AMD Radeon 780M vs Intel Arc A310E Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Radeon 780M and the Intel Arc A310E is limited by a significant gap in the recorded data. The AMD Radeon 780M has three benchmark entries in the database, while the Intel Arc A310E has none. This absence means the head-to-head table is empty, and the win count for each product stands at zero. The available measurements for the Radeon 780M, however, provide a basis for assessing its standing relative to the broader GPU landscape.

The Radeon 780M posts an average benchmark score of 17,588 across its recorded tests. Its individual results include 480 in 3DMark Steel Nomad (DX12), 18,602 in Geekbench OpenCL, and 33,683 in Geekbench Vulkan. The Vulkan result is particularly strong, indicating that the integrated graphics solution handles cross-platform graphics APIs with considerable efficiency. The OpenCL score reinforces this picture, showing solid general-purpose compute throughput. The 3DMark Steel Nomad score, while lower in absolute terms, reflects a demanding modern DX12 workload where the chip still delivers a usable result for an integrated part.

The nearest rivals for the Radeon 780M, based on average benchmark score, are instructive. The AMD Radeon Pro 560 sits 0.2% behind with an average score of 17,551, placing the two effectively at parity. The AMD Radeon Pro 460 trails by 0.5% with 17,509. On the other side, the NVIDIA GeForce RTX 4060 leads by 0.3% at 17,639, and the AMD Radeon HD 7790 leads by 0.4% at 17,666. These deltas are all within a single percentage point, which places the Radeon 780M in a tightly contested cluster. The data shows that the Radeon 780M performs in the same band as both older discrete cards and a modern desktop GPU, an impressive result for an integrated processor graphics solution with a 15 W TDP.

The Intel Arc A310E, by contrast, has no benchmark scores recorded in the database. Its percentile ranking versus all GPUs is 50, while the Radeon 780M sits at the 61st percentile. The absence of scores means no direct numerical comparison can be drawn for specific workloads. The Arc A310E does have a defined average benchmark score field, but it is zero, which reflects the lack of data rather than a measured performance of zero. Any analysis of the Arc A310E must therefore rely on its architectural and specification profile rather than empirical test results.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon 780M uses RDNA 3.0, built on the Phoenix chip, and belongs to the Navi III IGP (Phoenix) generation. It is manufactured on a 4 nm process at TSMC, with 25,390 million transistors packed into a 178 mm² die. That works out to a transistor density of 142.6 million transistors per square millimeter. The Intel Arc A310E uses Xe-HPG architecture, built on the DG2-128 chip, and belongs to the Alchemist (Arc 3) generation. It uses a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9 million per square millimeter. The Radeon 780M therefore packs nearly 3.5 times as many transistors onto a die that is only about 13% larger, a direct consequence of the denser manufacturing node.

The compute resources differ in several ways. Both parts have 768 shading units, but the Radeon 780M has 48 texture mapping units and 32 render output units, while the Arc A310E has 32 TMUs and 16 ROPs. The Radeon 780M also has 12 ray tracing cores, double the 6 found in the Arc A310E. The FP32 throughput reflects these differences: the Radeon 780M computes 8.909 TFLOPS, while the Arc A310E manages 3.072 TFLOPS. The FP16 picture is more nuanced. The Radeon 780M runs FP16 at 8.909 TFLOPS with a 1:1 ratio to FP32, while the Arc A310E reaches 6.144 TFLOPS with a 2:1 ratio, meaning it can perform twice as many FP16 operations as FP32 operations.

The memory architectures are fundamentally different. The Radeon 780M relies on system-shared memory, with its size, type, bus width, and bandwidth all determined by the host platform. The Arc A310E uses dedicated 4 GB of GDDR6 memory on a 64-bit bus, providing 124.0 GB/s of bandwidth. This distinction affects how each GPU accesses data, with the discrete memory on the Arc A310E offering predictable bandwidth while the Radeon 780M depends entirely on the system configuration.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the feature sets at the API level are equivalent. The Radeon 780M uses a PCIe 4.0 x8 interface, as does the Arc A310E.

Specification Differences

The specification sheets diverge across nearly every measurable category. The Radeon 780M has a base clock of 800 MHz and a boost clock of 2900 MHz, while the Arc A310E runs at a flat 2000 MHz for both base and boost. The Radeon 780M has no dedicated memory clock listed, as its memory is system-shared, while the Arc A310E has a memory clock of 1937 MHz with 15.5 Gbps effective.

