Intel Arc A770 vs NVIDIA RTX A1000 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive picture: the Intel Arc A770 wins both recorded head-to-head comparisons, and it does so by a substantial margin. In the Geekbench OpenCL test, the Arc A770 scores 109,175 against the RTX A1000 Mobile’s 48,703, a 124.2% advantage. That is more than double the raw compute output in a general-purpose GPU workload. In Geekbench Vulkan, the gap narrows slightly but remains overwhelming: 94,284 versus 46,782, a 101.5% delta. The Arc A770 effectively doubles the NVIDIA part’s performance in both API environments.

These are not close contests. The smallest winning margin across the two tests is 101.5%, which means the Intel GPU delivers at least twice the performance in every measured scenario. The RTX A1000 Mobile never wins a single head-to-head benchmark, and its best result, 48,703 in OpenCL, is still less than half of the Arc A770’s lowest score in either test. The data shows a product class gap rather than a generational refinement.

Context from the broader database reinforces this split. The Arc A770 sits at the 90th percentile among all GPUs, with an average benchmark score of 68,809. Its nearest rivals in the database, the NVIDIA CMP 90HX at 69,000 and the AMD Radeon Instinct MI25 at 68,562, are within 0.3% to 0.4% of that average. The RTX A1000 Mobile, by contrast, lands at the 85th percentile with an average score of 47,743. Its closest competitors, the AMD Radeon RX 6800 XT at 48,477 and the AMD Radeon RX 6550M at 46,702, sit within 1.5% to 2.2% of its average. The percentile difference, 90 versus 85, understates the raw score gap: the Arc A770’s average is 44% higher than the RTX A1000 Mobile’s average.

The delta percentages in the head-to-head results are the clearest signal. A 124.2% lead in OpenCL means the Intel part does more than twice the work per unit time. A 101.5% lead in Vulkan means the same in a graphics-heavy context. No amount of driver tuning or workload selection closes a gap that large. The RTX A1000 Mobile is competitive with lower-tier desktop and mobile parts, but it is not in the Arc A770’s performance class.

Architecture Differences

The two GPUs come from fundamentally different design philosophies and manufacturing approaches. The Intel Arc A770 uses the DG2-512 chip built on the Xe-HPG architecture, part of the Alchemist generation for Arc 7. It is fabricated on a 6 nm process at TSMC, packing 21,700 million transistors into a 406 mm² die. The transistor density works out to 53.4 million per square millimeter. The NVIDIA RTX A1000 Mobile uses the GA107 chip on the Ampere architecture, part of the Ampere-MW generation for the Ax000 series. It is built on an 8 nm process at Samsung, with 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per square millimeter.

The process node difference, 6 nm versus 8 nm, explains part of the transistor density gap, but the gross transistor count difference is the dominant factor. Intel’s chip has 2.5 times the transistor budget of NVIDIA’s, and it deploys that budget across a much larger die. The Intel part also differs in its ray tracing implementation: it has 32 ray tracing cores, while the NVIDIA part has 16. The NVIDIA part counters with 64 tensor cores, a feature the Arc A770 does not list at all.

API support is identical on paper. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The underlying hardware, however, diverges sharply. The Arc A770’s Xe-HPG architecture is designed for high throughput across a wide memory bus, while the RTX A1000 Mobile’s Ampere architecture is a mobile-first design with a much narrower footprint. The Intel part is a dual-slot desktop card with power connectors; the NVIDIA part is an integrated GPU package (IGP) with no power connectors, designed for portable devices. The bus interface also differs: the Arc A770 uses PCIe 4.0 x16, while the RTX A1000 Mobile uses PCIe 4.0 x8. That halved lane count further constrains the mobile part’s bandwidth to the host system.

The foundry choice also signals intent. Intel went to TSMC for a leading-edge 6 nm process, while NVIDIA used Samsung’s 8 nm node. The result is a transistor density advantage of roughly 23% for Intel, but the real story is the raw scale: the Arc A770 has more than twice the shader units, four times the texture mapping units, and four times the render output units. These architectural differences cascade directly into the benchmark results.

Specification Differences

The specification sheet shows a wide gap across nearly every measurable field. The Arc A770 has 4,096 shading units, 256 TMUs, and 128 ROPs. The RTX A1000 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs. That is exactly double the shaders, quadruple the TMUs, and quadruple the ROPs for Intel. The ray tracing core count also doubles: 32 versus 16. The NVIDIA part has 64 tensor cores, which the Intel part does not list.

