Where Each One Wins

The recorded data paints a clear picture: the RTX 4080 SUPER wins every head-to-head benchmark in the database. In 3DMark Steel Nomad DX12, it nearly doubles the A4500's score. In Geekbench Vulkan, it achieves exactly double the A4500's result (260,075 vs 129,980). Geekbench OpenCL also favors the 4080 SUPER by a substantial margin (219,065 vs 141,837).

However, the RTX A4500 wins in the context of its peer group. Its nearest rival, the RTX A4500 Mobile, scores 91,134, a delta of only 0.6%. The AMD Radeon Instinct MI60 scores 92,466, which is 0.9% higher. The A4500 beats the NVIDIA Quadro GP100 by 4.8% and the AMD Radeon PRO W7600 by 5.2%. This suggests the A4500 is positioned as a strong workstation card among its direct competitors.

The RTX 4080 SUPER, by contrast, sits in a tighter cluster. Its nearest rival, the RTX 4080, scores 54,247, essentially identical at -0.1%. The AMD Radeon Pro W5700X is 1.1% lower, and the AMD Radeon RX 6750 GRE 12 GB is 2.7% lower. The 4080 SUPER's average score of 54,209 is actually lower than all four of its listed nearest rivals, meaning it sits at the bottom of its immediate comparison group despite winning against the A4500.

For compute-heavy workloads with large memory footprints, the A4500's 20 GB capacity and higher percentile ranking suggest an edge in professional scenarios. For raw rendering speed and API-level performance, the 4080 SUPER dominates.

Architecture Differences

The two GPUs come from different architectural generations. The RTX A4500 uses the GA102 chip built on Ampere architecture, fabricated on Samsung's 8 nm process. The RTX 4080 SUPER uses the AD103 chip on Ada Lovelace architecture, fabricated on TSMC's 5 nm process. This node shrink is significant: the A4500 packs 28,300 million transistors on a 628 mm² die, while the 4080 SUPER fits 45,900 million transistors on a much smaller 379 mm² die. Transistor density tells the story: 45.1M per mm² for the A4500 versus 121.1M per mm² for the 4080 SUPER.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical. The RT core counts differ: 56 on the A4500 versus 80 on the 4080 SUPER. Tensor cores also differ, with 224 on the A4500 and 320 on the 4080 SUPER. These differences directly impact ray tracing and AI-accelerated workloads.

The A4500 uses GDDR6 memory, while the 4080 SUPER uses GDDR6X. The A4500 has a wider 320-bit bus, but the 4080 SUPER compensates with faster memory clocks and higher bandwidth. The A4500's memory runs at 2000 MHz (16 Gbps effective), while the 4080 SUPER's runs at 1438 MHz (23 Gbps effective).

Power delivery differs substantially. The A4500 has a 200 W TDP with a single 8-pin connector and a suggested PSU of 550 W. The 4080 SUPER has a 320 W TDP with a single 16-pin connector and a suggested PSU of 700 W. The 4080 SUPER is also physically larger: 310 mm long, 140 mm tall, and 61 mm wide, compared to the A4500's 267 mm length and 112 mm height. The A4500 is dual-slot, while the 4080 SUPER is triple-slot.

Head-to-Head Benchmarks

The database records three shared benchmarks between these two GPUs, and the RTX 4080 SUPER wins all three.

In 3DMark Steel Nomad DX12, the 4080 SUPER scores 6,600 against the A4500's 3,196. This is a delta of -51.6% from the A4500's perspective, meaning the A4500 delivers less than half the performance. This is the largest relative gap in the shared tests.

Geekbench OpenCL shows a closer but still decisive margin. The 4080 SUPER scores 219,065, while the A4500 scores 141,837. The delta is -35.3%. This test measures general compute performance across heterogeneous workloads, and the 4080 SUPER's advantage here is substantial but not as overwhelming as in DX12.

Geekbench Vulkan shows the 4080 SUPER at 260,075 versus the A4500 at 129,980. The delta is exactly -50%, meaning the 4080 SUPER doubles the A4500's Vulkan performance. This is notable because the A4500's Vulkan score is its lowest among the three benchmarks, while the 4080 SUPER's Vulkan score is its highest.

The wins are consistent across API types: DX12, OpenCL, and Vulkan all favor the 4080 SUPER. The A4500 has zero wins in the head-to-head comparison. The data suggests the 4080 SUPER's architectural advantages, particularly its higher boost clock (2550 MHz vs 1650 MHz) and more than double the FP32 throughput (52.22 TFLOPS vs 23.65 TFLOPS), translate directly into benchmark dominance.

The Verdict

The data is unambiguous on raw performance: the RTX 4080 SUPER wins every shared benchmark, with deltas ranging from -35.3% to -51.6%. Its FP32 compute is 120.8% higher, its texture rate is 120.8% higher, and its pixel rate is 80.3% higher. For anyone prioritizing maximum frame rates, rendering speed, or compute throughput, the 4080 SUPER is the clear choice based on these measurements.

The RTX A4500, however, has its own case. Its average benchmark score of 91,671 is 69.1% higher than the 4080 SUPER's 54,209. This discrepancy arises because the A4500's benchmark set includes different workloads, and its percentile ranking of 93 versus 86 reflects a broader comparison across all GPUs. The A4500 also offers 20 GB of memory, which is 25% more than the 4080 SUPER's 16 GB, and it does so at a lower TDP of 200 W versus 320 W. For large datasets or multi-GPU workstation configurations, the A4500's memory capacity and power efficiency could be decisive.

The A4500's nearest rivals are all workstation or prosumer cards, and it holds its own against them. The 4080 SUPER's nearest rivals are consumer and pro cards, and it sits at the lower end of that group. This suggests the 4080 SUPER is a strong consumer GPU that happens to beat an older workstation card, while the A4500 remains competitive within its professional niche.

The verdict depends on the workload. For gaming, real-time rendering, or any task where the 3DMark and Geekbench scores matter, the RTX 4080 SUPER is the data-backed winner. For professional compute with large memory requirements, the RTX A4500's higher percentile, larger memory pool, and lower power draw make it a defensible choice. The launch MSRP of 999 USD for the 4080 SUPER is the only listed price, and no MSRP is given for the A4500, so any cost comparison must rely on other factors. The data does not support a single universal winner; it supports two different tools for two different jobs.
