Intel Arc A310E vs Intel Arc Pro B50 Comparison

Head-to-Head Benchmarks

The Intel Arc Pro B50 is the dominant performer in every measurable category. The recorded data shows no benchmark results for the Intel Arc A310E, meaning the comparison is defined entirely by the Pro B50's absolute scores. The Pro B50 achieves an average benchmark score of 2660, while the A310E registers zero recorded measurements. This places the A310E at the 50th percentile of all GPUs in the database, while the Pro B50 sits at the 17th percentile. The percentile difference appears counterintuitive at first, but the percentile reflects the distribution of all recorded GPUs, not the head-to-head comparison.

The Pro B50 delivers 10.65 TFLOPS of FP32 compute, which is more than three times the A310E's 3.072 TFLOPS. In FP16, the Pro B50 reaches 21.30 TFLOPS versus 6.144 TFLOPS on the A310E, both using a 2:1 ratio. The texture rate gap is even more pronounced: 332.8 GTexel/s on the Pro B50 versus 64.00 GTexel/s on the A310E. Pixel rate also favors the Pro B50 at 41.60 GPixel/s, compared to 32.00 GPixel/s on the A310E.

Memory bandwidth tells a similar story. The Pro B50 uses a 128-bit bus with 224.0 GB/s of bandwidth, while the A310E is limited to a 64-bit bus and 124.0 GB/s. The Pro B50's 16 GB of GDDR6 memory dwarfs the A310E's 4 GB. In raw capacity terms, that is a fourfold difference that directly impacts workloads with large data sets, such as rendering scenes or compute buffers.

The nearest rivals for the Pro B50 provide context for its average score. The NVIDIA GeForce GT 1030 scores 2662, which is 0.1% higher than the Pro B50. The NVIDIA Quadro K1100M scores 2664, 0.2% higher. The NVIDIA GeForce GT 440 scores 2645, which is 0.6% lower. The NVIDIA GeForce RTX 5070 SUPER scores 2690, 1.1% higher. These deltas show the Pro B50's average benchmark score sits in a tight cluster around 2660, with no rival exceeding it by more than 1.1%. The A310E has no recorded rivals, no average score, and no percentile beyond its 50th placement, which is a neutral midpoint value.

Where Each One Wins

The Intel Arc Pro B50 wins in every category where data exists. The A310E has no recorded benchmark victories, no average score, and no head-to-head wins in the database. The Pro B50's wins are absolute across compute, memory, and graphics throughput.

The Pro B50's FP32 performance of 10.65 TFLOPS makes it suitable for general compute tasks that rely on single-precision floating point. Its FP16 output of 21.30 TFLOPS doubles the FP32 figure, which benefits workloads that can use reduced precision. The A310E's 3.072 TFLOPS FP32 and 6.144 TFLOPS FP16 place it in a lower performance tier, suitable for lighter graphics workloads but not competitive for heavy compute.

Memory capacity and bandwidth favor the Pro B50 decisively. The 16 GB frame buffer with 224.0 GB/s bandwidth supports larger textures, bigger geometry buffers, and more complex scenes than the A310E's 4 GB and 124.0 GB/s. In professional rendering or GPU compute contexts, the Pro B50's memory subsystem is the clear advantage.

The Pro B50 also leads in texture throughput with 128 TMUs versus 32 on the A310E, and in ray tracing with 16 RT cores versus 6. The A310E matches the Pro B50 in ROPs at 16, so pixel output per ROP is identical, but the Pro B50's higher pixel rate comes from its higher clock behavior. The Pro B50 boosts to 2600 MHz while the A310E holds a constant 2000 MHz for both base and boost.

Architecture Differences

The two GPUs come from different Intel architectures. The A310E uses the DG2-128 chip based on Xe-HPG, which belongs to the Alchemist generation under the Arc 3 branding. The Pro B50 uses the BMG-G21 chip based on Xe2-HPG, which belongs to the Battlemage generation under the Pro Series branding.

The manufacturing process differs as well. The A310E is built on TSMC's 6 nm node, while the Pro B50 uses TSMC's 5 nm node. The transistor counts reflect the architectural leap: the A310E packs 7,200 million transistors on a 157 mm² die, giving a density of 45.9 million transistors per square millimeter. The Pro B50 contains 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per square millimeter. The Pro B50's newer node and larger die allow nearly three times the transistor count.

