Intel Arc A750 vs NVIDIA GeForce RTX 3070 Comparison

Head-to-Head Benchmarks

The benchmark data presents a striking split between these two cards. The Intel Arc A750 claims a single victory, but it is an emphatic one. In Geekbench Vulkan, the Arc A750 scores 85,631 against the RTX 3070's 21,022, a delta of 307.3% in Intel's favor. This is not a marginal lead; it is a dominant result that suggests a fundamental advantage in Vulkan workload execution.

Every other recorded test favors the NVIDIA GeForce RTX 3070. In 3DMark Steel Nomad DX12, the RTX 3070 posts 3,162 versus 2,612 for the Arc A750, a 17.4% gap. The OpenCL test shows a similar pattern: NVIDIA leads 112,821 to 98,554, a 12.6% difference. PassMark results widen the margin considerably. In DirectX 11, the RTX 3070 scores 182 against the Arc A750's 72, a 60.4% deficit for Intel. DirectX 10 shows the RTX 3070 at 150 versus 65, a 56.7% gap. Even in older DirectX 9, NVIDIA leads 247 to 181, a 26.7% advantage.

The largest PassMark deltas appear in compute and general 3D workloads. PassMark G3D shows the RTX 3070 at 22,214 versus 12,534, a 43.6% lead. PassMark GPU Compute favors NVIDIA even more decisively: 11,195 versus 5,368, a 52.1% deficit for the Arc A750. DirectX 12 results are comparatively close, with the RTX 3070 winning 85 to 70, a 17.6% margin. PassMark G2D also goes to NVIDIA, 1,001 versus 732, a 26.9% gap.

The average benchmark score reinforces the overall picture. The RTX 3070 averages 17,208, while the Arc A750 averages 20,582. This is an unusual situation: the Intel card has a higher average score yet loses nine of ten head-to-head tests. The explanation lies in that Vulkan outlier, which inflates the Arc's average. The RTX 3070 sits in the 61st percentile of all GPUs, while the Arc A750 ranks in the 66th percentile, again driven by its Vulkan performance. The data suggests the Arc A750 is a specialized performer, while the RTX 3070 delivers consistent results across a broader range of APIs.

Architecture Differences

The two cards come from fundamentally different design philosophies. Intel's Arc A750 uses the DG2-512 chip built on Xe-HPG architecture, manufactured on a 6 nm process at TSMC. The RTX 3070 uses the GA104 chip with Ampere architecture, fabricated on Samsung's 8 nm node. The process difference is significant: Intel packs 21,700 million transistors into a 406 mm² die, yielding a density of 53.4 million transistors per square millimeter. NVIDIA crams 17,400 million transistors into 392 mm², a density of 44.4 million per square millimeter. Intel's smaller process node gives it a clear transistor density advantage.

The compute resources tell a different story. The RTX 3070 has 5,888 shading units, 184 texture mapping units, and 96 ROPs. The Arc A750 counters with 3,584 shading units, 224 TMUs, and 112 ROPs. NVIDIA has far more shading units, but Intel has more TMUs and ROPs. This explains some of the texture and pixel rate differences. The Arc A750 delivers 537.6 GTexel/s and 268.8 GPixel/s, while the RTX 3070 manages 317.4 GTexel/s and 165.6 GPixel/s. Intel's advantage in raw texture and pixel throughput does not translate into benchmark wins, which indicates that driver efficiency and workload characteristics matter more than peak theoretical rates.

Ray tracing hardware differs substantially. The RTX 3070 has 46 RT cores and 184 tensor cores. The Arc A750 has 28 RT cores and no tensor core equivalent listed in the database. NVIDIA's tensor cores support DLSS and other AI-accelerated features, giving it a feature set the Arc cannot match. The FP32 output also favors NVIDIA: 20.31 TFLOPS versus 17.20 TFLOPS for Intel. The FP16 comparison is intriguing. The Arc A750 produces 34.41 TFLOPS at a 2:1 ratio, while the RTX 3070 produces 20.31 TFLOPS at a 1:1 ratio. Intel's FP16 throughput is higher, but the RTX 3070's 1:1 ratio suggests it treats FP16 and FP32 equally, which can be advantageous in certain compute workloads.

Clock speeds diverge sharply. The Arc A750 runs at a 2050 MHz base clock and boosts to 2400 MHz. The RTX 3070 operates at 1500 MHz base and 1725 MHz boost. Intel's higher clocks partly offset its lower shading unit count, but the benchmark results show that raw clock speed does not overcome NVIDIA's architectural efficiency. Memory configuration is similar in capacity and bus width: both have 8 GB GDDR6 on a 256-bit bus. However, the Arc A750 runs its memory at 2000 MHz with 16 Gbps effective speed, yielding 512.0 GB/s of bandwidth. The RTX 3070's memory runs at 1750 MHz with 14 Gbps effective, giving 448.0 GB/s. Intel holds a 14.3% memory bandwidth advantage, yet again this does not produce wins in the recorded benchmarks.

