, and bus width.

The release dates reinforce the generational gap. The Radeon 740M launched on 2024-01-30, and the Arc Pro B65 launched on 2026-03-31, with the Intel part arriving more than two years later. The Radeon 740M sits near the 53rd percentile against all GPUs, while the Arc Pro B65's 50th percentile is provisional until benchmark results populate the database.
