Intel Arc A770 vs NVIDIA RTX A3000 Mobile Comparison

The benchmark data places the Intel Arc A770 decisively ahead of the NVIDIA RTX A3000 Mobile in the tests recorded, with the Arc A770 winning both head-to-head comparisons. Despite the RTX A3000 Mobile holding a slightly higher average benchmark score across all GPUs (70140 vs 68809), the direct comparisons show a clear performance gap favoring the Intel part, particularly in Vulkan workloads.

Head-to-Head Benchmarks

The Intel Arc A770 dominates the shared benchmark suite, winning both recorded tests. In Geekbench OpenCL, the Arc A770 scores 109175 against the RTX A3000 Mobile’s 79091, a 27.6% advantage. This is a substantial margin that indicates significantly higher raw compute throughput in OpenCL-based applications, which often scale with shader count and memory bandwidth.

The gap widens further in Geekbench Vulkan, where the Arc A770 achieves 94284 versus 61189 for the RTX A3000 Mobile. The 35.1% delta here is the largest single-test difference between the two, suggesting that the Intel architecture extracts comparatively more performance from Vulkan’s lower-level API overhead. This result is notable because Vulkan performance often reflects driver efficiency and hardware scheduling capabilities rather than just raw specs.

Context from the nearestRivals data reinforces the separation. The RTX A3000 Mobile’s average score of 70140 places it 1.9% above the Arc A770’s 68809 average, but that overall figure is buoyed by other benchmarks not shared between them. In the tests where both GPUs appear, the Arc A770 is consistently faster. The deltaPct values in the head-to-head table are negative for the RTX A3000 Mobile in both cases, confirming that the NVIDIA part trails in every direct comparison available.

It is also notably the RTX A3000 Mobile’s nearestRivals list includes the Arc A770 with a deltaPct of 1.9%, meaning the NVIDIA GPU’s average score is just under 2% higher. However, that aggregate statistic masks the per-test reality shown in the head-to-head section, where the Arc A770 leads by margins of 27.6% and 35.1%. The discrepancy arises because the two GPUs have different benchmark portfolios, and the RTX A3000 Mobile’s average is propped up by tests the Arc A770 did not run.

The Verdict

The data points to a clear winner for compute-heavy workloads: the Intel Arc A770. It wins both shared benchmarks with margins of 27.6% (OpenCL) and 35.1% (Vulkan). If the decision rests solely on the recorded Geekbench results, the Arc A770 is the superior choice for applications that leverage these APIs.

However, the RTX A3000 Mobile is not without merit. Its higher average benchmark score (70140 vs 68809) and its position in the 92nd percentile of all GPUs indicate that it performs strongly in a broader test suite. The RTX A3000 Mobile also holds a 1.9% advantage over the Arc A770 in average score, per the nearestRivals data. Buyers who prioritize consistency across a wide range of benchmarks might favor the NVIDIA part, even though it loses the direct comparisons.

The Arc A770’s launch MSRP is 329 USD, while the RTX A3000 Mobile has no recorded launch MSRP in the data. That difference, combined with the Arc A770’s benchmark wins, makes the Intel GPU the more compelling choice for those who value raw performance in OpenCL and Vulkan workloads. The RTX A3000 Mobile, being an end-of-life mobile part, may appeal to users who need its specific form factor or who rely on the NVIDIA ecosystem for other reasons not captured in these benchmarks.

Where Each One Wins

The Intel Arc A770 wins in every shared benchmark category. Its OpenCL score of 109175 is 27.6% higher than the RTX A3000 Mobile’s 79091, making it the clear pick for OpenCL compute tasks such as scientific simulations, video encoding, or machine learning inference that rely on this API. The Vulkan result is even more lopsided: 94284 vs 61189, a 35.1% lead that suggests the Arc A770 is particularly well-suited for Vulkan-based game engines or graphics applications that exploit explicit multi-threading.

