Intel Arc A770 vs NVIDIA GeForce RTX 4080 SUPER Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity about the performance hierarchy between these two GPUs. Across every shared benchmark in the database, the NVIDIA GeForce RTX 4080 SUPER delivers a commanding victory. The most decisive margin appears in the Geekbench Vulkan test, where the RTX 4080 SUPER scores 260075 against the Arc A770's 94284, a delta of 63.7% in NVIDIA's favor. This is not a marginal gap; it is a generational chasm in raw compute throughput under the Vulkan API.

The 3DMark Steel Nomad DX12 test tells a similar story, though with a slightly narrower spread. The RTX 4080 SUPER posts 6600 points while the Arc A770 manages 2969, resulting in a 55% deficit for the Intel part. This benchmark stresses modern DirectX 12 workloads with ray tracing and mesh shading, and the results indicate that the NVIDIA architecture handles these tasks with substantially more headroom.

Geekbench OpenCL shows the RTX 4080 SUPER at 219065 versus 109175 for the Arc A770, a 50.2% advantage. Interestingly, this is the closest of the three comparisons, yet it still represents a doubling of raw OpenCL performance. The pattern across all three tests is consistent: the RTX 4080 SUPER leads by roughly half to nearly two-thirds, and the Arc A770 never claims a single head-to-head victory in the database. The wins tally stands at zero for Intel and three for NVIDIA.

What is striking is how the margins vary by API. Vulkan shows the largest gap at 63.7%, while OpenCL shows the smallest at 50.2%. This suggests the NVIDIA GPU scales its advantage differently depending on the workload type, with compute-heavy Vulkan tasks exposing the widest performance differential. The DX12 result sits between the two, indicating that the gap narrows somewhat under graphics-centric loads but remains overwhelming nonetheless.

Architecture Differences

The underlying silicon tells a fascinating story of two very different design philosophies. The Intel Arc A770 uses the DG2-512 chip built on TSMC's 6 nm process, packing 21,700 million transistors into a 406 mm² die. This yields a transistor density of 53.4 million per square millimeter. In contrast, the NVIDIA GeForce RTX 4080 SUPER uses the AD103 chip on TSMC's 5 nm node, with 45,900 million transistors squeezed into a smaller 379 mm² die, achieving a density of 121.1 million per square millimeter. That is more than double the density per area, a direct consequence of the more advanced fabrication node.

The architectural lineage also diverges sharply. Intel's Xe-HPG architecture, codenamed Alchemist and belonging to the Arc 7 generation, represents Intel's first serious foray into discrete gaming GPUs. NVIDIA's Ada Lovelace architecture, meanwhile, is the third generation of the GeForce 40-series, building on the predecessor GeForce 30 line. This generational maturity shows in the feature set and execution.

Memory subsystems differ in type and speed even though capacity and bus width match. Both cards carry 16 GB of VRAM on a 256-bit bus, but the Arc A770 uses GDDR6 at 16 Gbps effective, yielding 512.0 GB/s of bandwidth. The RTX 4080 SUPER steps up to GDDR6X at 23 Gbps effective, producing 736.3 GB/s, a 43.8% bandwidth advantage. This directly impacts texture-heavy workloads and high-resolution rendering where memory throughput becomes the bottleneck.

Compute resources also differ dramatically. The Arc A770 fields 4096 shading units, 256 TMUs, and 128 ROPs, alongside 32 ray tracing cores. The RTX 4080 SUPER counters with 10240 shading units, 320 TMUs, and 112 ROPs, plus 80 ray tracing cores and 320 tensor cores. NVIDIA's advantage in shading units is 150%, and its ray tracing core count is 2.5 times higher. Interestingly, the Arc A770 has more ROPs (128 versus 112), yet its pixel rate of 307.2 GPixel/s edges out the RTX 4080 SUPER's 285.6 GPixel/s. This is one of the few raw specification categories where Intel leads.

Clock behavior also differs. The Arc A770 runs at a 2100 MHz base and 2400 MHz boost, while the RTX 4080 SUPER operates at 2295 MHz base and 2550 MHz boost. The NVIDIA card's higher clocks, combined with its massive shading unit advantage, produce a FP32 throughput of 52.22 TFLOPS versus 19.66 TFLOPS for Intel. That is a 165.6% difference in raw floating-point performance. FP16 tells an even more divergent story: the Arc A770 achieves 39.32 TFLOPS via a 2:1 ratio, while the RTX 4080 SUPER delivers 52.22 TFLOPS at a 1:1 ratio, meaning NVIDIA maintains full rate without the halving penalty.

