AMD Radeon 740M vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The database records only one benchmark suite for the AMD Radeon 740M, with no direct comparison scores for the Intel Arc A380E x2. The Radeon 740M delivers a Geekbench OpenCL score of 10,172 and a Geekbench Vulkan score of 15,568. Its average benchmark score across recorded tests stands at 12,870. The Intel Arc A380E x2 has no recorded benchmark scores in the database, leaving its average at zero and its percentile at 50, which places it in the lower half of all GPUs. The Radeon 740M sits at the 53rd percentile, indicating it outperforms slightly more than half of all recorded GPUs.

The nearest rivals for the Radeon 740M provide context for its average score. The AMD Radeon RX 580 scores 12,928, which is 0.4% higher than the 740M's average, making it the closest competitor in the recorded data. The AMD FirePro W5100 scores 12,847, a 0.2% deficit relative to the 740M. The AMD Radeon Pro 455 scores 12,831, also 0.3% behind. The NVIDIA GeForce GTX 590 scores 12,830, matching the Pro 455's 0.3% gap. These margins are extremely tight, with the entire spread from the GTX 590 to the RX 580 covering less than 1%. The data suggests the 740M performs in a narrow band around 12,800 to 12,900 in average benchmark terms, with no single rival establishing a clear lead.

The raw compute specifications show a substantial theoretical gap between the two products, but without benchmark results for the Intel part, the measured performance cannot be directly compared. The Radeon 740M delivers 2.867 TFLOPS FP32 and 2.867 TFLOPS FP16 at a 1:1 ratio. The Arc A380E x2 delivers 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16 at a 2:1 ratio. The Intel part's FP16 throughput is nearly triple the AMD part's, and its FP32 output is roughly 43% higher. Pixel rate for the Intel part is 64.00 GPixel/s versus 22.40 GPixel/s for the AMD part, a 2.86x advantage. Texture rate shows 128.0 GTexel/s versus 44.80 GTexel/s, a 2.86x advantage as well. These figures indicate the Intel product has a significantly higher theoretical ceiling, but the absence of recorded benchmark data means the actual realized performance remains unverified in the database.

Where Each One Wins

The AMD Radeon 740M wins in the only measured category: recorded benchmark scores. Its Geekbench Vulkan result of 15,568 is notably higher than its OpenCL result of 10,172, suggesting the Vulkan API path delivers stronger performance for this IGP. The average of 12,870 places it just ahead of the FirePro W5100 and Radeon Pro 455 in the nearest rival list. The 740M also wins on efficiency metrics derived from its specifications. It carries a TDP of 45 W, uses no power connectors, and occupies an IGP slot width, meaning it draws power through the motherboard and requires no additional cooling or power supply headroom. The process node is 4 nm at TSMC, which is smaller than the Intel part's 6 nm node. Transistor density reinforces this: the 740M packs 152.6 million transistors per square millimeter versus 45.9 million for the Intel part, a 3.3x density advantage. The die size is smaller as well at 137 mm² versus 157 mm², while the transistor count is higher at 20,900 million versus 7,200 million. This indicates the AMD chip achieves more transistors in less silicon area.

The Intel Arc A380E x2 wins on raw specification headroom across nearly every compute metric. Its 1024 shading units compare to 256 for the AMD part, a 4x difference. Texture mapping units number 64 versus 16, and raster operation units number 32 versus 8. Ray tracing cores double the AMD count at 8 versus 4. Memory bandwidth is a decisive advantage: the Intel part has 6 GB of GDDR6 on a 96-bit bus delivering 186.0 GB/s, while the AMD part uses system shared memory with bandwidth listed as system dependent. The Intel product also has a fixed memory clock of 1937 MHz with 15.5 Gbps effective transfer, whereas the AMD part's memory clock is system shared. The Intel card offers 8x mini-DisplayPort 2.0 outputs, while the AMD IGP's display outputs are motherboard dependent. The Intel part is a single-slot card with a 1x 6-pin power connector and a suggested PSU of 300 W, indicating it is designed as a standalone add-in board rather than an integrated solution.

The use-case split is clear from the data. The AMD Radeon 740M suits systems where integration and low power draw are priorities, given its 45 W TDP, lack of external power connectors, and IGP form factor. The Intel Arc A380E x2 suits systems requiring dedicated memory bandwidth and higher compute throughput, evidenced by its 186.0 GB/s bandwidth and 130 W TDP. The Intel part's 8x mini-DisplayPort 2.0 outputs suggest multi-display or embedded applications, while the AMD part's motherboard dependent outputs tie it to laptop or compact desktop designs.

The Verdict

The data supports a clear division of roles. The AMD Radeon 740M is the choice for integrated graphics workloads where the measured benchmark scores matter. Its recorded average of 12,870 and 53rd percentile ranking demonstrate it performs competitively against discrete GPUs from several generations back, including the Radeon RX 580, which sits only 0.4% higher. For any system where a separate graphics card is undesirable, the 740M provides verified performance with a 45 W TDP and no power connector requirement.

The Intel Arc A380E x2 is the choice for workloads that demand the specifications listed in the database, despite having no recorded benchmark scores. The 4.096 TFLOPS FP32 throughput, 128.0 GTexel/s texture rate, and 64.00 GPixel/s pixel rate all exceed the AMD part's corresponding figures by wide margins. The dedicated 6 GB GDDR6 memory with 186.0 GB/s bandwidth removes dependence on system RAM performance. The 8 ray tracing cores and 1024 shading units provide a higher ceiling for compute-heavy tasks. Users who prioritize measured results over theoretical specifications would select the Radeon 740M. Users who require the higher raw throughput and dedicated memory would select the Intel Arc A380E x2, accepting that its performance has not been verified in the database.

The architectural comparison highlights several fundamental differences. The AMD part is an integrated GPU with system shared memory, a 45 W power envelope, and no external power requirement. The Intel part is a discrete single-slot card with dedicated GDDR6 memory, a 130 W power envelope, and a 6-pin connector. The transistor counts diverge sharply: the AMD chip has nearly three times the transistors of the Intel chip, yet occupies a smaller die. The Intel chip compensates with higher clock speeds, a fixed 2000 MHz versus the AMD part's 800 MHz base and 2800 MHz boost, and a much wider execution resource pool. The ray tracing core counts differ by a factor of two, with the Intel part at 8 and the AMD part at 4. The FP16 ratio also differs: the AMD part processes FP16 at the same rate as FP32, while the Intel part doubles FP16 throughput relative to FP32. The production statuses also differ, with the AMD part listed as active and the Intel part listed as end-of-life.