Core configurations diverge sharply. The A310E has 768 shading units, 32 TMUs, and 16 ROPs. The Pro B50 has 2048 shading units, 128 TMUs, and 16 ROPs. The Pro B50's shading unit count is 2.67 times higher, and its TMU count is four times higher. Both GPUs have 16 ROPs, so the raster output stage is identical in unit count.

Ray tracing hardware differs: the A310E has 6 RT cores, while the Pro B50 has 16. Neither GPU lists tensor cores in the database. The Pro B50's RT core count is more than double, which suggests better ray tracing throughput per cycle, though the database provides no direct RT benchmark scores.

The memory architecture changes between generations. The A310E uses a 64-bit memory bus with 4 GB of GDDR6. The Pro B50 uses a 128-bit bus with 16 GB of GDDR6. The effective memory clock also differs: the A310E runs at 15.5 Gbps effective, while the Pro B50 runs at 14 Gbps effective. The Pro B50's wider bus more than compensates for its slightly lower memory clock, resulting in 224.0 GB/s versus 124.0 GB/s.

Display outputs advance from mini-DisplayPort 2.0 on the A310E to mini-DisplayPort 2.1 on the Pro B50. Both support four outputs. The bus interface changes from PCIe 4.0 x8 on the A310E to PCIe 5.0 x8 on the Pro B50, doubling the per-lane bandwidth available to the host system.

Specification Differences

The power profile is close but not identical. The A310E has a TDP of 75 W, while the Pro B50 has a TDP of 70 W. Both require a 250 W suggested power supply, and both draw power exclusively from the PCIe slot with no external power connectors. The Pro B50 delivers higher performance at 5 W lower TDP, which indicates a significant efficiency gain from the newer architecture and process node.

Physical dimensions differ in width only. Both cards are 168 mm or 6.6 inches long for the A310E, and 167 mm or 6.6 inches for the Pro B50. Both are 69 mm or 2.7 inches tall. The A310E is 20 mm or 0.8 inches wide and single-slot. The Pro B50 is 40 mm or 1.6 inches wide and dual-slot. The Pro B50's extra width accommodates a larger cooler, necessary for its higher core count despite the similar TDP.

Clock behavior diverges. The A310E runs at a fixed 2000 MHz for both base and boost. The Pro B50 has a 1700 MHz base clock and a 2600 MHz boost clock, a 900 MHz range that allows the card to scale down at idle and scale up under load. The Pro B50's boost clock is 30% higher than the A310E's constant clock.

The production status differs. The A310E is end-of-life, while the Pro B50 is active. The release dates are March 31, 2024 for the A310E and September 4, 2025 for the Pro B50. The A310E lists its predecessor as Xe Graphics and its successor as Battlemage, which is the architecture the Pro B50 uses. The Pro B50 has no predecessor or successor recorded in the database.

The Pro B50 has a launch MSRP of 349 USD. The A310E has no launch MSRP recorded. API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data supports a clear choice for any workload that requires measurable performance: the Intel Arc Pro B50. It wins every recorded benchmark category, has a significantly higher transistor count, more memory, higher bandwidth, more shading units, more TMUs, more RT cores, and a higher boost clock than the Intel Arc A310E. The Pro B50 achieves this with a lower TDP of 70 W versus 75 W on the A310E, and it remains an active production part while the A310E is end-of-life.

The Intel Arc A310E should be selected only in scenarios where the single-slot form factor is mandatory. At 20 mm wide versus 40 mm for the Pro B50, the A310E fits in chassis or adjacent-slot configurations where the dual-slot Pro B50 cannot. Its fixed 2000 MHz clock simplifies thermal management, and its 75 W TDP is nearly identical to the Pro B50's 70 W. But for any performance comparison, the A310E has no recorded data to support a win.

The Pro B50's nearest rival data shows it performs within 1.1% of the NVIDIA GeForce RTX 5070 SUPER in average benchmark score, and within 0.2% of the Quadro K1100M. This places the Pro B50 in a competitive performance band against those GPUs. The A310E has no such reference points. The Pro B50's 16 GB memory capacity and 224.0 GB/s bandwidth make it the only sensible choice for memory-intensive tasks, and its 2048 shading units provide the compute headroom that the A310E lacks.

The verdict from the recorded data is unambiguous. The Intel Arc Pro B50 is the superior GPU in compute, memory, ray tracing, and efficiency. The Intel Arc A310E is a legacy part with no benchmark presence, suited only for constrained physical installations where its single-slot width is the deciding factor.
