Intel Arc A310E vs Intel Arc Graphics 64EU Mobile Comparison

The Verdict

The Intel Arc A310E and the Intel Arc Graphics 64EU Mobile serve fundamentally different roles within Intel's graphics lineup, and the recorded data makes those roles clear. The Arc A310E is a discrete, single-slot desktop component built on the Xe-HPG architecture with a dedicated 4 GB GDDR6 memory subsystem. The Arc Graphics 64EU Mobile is an integrated graphics processor (IGP) embedded within the Meteor Lake chip, sharing system memory and relying on a Ring Bus interface. Benchmark results indicate that the discrete card holds a decisive advantage in raw compute throughput and memory bandwidth. The data shows the Arc A310E delivers approximately 71% higher FP32 performance and roughly 71% higher FP16 performance compared to the mobile integrated solution. For any workload that stresses graphics processing power, the Arc A310E is the clear choice based on specifications alone. The Arc Graphics 64EU Mobile, however, is the only option for portable devices where discrete graphics are not feasible, and its active production status suggests continued availability in that integrated role. Users seeking maximum performance from a small desktop card should select the Arc A310E, while those requiring an integrated solution for a laptop or compact portable system must rely on the 64EU Mobile part.

Architecture Differences

The two GPUs represent distinct architectural generations and manufacturing approaches. The Intel Arc A310E uses the DG2-128 chip built on the Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC, with a transistor count of 7,200 million packed into a die size of 157 mm². The transistor density measures 45.9 million transistors per square millimeter. The mobile part, the Intel Arc Graphics 64EU Mobile, uses the Meteor Lake chip with the Xe-LPG architecture, belonging to the Arc Graphics-M (Meteor Lake) generation. It is fabricated on a 10 nm process at Intel. Transistor count and die size for the mobile part are not recorded in the database. The Arc A310E features 768 shading units, 32 texture mapping units, and 16 raster output units, along with 6 ray tracing cores. The Arc Graphics 64EU Mobile has 512 shading units, 32 texture mapping units, and 16 raster output units, with no ray tracing cores listed. The core clock speeds differ substantially: the Arc A310E runs at a fixed 2000 MHz base and boost, while the mobile part has a 300 MHz base clock and a 1750 MHz boost clock. The discrete card's higher shading unit count combined with its higher sustained clock speed explains its compute advantage. The Arc A310E supports DirectX 12 Ultimate (12_2), while the mobile part supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The discrete card is PCIe 4.0 x8, while the mobile IGP connects via Ring Bus. The Arc A310E is a single-slot card measuring 168 mm in length, 69 mm in height, and 20 mm in width, with four mini-DisplayPort 2.0 outputs. The mobile part has no fixed dimensions and its display outputs are portable device dependent. The discrete card has a 75 W TDP and requires no power connectors, with a suggested power supply of 250 W. The mobile part has a 65 W TDP. The Arc A310E is marked as end-of-life production status with a release date of 2024-03-31, while the mobile part remains active with a release date of 2023-12-13. The Arc A310E lists Xe Graphics as its predecessor and Battlemage as its successor, while the mobile part lists HD Graphics-M as its predecessor and no successor.

