AMD Radeon 740M vs Intel Arc G3 Comparison

AMD Radeon 740M and Intel Arc G3 represent two distinct approaches to integrated graphics, with the data showing a clear performance gap in favor of Intel on paper. The Arc G3 delivers a computed FP32 throughput of 6.144 TFLOPS, more than double the 2.867 TFLOPS of the Radeon 740M. Texture and pixel fill rates also favor Intel: 96.00 GTexel/s versus 44.80 GTexel/s, and 48.00 GPixel/s versus 22.40 GPixel/s. These raw throughput figures suggest the Arc G3 has a substantial compute advantage, although its benchmark results are not yet recorded in the database, while the Radeon 740M has measured scores.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, so direct same-test comparisons are unavailable. Instead, the Radeon 740M has recorded two individual benchmark scores. In Geekbench OpenCL, it scores 10172, and in Geekbench Vulkan, it scores 15568. Its average benchmark score is 12870, which places it at the 53rd percentile among all GPUs. The Arc G3 currently has no benchmark entries, an average score of 0, and sits at the 50th percentile, which reflects its unmeasured status rather than a competitive ranking.

Without recorded scores for the Arc G3, the comparison relies on the computed specifications. The FP32 rate difference is the largest single gap: 6.144 TFLOPS versus 2.867 TFLOPS, a 2.14x advantage for Intel. The texture rate difference is similar in proportion, with the Arc G3 at 96.00 GTexel/s versus 44.80 GTexel/s. Pixel rate is 48.00 GPixel/s versus 22.40 GPixel/s. These margins indicate that in any compute-bound or fill-rate-bound workload where the architecture scales linearly, the Arc G3 should outperform the Radeon 740M by roughly 2x, assuming driver and memory performance do not bottleneck.

The Radeon 740M does hold one measurable edge: its nearest rival data provides context for its observed performance. It sits within 0.4% of the AMD Radeon RX 580, which has an average score of 12928, and within 0.3% of the NVIDIA GeForce GTX 590 at 12830. The Radeon 740M is 0.2% ahead of the AMD FirePro W5100 at 12847 and 0.3% ahead of the AMD Radeon Pro 455 at 12831. These deltas show the Radeon 740M performs at parity with a set of discrete GPUs from earlier generations, despite being an integrated part. The Arc G3 has no rival comparisons in the database, so its expected standing among known GPUs cannot be estimated from recorded measurements.

Architecture Differences

The two chips come from different foundries and nodes. The AMD Radeon 740M uses the Phoenix2 chip, built on RDNA 3.0 architecture, and is manufactured on a 4 nm process at TSMC. The Intel Arc G3 uses the Panther Lake chip, built on Xe3-LPG architecture, and is manufactured on a 3 nm process at Intel. The Radeon 740M has a declared transistor count of 20,900 million on a 137 mm² die, giving a transistor density of 152.6M / mm². The Arc G3 transistor count and die size are unknown in the database.

The execution resource counts differ sharply. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. The Radeon 740M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. Intel provides 5x the shading units, 2.5x the TMUs, 2.5x the ROPs, and 2.5x the ray tracing cores. Neither part includes tensor cores.

Clock behavior also differs. The Radeon 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The Radeon starts at a much higher base frequency, but the Arc G3 reaches a boost that is 400 MHz lower, yet still produces higher throughput because of its larger execution width.

The FP16 path is another architectural division. The Radeon 740M runs FP16 at 2.867 TFLOPS with a 1:1 ratio to FP32. The Arc G3 runs FP16 at 12.29 TFLOPS with a 2:1 ratio, meaning its FP16 rate is double its FP32 rate. This gives the Arc G3 a 4.29x advantage in FP16 throughput over the Radeon 740M, which could be significant for workloads that use packed math.

The memory subsystem is shared for both: system shared size, type, bus width, and bandwidth that is system dependent. The Radeon 740M connects via PCIe 4.0 x8, while the Arc G3 reports its bus interface as IGP. Both are integrated parts with no power connectors and a slot width of IGP. Display outputs are motherboard dependent for the Radeon 740M and portable device dependent for the Arc G3.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon 740M belongs to the Navi III IGP generation and lists its predecessor as Navi II IGP and successor as Navi III IGP. The Arc G3 belongs to the Arc Graphics-M (Panther Lake) generation with no predecessor or successor listed. The Radeon 740M was released on 2024-01-30, while the Arc G3 has a release date of 2026-05-31, over two years later.

Where Each One Wins

The Arc G3 wins on raw compute specifications. Its FP32 throughput of 6.144 TFLOPS is the strongest indicator of general compute performance. Its FP16 rate of 12.29 TFLOPS suggests particular strength in workloads that can use half-precision math. The 40 TMUs and 20 ROPs give it higher texture and pixel fill rates, which should help in rasterization-heavy scenes. The 10 ray tracing cores are 2.5x the count on the Radeon 740M, indicating better ray tracing capacity.

The Radeon 740M wins on measured evidence and maturity. Its benchmark scores are recorded: 10172 in Geekbench OpenCL and 15568 in Geekbench Vulkan, with an average of 12870. It has a higher base clock of 800 MHz versus 300 MHz, which could indicate better low-load responsiveness. Its 4 nm TSMC process with known transistor count and die size gives a complete manufacturing picture. The Radeon 740M also holds a 53rd percentile ranking against all GPUs, based on actual measurements, while the Arc G3 sits at the 50th percentile only because it has no data.

The power envelope is notable. The Arc G3 has a TDP of 25 W, while the Radeon 740M has a TDP of 45 W. This means the Arc G3 delivers higher computed throughput at a lower power limit, which is a significant efficiency indicator. The Radeon 740M requires 20 W more, based on the TDP figures, for roughly half the FP32 throughput.

The Verdict

The data points to the Intel Arc G3 as the stronger part on architectural grounds. It doubles the FP32 throughput, more than doubles the texture and pixel rates, carries 2.5x the ray tracing cores, and does so within a 25 W TDP, which is 20 W lower than the Radeon 740M. Its FP16 rate of 12.29 TFLOPS is over four times the Radeon 740M, and its 1280 shading units provide a massive execution width advantage. The 3 nm Intel process and newer release date also suggest a more recent design.

The AMD Radeon 740M is the only one of the two with measured results. Its performance is real and validated: it matches or slightly beats discrete GPUs like the AMD Radeon RX 580, NVIDIA GeForce GTX 590, AMD FirePro W5100, and AMD Radeon Pro 455, all within a 0.4% delta. That is a strong showing for an integrated GPU. The Arc G3 cannot claim any measured standing yet, as its benchmark array is empty and its percentile of 50 is a placeholder, not a performance figure.

For systems where verified performance matters, the Radeon 740M is the safer selection because its scores are recorded. For systems where maximum compute capability per watt is the priority, the specifications favor the Arc G3. The Radeon 740M also benefits from a higher base clock and a known manufacturing footprint, while the Arc G3 remains partially unspecified. The choice depends on whether the priority is validated, current performance or projected, higher-throughput architecture.