Clock speeds differ substantially. The Arc A770 runs at a base clock of 2100 MHz and boosts to 2400 MHz. The RTX A1000 Mobile runs at 630 MHz base and 1140 MHz boost. Intel’s base clock is more than three times NVIDIA’s base clock, and its boost clock is more than double. Memory clocks follow a similar pattern: the Arc A770 uses 2000 MHz (16 Gbps effective), while the RTX A1000 Mobile runs at 1375 MHz (11 Gbps effective).

Memory capacity and bandwidth favor Intel overwhelmingly. The Arc A770 has 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, yielding 176.0 GB/s. That is four times the capacity and roughly three times the bandwidth. The pixel rate tells the same story: 307.2 GPixel/s for Intel versus 36.48 GPixel/s for NVIDIA. Texture rate is 614.4 GTexel/s versus 72.96 GTexel/s.

Compute throughput is equally lopsided. The Arc A770 delivers 19.66 TFLOPS of FP32 and 39.32 TFLOPS of FP16 (2:1 ratio). The RTX A1000 Mobile delivers 4.669 TFLOPS of FP32 and 4.669 TFLOPS of FP16 (1:1 ratio). The Intel part is 4.2 times faster in FP32 and 8.4 times faster in FP16. Power draw reflects the performance gap: the Arc A770 is rated at 225 W TDP, while the RTX A1000 Mobile is rated at 60 W. The Intel card requires a 550 W suggested PSU and dual power connectors, while the NVIDIA mobile part has no connectors and no suggested PSU. Display outputs also differ: the Arc A770 offers 1x HDMI 2.1 and 3x DisplayPort 2.0, while the RTX A1000 Mobile is listed as portable device dependent.

Where Each One Wins

The Arc A770 wins every recorded benchmark, so the use-case split is defined by magnitude rather than direction. In Geekbench OpenCL, a compute-heavy workload, the Intel part leads by 124.2%. That makes it the clear choice for any general-purpose GPU compute task, from rendering to data processing. In Geekbench Vulkan, a graphics-focused API, the lead is 101.5%. The Arc A770 is also the only one of the two with a 3DMark Steel Nomad DX12 result in the database, scoring 2,969, which gives it an additional documented win in a modern DirectX 12 workload.

The RTX A1000 Mobile does have one architectural advantage: tensor cores. With 64 tensor cores, it can accelerate AI and machine learning workloads that the Arc A770 lacks dedicated hardware for. However, the benchmark data does not include any tensor-specific tests, so the practical impact cannot be quantified from the recorded scores. The RTX A1000 Mobile also draws far less power, 60 W versus 225 W, making it suitable for thin-and-light portable devices. Its IGP form factor and lack of power connectors mean it can fit into chassis that cannot accommodate a dual-slot card.

For raw performance, the Arc A770 wins in the two tested APIs and adds a third win in 3DMark Steel Nomad. The RTX A1000 Mobile wins in power efficiency and portability, but those are form-factor wins, not performance wins. The recorded data shows no benchmark where the NVIDIA part comes out ahead. The Arc A770’s 90th percentile rank versus the RTX A1000 Mobile’s 85th percentile rank underscores the same conclusion: in the database’s measurements, the Intel part occupies a higher performance tier entirely.

The Verdict

The data is unambiguous. The Intel Arc A770 wins both head-to-head benchmarks, with deltas of 124.2% in OpenCL and 101.5% in Vulkan. Its average benchmark score of 68,809 places it at the 90th percentile, while the RTX A1000 Mobile’s average of 47,743 places it at the 85th. The Arc A770 also holds a 3DMark Steel Nomad DX12 score of 2,969, a test the NVIDIA part does not have recorded. Anyone choosing between these two for performance should select the Arc A770 without hesitation.

The RTX A1000 Mobile is not without a role. Its 60 W TDP, IGP form factor, and lack of power connectors make it a viable option for portable devices where power draw and physical space are the primary constraints. Its 64 tensor cores also provide dedicated AI acceleration hardware that the Arc A770 lacks. But the benchmark results show that in raw compute and graphics performance, the Arc A770 is in a different league. The recorded data shows the NVIDIA part losing by at least 101.5% in every shared test.

The Arc A770’s launch MSRP was 329 USD, but the more relevant facts are its 16 GB memory capacity, 512.0 GB/s bandwidth, and 19.66 TFLOPS of FP32 compute. The RTX A1000 Mobile offers 4 GB memory, 176.0 GB/s bandwidth, and 4.669 TFLOPS. For workloads that fit within the Intel card’s power budget, the choice is clear. For constrained mobile environments, the RTX A1000 Mobile remains a functional option, but it cannot match the Arc A770’s performance tier. The verdict from the database: the Arc A770 is the faster GPU, and the RTX A1000 Mobile is the more portable one. These are different products for different physical contexts, but on pure performance, Intel wins every recorded contest.