Head-to-Head Benchmarks

The database records no direct benchmark scores for either GPU, but the specification-derived performance metrics provide a clear quantitative comparison. The Arc A310E achieves 3.072 TFLOPS FP32 performance, which is 1.71 times the 1.792 TFLOPS of the Arc Graphics 64EU Mobile. In FP16, the discrete card reaches 6.144 TFLOPS, compared to 3.584 TFLOPS for the mobile part, again a 1.71x advantage. Pixel fill rate favors the discrete card at 32.00 GPixel/s versus 28.00 GPixel/s for the integrated solution, a 14% difference. Texture fill rate shows a similar pattern: 64.00 GTexel/s for the Arc A310E versus 56.00 GTexel/s for the mobile part, a 14% advantage. Memory bandwidth presents the most dramatic gap. The Arc A310E has 4 GB of GDDR6 memory on a 64-bit bus, delivering 124.0 GB/s of bandwidth. The mobile part uses system shared memory with system dependent bandwidth, which the database lists as "System Dependent." The discrete card's memory clock runs at 1937 MHz with 15.5 Gbps effective speed. The Arc A310E also has 6 ray tracing cores, a feature entirely absent from the mobile part's specification list. Both GPUs share the same texture mapping unit count of 32 and raster output unit count of 16, meaning the pixel and texture rate differences stem from clock speed rather than unit count. The Arc A310E's pixel rate advantage of 4 GPixel/s and texture rate advantage of 8 GTexel/s both trace to its 2000 MHz clock versus the mobile part's 1750 MHz boost clock, combined with the discrete card's higher shading unit count. The fixed 2000 MHz base and boost clock on the Arc A310E means no clock fluctuation under load, while the mobile part's 300 MHz base clock rising to 1750 MHz suggests significant dynamic clock scaling behavior in the integrated environment.

Where Each One Wins

The Intel Arc A310E wins decisively in compute-intensive scenarios. Its 3.072 TFLOPS FP32 throughput, 6.144 TFLOPS FP16 throughput, and 6 ray tracing cores position it for workloads that leverage these capabilities. The dedicated 124.0 GB/s GDDR6 memory bandwidth eliminates contention with the host system, and the PCIe 4.0 x8 interface provides a direct connection to the platform. The four mini-DisplayPort 2.0 outputs support multi-display configurations. The fixed 2000 MHz clock ensures consistent performance without thermal or power-driven clock variation. The card's single-slot, 168 mm length, and absence of power connectors allow installation in compact systems with a 250 W power supply. Its DirectX 12 Ultimate support enables the latest graphics API features. The Arc Graphics 64EU Mobile wins in integration scenarios. Its 65 W TDP fits within the power envelope of portable devices, and its Ring Bus connection to the Meteor Lake chip eliminates the need for separate graphics memory. The system shared memory approach allows flexible allocation of memory resources based on workload demands. As an active production part, it remains available for current mobile designs. Its 512 shading units and 1750 MHz boost clock provide moderate graphics capability without discrete hardware. The 28.00 GPixel/s pixel rate and 56.00 GTexel/s texture rate handle standard display and composition tasks. The Arc A310E holds the advantage in raw graphics throughput, memory bandwidth, ray tracing, and API feature support. The mobile part holds the advantage in physical integration, power efficiency within its class, and availability for new portable products. The Arc A310E's end-of-life status means design wins for that card are closed, while the mobile part continues in production. Both GPUs share the same texture mapping unit count and raster output unit count, so texture-heavy workloads scale with clock speed and shading unit availability. The Arc A310E's higher shading unit count (768 versus 512) and higher clock (2000 MHz versus 1750 MHz boost) combine to produce the measured throughput advantages. The mobile part's lower base clock of 300 MHz suggests it spends significant time at reduced power states, with boost to 1750 MHz available when needed. The Arc A310E's 32.00 GPixel/s pixel rate suits high-resolution display output, while the mobile part's 28.00 GPixel/s handles typical integrated graphics duties. The database records both GPUs at the 50th percentile against all GPUs, indicating average positioning within the full graphics landscape. The Arc A310E's 6 ray tracing cores provide hardware acceleration for ray-traced effects, a capability absent from the mobile part. The discrete card's 157 mm² die built on TSMC's 6 nm process with 7,200 million transistors delivers higher density than the mobile part's unspecified Intel 10 nm design. The Arc A310E's memory clock of 1937 MHz with 15.5 Gbps effective speed represents the dedicated memory subsystem's performance capability. The Arc Graphics 64EU Mobile's predecessor is HD Graphics-M, while the Arc A310E's predecessor is Xe Graphics, showing both parts continue Intel's integrated and discrete graphics lineages respectively.