Memory capacity and bandwidth separate the two clearly. The Radeon 780M has system-shared memory size and type, with system-dependent bandwidth. The Arc A310E has 4 GB of GDDR6, a 64-bit bus, and 124.0 GB/s of bandwidth. The Radeon 780M has 48 TMUs and 32 ROPs, while the Arc A310E has 32 TMUs and 16 ROPs. The Radeon 780M has 12 ray tracing cores, the Arc A310E has 6. The Radeon 780M delivers 8.909 TFLOPS of FP32 performance, the Arc A310E delivers 3.072 TFLOPS. The Radeon 780M has 8.909 TFLOPS of FP16 performance at a 1:1 ratio, the Arc A310E has 6.144 TFLOPS at a 2:1 ratio.

Pixel and texture rates also differ substantially. The Radeon 780M achieves 92.80 GPixel/s and 139.2 GTexel/s. The Arc A310E achieves 32.00 GPixel/s and 64.00 GTexel/s. The TDP is another major divider: the Radeon 780M is rated at 15 W, while the Arc A310E is rated at 75 W, with a suggested power supply of 250 W. The Radeon 780M is an IGP with no power connectors and motherboard-dependent display outputs. The Arc A310E is a single-slot card measuring 168 mm in length, 69 mm in height, and 20 mm in width, with no power connectors and four mini-DisplayPort 2.0 outputs.

The manufacturing details also differ. The Radeon 780M uses a 4 nm process with 25,390 million transistors on a 178 mm² die. The Arc A310E uses a 6 nm process with 7,200 million transistors on a 157 mm² die. The Radeon 780M was released on January 30, 2024, and remains active, with its predecessor listed as Navi II IGP and successor as Navi III IGP. The Arc A310E was released on March 31, 2024, and is end-of-life, with its predecessor listed as Xe Graphics and successor as Battlemage. The Radeon 780M occupies the 61st percentile among all GPUs, while the Arc A310E sits at the 50th percentile.

Where Each One Wins

The AMD Radeon 780M wins on raw compute performance in every measured category. Its FP32 throughput of 8.909 TFLOPS is nearly three times the 3.072 TFLOPS of the Arc A310E. Its pixel rate of 92.80 GPixel/s is roughly 2.9 times the 32.00 GPixel/s of the Arc A310E, and its texture rate of 139.2 GTexel/s is more than double the 64.00 GTexel/s of the Arc A310E. The ray tracing core count of 12 versus 6 further favors the Radeon 780M. Its 61st percentile ranking among all GPUs, compared to the 50th percentile for the Arc A310E, indicates a higher overall standing in the database.

The Radeon 780M also wins on efficiency. It delivers its substantially higher performance within a 15 W TDP, compared to the 75 W TDP of the Arc A310E. This makes the Radeon 780M suitable for systems where power draw is a primary constraint, such as thin-and-light laptops or compact integrated builds. Its transistor density of 142.6 million per square millimeter, versus 45.9 million for the Arc A310E, reflects a more advanced manufacturing process that enables both higher performance and lower power consumption.

The Intel Arc A310E wins on memory determinism. Its dedicated 4 GB of GDDR6 memory with 124.0 GB/s of bandwidth provides a fixed, guaranteed memory subsystem, whereas the Radeon 780M depends entirely on system-shared memory whose bandwidth can vary with the host platform. For workloads that are sensitive to memory bandwidth consistency, the Arc A310E offers a predictable baseline. The Arc A310E also has a higher memory clock at 1937 MHz, though this is a less meaningful comparison given the fundamental difference in memory architecture.

The Arc A310E's physical form factor is another differentiator. As a single-slot card with four mini-DisplayPort 2.0 outputs, it can serve as a dedicated display output solution in systems where motherboard outputs are insufficient. The Radeon 780M, being an IGP, has motherboard-dependent display outputs and cannot be installed as a discrete card. The Arc A310E's 168 mm length and 69 mm height make it a compact add-in card, though its 75 W TDP and 250 W suggested power supply requirement mean it needs a system with adequate power delivery headroom.

In terms of production lifecycle, the Radeon 780M is still active, while the Arc A310E is end-of-life. The recorded data shows the Radeon 780M as the stronger performer across compute metrics, with the Arc A310E offering the advantages of dedicated memory and a discrete card form factor. For scenarios where integrated graphics with high compute throughput and low power draw are priorities, the Radeon 780M is the clear choice. For systems requiring a standalone card with fixed memory bandwidth and multiple display outputs, the Arc A310E has structural advantages despite its lack of recorded benchmark scores.
