NVIDIA GeForce RTX 4080 SUPER vs NVIDIA RTX A6000 Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity in direct comparisons: the NVIDIA GeForce RTX 4080 SUPER wins all nine head-to-head benchmark matchups against the NVIDIA RTX A6000. The largest margin appears in Geekbench Vulkan, where the RTX 4080 SUPER scores 260,075 versus the A6000's 164,462, a 58.1% advantage. That gap reflects a generational shift in graphics API efficiency, not a marginal tweak.

Passmark DirectX 11 shows a similar story: 301 for the RTX 4080 SUPER versus 191 for the A6000, a 57.6% delta. DirectX 12 follows at 54% (134 versus 87), and DirectX 9 lands at 55.5% (381 versus 245). The older API results are especially striking because they suggest the RTX 4080 SUPER's architectural advantages carry backward compatibility well, rather than being optimized only for modern workloads.

In Passmark G3D, the RTX 4080 SUPER posts 34,245 against the A6000's 22,577, a 51.7% lead. The compute-oriented Passmark GPU Compute test shows 19,822 versus 14,110, a 40.5% edge. Even 2D performance favors the newer card: Passmark G2D scores 1,270 versus 913, a 39.1% gap. DirectX 10 rounds out the sweep at 24.5% (193 versus 155).

Geekbench OpenCL is the closest contest on the board, with the RTX 4080 SUPER scoring 219,065 versus 193,937, a 13% lead. That smaller margin makes sense given the A6000's higher shading unit count and wider memory bus, which narrow the gap in raw compute throughput. Still, the RTX 4080 SUPER takes the win.

The average benchmark scores reinforce the pattern: the RTX 4080 SUPER sits at 54,209, while the A6000 averages 44,075. The RTX 4080 SUPER also ranks in the 86th percentile among all GPUs, versus the 84th percentile for the A6000. Notably, the RTX 4080 SUPER's nearest rival by average score is the RTX 4080 at 54,247 (delta of -0.1%), while the A6000's closest competitor is the RTX 4070 Ti at 44,795 (delta of -1.6%). The RTX 4080 SUPER essentially trades blows with its non-Super sibling, while the A6000 sits in a lower performance tier entirely.

Architecture Differences

The two cards come from different manufacturing nodes and design philosophies. The RTX 4080 SUPER uses the AD103 chip on TSMC's 5 nm process, while the RTX A6000 relies on the GA102 die fabricated by Samsung on 8 nm. That process gap is fundamental: the RTX 4080 SUPER packs 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1M per mm². The A6000's GA102 holds 28,300 million transistors across a much larger 628 mm² die, for a density of just 45.1M per mm².

Clock speeds amplify the difference. The RTX 4080 SUPER runs at a 2,295 MHz base and 2,550 MHz boost, while the A6000 operates at 1,410 MHz base and 1,800 MHz boost. Higher clocks plus denser silicon explain why the RTX 4080 SUPER achieves 52.22 TFLOPS FP32 and FP16 (1:1), versus 38.71 TFLOPS for the A6000 on both precision levels. The RTX 4080 SUPER also delivers higher pixel and texture rates: 285.6 GPixel/s and 816.0 GTexel/s, compared to 201.6 GPixel/s and 604.8 GTexel/s for the A6000.

Memory configurations differ sharply. The RTX 4080 SUPER has 16 GB of GDDR6X on a 256-bit bus, providing 736.3 GB/s of bandwidth. The A6000 offers 48 GB of GDDR6 on a 384-bit bus, with 768.0 GB/s of bandwidth. The A6000's capacity advantage is massive, but its bandwidth lead is modest at roughly 4%. The RTX 4080 SUPER's memory runs at 1,438 MHz (23 Gbps effective), while the A6000's memory is clocked at 2,000 MHz (16 Gbps effective).

Shader and accelerator counts favor the A6000 in raw numbers: 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The RTX 4080 SUPER has 10,240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. Yet the RTX 4080 SUPER still outperforms across every benchmark, showing that Ada Lovelace's architectural efficiency outweighs Ampere's wider configuration.

Power envelopes are close: the RTX 4080 SUPER is rated at 320 W, the A6000 at 300 W. Both suggest a 700 W power supply. The RTX 4080 SUPER uses a single 16-pin connector and occupies a triple-slot footprint, while the A6000 uses an 8-pin EPS connector and fits in a dual-slot design. The A6000 is shorter at 267 mm versus 310 mm for the RTX 4080 SUPER.

Where Each One Wins

The RTX 4080 SUPER wins every measured benchmark category, so the practical split comes down to workload characteristics that the data implies rather than direct victories. For real-time rendering, DirectX 12 and Vulkan workloads, the RTX 4080 SUPER is decisively ahead. Its 58.1% Vulkan lead and 54% DirectX 12 lead make it the clear choice for gaming, ray tracing, and applications built on modern graphics APIs. The 52.22 TFLOPS FP32 throughput also supports heavy compute tasks, though the A6000's 48 GB frame buffer remains unmatched for memory-bound scenarios.

The RTX A6000's win condition is capacity, not speed. Its 48 GB of GDDR6 on a 384-bit bus means it can hold datasets, models, and scenes that would exceed the RTX 4080 SUPER's 16 GB. For AI inference with large batch sizes, machine learning training on big models, or visual effects work with massive texture sets, the A6000's memory pool is the deciding factor. The bandwidth difference favors the A6000 slightly, but at 768.0 GB/s versus 736.3 GB/s, the practical gain is small.

For compute workloads that fit within 16 GB, the RTX 4080 SUPER is faster across the board. Passmark GPU Compute shows a 40.5% advantage, and Geekbench OpenCL confirms a 13% lead. The A6000's lower clock speeds and older architecture put it behind in raw throughput, even with more shading units. The RTX 4080 SUPER also wins in legacy DirectX 9 and DirectX 10 tests, which matters for compatibility with older software stacks.

Physical design favors the A6000 for cramped workstations: dual-slot width, 267 mm length, and 112 mm height versus the RTX 4080 SUPER's triple-slot, 310 mm length, and 140 mm height. The A6000's 8-pin EPS connector is also more common in professional systems than the RTX 4080 SUPER's 16-pin connector, although both list a 700 W suggested power supply.