Where Each One Wins

The data points to a clear specialization for the Intel Arc A750: Vulkan compute and rendering. Its 307.3% lead in Geekbench Vulkan is the single largest margin in the entire comparison. This suggests that applications built on Vulkan, particularly those leveraging modern graphics features, could see exceptional performance on the Arc A750. The card's higher texture rate, pixel rate, and memory bandwidth align with this strength. Workloads that stress these subsystems, such as certain Vulkan-based games or compute tasks, may favor Intel.

The NVIDIA GeForce RTX 3070 wins across essentially every other scenario. Its 60.4% lead in DirectX 11 shows strength in legacy API workloads, which remain common in many games. The 56.7% advantage in DirectX 10 reinforces this pattern. DirectX 12 shows a narrower 17.6% lead, indicating that Intel's newer architecture performs better in modern APIs but still falls short. The compute results are particularly lopsided: a 52.1% gap in PassMark GPU Compute and a 12.6% gap in OpenCL. For productivity tasks, content creation, or any GPU compute workload, the RTX 3070 is the clear choice based on these numbers.

The RTX 3070 also dominates in general 3D rendering, with a 43.6% lead in PassMark G3D. This is the broadest measure of gaming performance in the dataset, and it strongly favors NVIDIA. The 26.9% lead in G2D shows even 2D tasks run faster on the RTX 3070. Users seeking a versatile card that handles all workloads competently should look to NVIDIA. Users with specific Vulkan-centric workloads might find the Arc A750 unexpectedly competitive, but the data warns that this strength does not extend to other APIs.

Specification Differences

The two cards differ on several key specifications. The Intel Arc A750 uses a 6 nm process from TSMC, while the RTX 3070 uses Samsung's 8 nm node. Intel's die is 406 mm² with 21,700 million transistors; NVIDIA's is 392 mm² with 17,400 million. Transistor density favors Intel at 53.4M per mm² versus 44.4M per mm².

Clock speeds favor Intel substantially: 2050 MHz base and 2400 MHz boost versus 1500 MHz and 1725 MHz for the RTX 3070. Memory bandwidth also favors Intel at 512.0 GB/s versus 448.0 GB/s, though both use 8 GB GDDR6 on a 256-bit bus. The memory clock differs, with Intel at 2000 MHz and 16 Gbps effective, NVIDIA at 1750 MHz and 14 Gbps effective.

Shader resources favor NVIDIA: 5,888 shading units versus 3,584. Intel counters with more TMUs (224 versus 184) and ROPs (112 versus 96). Ray tracing hardware favors NVIDIA with 46 RT cores versus 28, and NVIDIA adds 184 tensor cores that Intel lacks entirely. FP32 output favors NVIDIA at 20.31 TFLOPS versus 17.20 TFLOPS. FP16 output favors Intel at 34.41 TFLOPS versus 20.31 TFLOPS, with different ratios (2:1 for Intel, 1:1 for NVIDIA).

Power draw is similar: 225 W for Intel, 220 W for NVIDIA, both with a suggested 550 W PSU. Both are dual-slot cards with PCIe 4.0 x16 interfaces. Display outputs differ: Intel offers 1x HDMI 2.1 and 3x DisplayPort 2.0, while NVIDIA offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. Power connectors differ: Intel uses 1x 6-pin plus 1x 8-pin, NVIDIA uses a single 12-pin. The RTX 3070 has recorded dimensions of 242 mm length and 112 mm height; the Arc A750's dimensions are not listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The launch MSRP for the Arc A750 is 289 USD, and for the RTX 3070 it is 499 USD.

The Verdict

The recorded data draws a clear line between these two GPUs. The NVIDIA GeForce RTX 3070 is the more consistent performer, winning nine of ten head-to-head benchmarks with margins ranging from 12.6% to 60.4%. It leads in every API except Vulkan, including the DirectX 11, DirectX 12, and OpenCL tests that represent the majority of gaming and compute workloads. Its 5,888 shading units and 46 RT cores provide a solid foundation for these results, and the 184 tensor cores add AI capabilities the Arc A750 cannot match.

The Intel Arc A750 is a paradox. Its Vulkan score is extraordinary, more than four times the RTX 3070's result in that specific test. Its higher clock speeds, greater memory bandwidth, and larger transistor density show that the hardware is capable. Yet the data shows this potential rarely translates into wins outside Vulkan. The 17.6% DirectX 12 deficit is respectable, but the 60.4% DirectX 11 gap and 52.1% compute gap are decisive.

Users who prioritize broad compatibility and consistent performance should choose the RTX 3070. It is the safer pick for mixed workloads, legacy API support, and compute-heavy tasks. Users whose software relies heavily on Vulkan may find the Arc A750 compelling, particularly given its higher average score and strong theoretical specifications. However, the data suggests this is a narrow use case. For almost every measured scenario, the RTX 3070 delivers superior results.