Power delivery and physical design reflect the performance gap. The Arc A770 draws 225 W TDP with a suggested 550 W PSU, using a 1x 6-pin plus 1x 8-pin connector arrangement and a dual-slot cooler. The RTX 4080 SUPER consumes 320 W, requires a 700 W PSU, uses a single 16-pin connector, and occupies a triple-slot design measuring 310 mm in length. The NVIDIA card is physically larger and hungrier, but the data shows that power budget is converted directly into performance.

Where Each One Wins

Given the benchmark sweep, the use-case split is lopsided but not entirely devoid of nuance. The RTX 4080 SUPER wins every recorded benchmark, so any workload represented by 3DMark Steel Nomad DX12, Geekbench OpenCL, or Geekbench Vulkan belongs to NVIDIA. For gamers targeting high-framerate 1440p or 4K DX12 titles, the 55% lead in Steel Nomad indicates a substantial experience gap. For compute-oriented users leveraging OpenCL, the 50.2% advantage means rendering, simulation, and GPGPU tasks will complete in roughly two-thirds of the time.

The Vulkan result is particularly telling for modern game engines and cross-platform titles. A 63.7% lead in Geekbench Vulkan suggests the RTX 4080 SUPER handles Vulkan's lower-level API overhead with far greater efficiency, which translates to better frame pacing and higher average framerates in Vulkan-based games.

For the Arc A770, the wins are more subtle and reside outside the benchmark suite. Its 16 GB of GDDR6 memory matches the RTX 4080 SUPER's capacity, which is notable for a card in its class. The higher ROP count and pixel rate (307.2 GPixel/s versus 285.6 GPixel/s) suggest that fill-rate-bound scenarios, such as certain legacy or simple geometry workloads, could see the Intel card perform competitively, though the database does not include a benchmark that isolates this. The lower 225 W TDP also implies less system-level stress, and the dual-slot form factor fits in more compact cases than the RTX 4080 SUPER's triple-slot girth. The DisplayPort 2.0 output on the Arc A770, versus DisplayPort 1.4a on the NVIDIA card, gives Intel an edge in display connectivity for future high-refresh monitors, though no benchmark in the database measures this.

The Verdict

The data paints a clear picture: the NVIDIA GeForce RTX 4080 SUPER is in a different performance class entirely. With wins across every shared benchmark and margins ranging from 50.2% to 63.7%, there is no scenario in the recorded measurements where the Intel Arc A770 competes on equal footing. The RTX 4080 SUPER's 52.22 TFLOPS of FP32 compute, 736.3 GB/s of memory bandwidth, and 80 ray tracing cores combine to produce results that the Arc A770 cannot approach.

The Arc A770's strengths are narrower and more specification-driven than benchmark-driven. Its 16 GB memory capacity matches the RTX 4080 SUPER, its pixel rate is actually higher, and its 225 W TDP with dual-slot cooling makes it a more manageable card for constrained builds. It also carries DisplayPort 2.0 outputs, which the NVIDIA card lacks. For users whose workloads align with these specific advantages, the Arc A770 remains a viable option, but the database shows no performance category where it leads.

The percentile data reinforces this hierarchy. The Arc A770 sits at the 90th percentile among all GPUs, while the RTX 4080 SUPER sits at the 86th percentile. Despite the lower percentile, the RTX 4080 SUPER's average benchmark score of 54209 exceeds the Arc A770's 68809 in the database's scoring system, which weights different test suites. The nearest rivals for each card tell the story: the Arc A770 competes with the NVIDIA CMP 90HX (0.3% behind) and AMD Radeon Pro WX 8200 (1.5% ahead), while the RTX 4080 SUPER trades blows with the RTX 4080 (0.1% behind) and AMD Radeon RX 6750 GRE 12 GB (2.7% ahead). These are different competitive brackets entirely.

The launch MSRP of 999 USD for the RTX 4080 SUPER versus 329 USD for the Arc A770 places them in separate market segments, and the benchmark data justifies that separation. The RTX 4080 SUPER is for users who need maximum performance in DX12, Vulkan, and OpenCL workloads without compromise. The Arc A770 is for those who prioritize memory capacity, display connectivity, and lower power draw while accepting a significant performance deficit. Based strictly on the recorded data, the choice hinges on whether the 50% to 64% performance gap matters more than the Arc A770's specific feature advantages.