The RTX A3000 Mobile’s wins are less visible in the head-to-head data, but its average benchmark score of 70140 exceeds the Arc A770’s 68809 by 1.9%. This implies that in tests not shared between the two, the NVIDIA GPU performs relatively better. For users who run a mix of benchmarks or applications that are not primarily OpenCL or Vulkan, the RTX A3000 Mobile may deliver more consistent results overall. Its 92nd percentile ranking matches the Arc A770’s, indicating both are top-tier performers.

The RTX A3000 Mobile also wins on power efficiency, with a 70 W TDP compared to the Arc A770’s 225 W. This is a massive difference that makes the mobile NVIDIA part suitable for laptops or compact systems where thermal and power constraints are paramount. The Arc A770, by contrast, requires a 550 W suggested PSU and dual-slot cooling, making it a desktop-only proposition.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The NVIDIA RTX A3000 Mobile uses the GA104 chip built on Ampere architecture, manufactured by Samsung on an 8 nm process. It integrates 17,400 million transistors on a 392 mm² die, yielding a transistor density of 44.4M per mm². The Intel Arc A770, in contrast, uses the DG2-512 chip based on Xe-HPG architecture, fabricated by TSMC on a 6 nm process. It packs 21,700 million transistors on a 406 mm² die, achieving 53.4M transistors per mm².

Shading units are identical at 4096 for both, but the similarity ends there. The Arc A770 has 256 TMUs and 128 ROPs, double the RTX A3000 Mobile’s 128 TMUs and 64 ROPs. Both feature 32 ray tracing cores, but the RTX A3000 Mobile also includes 128 tensor cores, which the Arc A770 lacks entirely. This tensor core presence gives the NVIDIA part a hardware advantage for AI workloads that leverage tensor operations, though the recorded benchmarks do not test this capability.

Clock speeds differ dramatically. The RTX A3000 Mobile runs at a 600 MHz base and 1230 MHz boost, while the Arc A770 operates at 2100 MHz base and 2400 MHz boost. This nearly 2x clock advantage explains much of the Arc A770’s higher fill rates: its pixel rate is 307.2 GPixel/s versus 78.72 GPixel/s for the NVIDIA part, and its texture rate is 614.4 GTexel/s versus 157.4 GTexel/s.

Memory architecture also diverges. The RTX A3000 Mobile uses 6 GB of GDDR6 with a 192-bit bus and 264.0 GB/s bandwidth. The Arc A770 has 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth. The effective memory speed is 11 Gbps for the NVIDIA GPU and 16 Gbps for the Intel GPU, compounding the bandwidth advantage.

Specification Differences

The most obvious specification difference is memory capacity: 6 GB on the RTX A3000 Mobile versus 16 GB on the Arc A770. This 10 GB gap is significant for large datasets or high-resolution textures. Memory bus width follows suit, with 192-bit on the NVIDIA part and 256-bit on the Intel part.

Compute throughput diverges sharply. The RTX A3000 Mobile delivers 10.08 TFLOPS of FP32 performance, while the Arc A770 doubles that to 19.66 TFLOPS. For FP16, the RTX A3000 Mobile maintains a 1:1 ratio at 10.08 TFLOPS, whereas the Arc A770 achieves 39.32 TFLOPS with a 2:1 ratio, indicating twice the throughput for half-precision workloads.

Power consumption is a major differentiator. The RTX A3000 Mobile has a 70 W TDP and requires no power connectors, making it suitable for mobile deployments. The Arc A770 has a 225 W TDP, needs a dual-slot cooler, and draws power from one 6-pin and one 8-pin connector. The suggested PSU for the Intel card is 550 W, while the NVIDIA part has no such recommendation.

Display outputs also differ: the RTX A3000 Mobile features portable device dependent outputs, while the Arc A770 offers 1x HDMI 2.1 and 3x DisplayPort 2.0. The bus interface is PCIe 4.0 x16 for both. Release dates are about 18 months apart, with the RTX A3000 Mobile launching in April 2021 and the Arc A770 in October 2022. Both are end-of-life products, with the NVIDIA part succeeding Ada-MW and the Intel part succeeding Battlemage.
