AMD Radeon 740M vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the two products have asymmetric benchmark coverage. The AMD Radeon 740M has two recorded benchmark scores: 10,172 in Geekbench OpenCL and 15,568 in Geekbench Vulkan. Its average benchmark score across all recorded tests is 12,870. The Intel Arc A380E, by contrast, has no recorded benchmark scores in the database, and its average benchmark score is listed as 0. This makes a direct head-to-head comparison using identical test workloads impossible from the available data.

The AMD Radeon 740M occupies the 53rd percentile among all GPUs in the database. Its nearest rivals, based on average benchmark score, are clustered tightly around its result. The AMD FirePro W5100 scores 12,847, which is 0.2% behind the 740M. The AMD Radeon Pro 455 scores 12,831, 0.3% behind. The NVIDIA GeForce GTX 590 also scores 12,830, 0.3% behind. On the other side, the AMD Radeon RX 580 scores 12,928, which puts it 0.4% ahead of the 740M. This tight grouping indicates that the 740M sits in a crowded performance band where the differences between adjacent products are within measurement noise.

The Intel Arc A380E has a 50th percentile ranking among all GPUs, but with no recorded benchmark scores, this percentile is effectively a placeholder rather than a measured result. The database shows no head-to-head benchmark entries for these two products, and neither product records any wins in the head-to-head comparison. The absence of benchmark data for the A380E means that any quantitative performance comparison must rely on the architectural specifications rather than measured results.

Architecture Differences

The AMD Radeon 740M is built on the Phoenix2 chip using the RDNA 3.0 architecture, which places it in the Navi III IGP generation for Phoenix-based integrated graphics. It is manufactured on a 4 nm process at TSMC, with 20,900 million transistors packed into a 137 mm² die. This yields a transistor density of 152.6 million transistors per square millimeter. The integrated graphics processor uses a base clock of 800 MHz and a boost clock of 2800 MHz. Memory is system shared, meaning the GPU draws from the host system's main memory, with bandwidth described as system dependent.

The Intel Arc A380E uses the DG2-128 chip with the Xe-HPG architecture, belonging to the Alchemist generation within the Arc 3 product line. It is manufactured on a 6 nm process, also at TSMC, with 7,200 million transistors on a 157 mm² die. The transistor density is 45.9 million transistors per square millimeter, significantly lower than the AMD part due to the older process node. The A380E runs at a fixed 2000 MHz clock for both base and boost, and it has dedicated GDDR6 memory: 6 GB on a 96-bit bus, with a memory clock of 1937 MHz or 15.5 Gbps effective, producing 186.0 GB/s of bandwidth.

The compute units differ substantially. The Radeon 740M has 256 shading units, 16 texture mapping units, and 8 render output units. It includes 4 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, and 32 ROPs, with 8 ray tracing cores. The Intel part has four times the shading units, four times the TMUs, four times the ROPs, and twice the ray tracing cores compared to the AMD integrated solution.

The pixel and texture rates reflect these differences. The 740M delivers 22.40 GPixel/s and 44.80 GTexel/s. The A380E delivers 64.00 GPixel/s and 128.0 GTexel/s. In floating point performance, the 740M achieves 2.867 TFLOPS for FP32 and the same 2.867 TFLOPS for FP16, indicating a 1:1 ratio. The A380E achieves 4.096 TFLOPS for FP32 and 8.192 TFLOPS for FP16, showing a 2:1 ratio where FP16 throughput is double FP32.

Both products support the same API feature set: DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x8 bus interface. The power characteristics differ notably. The 740M has a 45 W TDP and is an integrated graphics processor with no power connectors and no slot width. The A380E has a 75 W TDP, is a single-slot card, requires no power connectors, and has a suggested PSU rating of 250 W. The A380E measures 254 mm in length, 127 mm in height, and 20 mm in width.

The Verdict

The data indicates two products aimed at fundamentally different use cases. The AMD Radeon 740M is an integrated graphics processor with a 45 W TDP, designed to share system memory and operate within a host platform. Its recorded benchmark scores place it in the 53rd percentile, with performance tightly clustered around rivals like the AMD FirePro W5100 and the NVIDIA GeForce GTX 590, all within 0.3% of each other. The measured average benchmark score of 12,870 gives it a concrete performance reference point.

The Intel Arc A380E is a discrete, single-slot card with 6 GB of dedicated GDDR6 memory, a 75 W TDP, and a suggested PSU of 250 W. Its architectural specifications are substantially higher in most compute metrics: 4.096 TFLOPS FP32 versus 2.867 TFLOPS, 1024 shading units versus 256, and 186.0 GB/s of dedicated bandwidth versus system-dependent shared memory. The pixel rate of 64.00 GPixel/s is nearly three times the 740M's 22.40 GPixel/s, and the texture rate of 128.0 GTexel/s is nearly three times the 44.80 GTexel/s.

However, the A380E has no recorded benchmark scores, making its real-world performance unverified in the database. Its production status is end-of-life, while the 740M remains active. The A380E also carries a 254 mm board length and requires a 250 W PSU recommendation, whereas the 740M has no physical dimensions or PSU requirement because it integrates into a motherboard.

From the recorded data, the AMD Radeon 740M is the only product with verified performance measurements. Its tight clustering with the Radeon RX 580, which sits only 0.4% ahead, and the FirePro W5100, Radeon Pro 455, and GTX 590, which sit 0.2% to 0.3% behind, indicates a well-established performance level. The Intel Arc A380E, based on specifications alone, should deliver higher compute throughput, but the database contains no measurements to confirm this. The A380E's higher TDP, dedicated memory, and larger physical footprint suggest it targets systems that can accommodate a discrete card, while the 740M targets compact or integrated platforms. The choice between them, based strictly on data, depends on whether verified benchmark results or higher theoretical specifications take priority.
