NVIDIA GeForce RTX 4080 SUPER vs NVIDIA RTX A4500 Mobile Comparison

The recorded data places the NVIDIA GeForce RTX 4080 SUPER clearly ahead of the NVIDIA RTX A4500 Mobile in every shared benchmark, but the gap is not uniform. In Geekbench OpenCL, the RTX 4080 SUPER scores 219,065 against 105,307 for the A4500 Mobile, a delta of 51.9% in favor of the desktop card. The Vulkan result is even more lopsided: 260,075 versus 76,960, meaning the RTX 4080 SUPER leads by 70.4%. These are the only two head-to-head tests in the database, and the A4500 Mobile wins none of them. The A4500 Mobile’s average benchmark score is 91,134, while the RTX 4080 SUPER averages 54,209, but that overall figure is dragged down by the RTX 4080 SUPER’s inclusion of many additional tests (Passmark suites) where the A4500 Mobile has no recorded data. For the tests both share, the RTX 4080 SUPER is decisively faster, with the Vulkan margin nearly three times the OpenCL margin. The A4500 Mobile’s percentile rank among all GPUs is 93, higher than the RTX 4080 SUPER’s 86, but that percentile reflects a broader set of workloads, not these direct comparisons. In the shared metrics, the RTX 4080 SUPER’s shading units (10,240 versus 5,888) and boost clock (2550 MHz versus 1500 MHz) explain the raw compute advantage, while its memory bandwidth of 736.3 GB/s versus 512.0 GB/s feeds that compute more rapidly. The delta percentages are stark, but they also indicate that the A4500 Mobile is not a weak part in absolute terms; it sits within 0.6% of the desktop NVIDIA RTX A4500 in average score, and it beats the NVIDIA Quadro GP100 by 4.2% and the AMD Radeon PRO W7600 by 4.6%. The RTX 4080 SUPER, by contrast, is just 0.1% behind the original RTX 4080 and trails the AMD Radeon Pro W5700X by 1.1%, showing that its performance tier is tightly packed.

Head-to-Head Benchmarks

The data shows a two-test comparison, and the RTX 4080 SUPER dominates both. In Geekbench OpenCL, the RTX 4080 SUPER scores 219,065, which is 108.0% higher than the A4500 Mobile’s 105,307; the recorded delta is 51.9%, meaning the A4500 Mobile performs at roughly half the OpenCL level. In Geekbench Vulkan, the RTX 4080 SUPER reaches 260,075, while the A4500 Mobile manages 76,960, a delta of 70.4%. That Vulkan gap is severe: the RTX 4080 SUPER delivers more than three times the A4500 Mobile’s score. The A4500 Mobile’s own Vulkan score of 76,960 is lower than its OpenCL score of 105,307, suggesting that its compute architecture is less optimized for Vulkan’s API overhead. The RTX 4080 SUPER shows the opposite trend, with its Vulkan score (260,075) exceeding its OpenCL score (219,065) by 18.7%, indicating strong driver and hardware support for modern graphics APIs. For context, the A4500 Mobile’s average benchmark score of 91,134 is close to its nearest rival, the NVIDIA RTX A4500 (91,671, a 0.6% delta), and it outpaces the AMD Radeon Instinct MI60 by 1.4% in that average. The RTX 4080 SUPER’s average score of 54,209 is within 0.1% of the RTX 4080 (54,247), but its nearest rivals include lower-tier cards like the AMD Radeon RX 6750 GRE 12 GB (55,698, a 2.7% delta) and the AMD Radeon 8060S (55,757, a 2.8% delta), which actually score higher on average. That inversion happens because the RTX 4080 SUPER’s Passmark results (for example, Passmark G3D at 34,245 and Passmark GPU Compute at 19,822) are weighted alongside its much higher Geekbench scores, while the A4500 Mobile has no Passmark data to dilute its average. In the head-to-head tests, the verdict is unambiguous: the RTX 4080 SUPER wins every shared benchmark, with the Vulkan test being its strongest relative showing.

Architecture Differences

The two GPUs come from different design generations and foundries. The RTX A4500 Mobile uses the GA104 chip on Samsung’s 8 nm process, with 17,400 million transistors on a 392 mm² die, yielding a transistor density of 44.4 million per square millimeter. The RTX 4080 SUPER uses the AD103 chip on TSMC’s 5 nm node, packing 45,900 million transistors into a smaller 379 mm² die, for a density of 121.1 million per square millimeter. That density advantage is critical; the RTX 4080 SUPER fits nearly 2.6 times the transistor count into a slightly smaller area. The A4500 Mobile is built on the Ampere architecture, while the RTX 4080 SUPER uses Ada Lovelace. Clock speeds differ substantially: the A4500 Mobile runs at a 930 MHz base and 1500 MHz boost, whereas the RTX 4080 SUPER boosts to 2550 MHz from a 2295 MHz base. Memory technology also diverges: the A4500 Mobile uses GDDR6 at 16 Gbps effective on a 256-bit bus, delivering 512.0 GB/s, while the RTX 4080 SUPER uses GDDR6X at 23 Gbps effective on the same 256-bit bus, reaching 736.3 GB/s. Both cards have 16 GB of memory, but the RTX 4080 SUPER’s faster memory gives it a 43.8% bandwidth advantage. The compute resources are not comparable: the A4500 Mobile has 5,888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The RTX 4080 SUPER has 10,240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. That is 74% more shading units, 74% more TMUs, 17% more ROPs, 74% more RT cores, and 74% more tensor cores. Pixel rate scales accordingly: 144.0 GPixel/s for the A4500 Mobile versus 285.6 GPixel/s for the RTX 4080 SUPER, almost exactly double. Texture rate is 276.0 GTexel/s versus 816.0 GTexel/s, a 196% difference. FP32 compute is 17.66 TFLOPS for the A4500 Mobile and 52.22 TFLOPS for the RTX 4080 SUPER, a 196% gap that matches the texture rate difference. FP16 is identical to FP32 on both cards (1:1 ratio), so the same relative performance applies. The A4500 Mobile has no power connectors listed and a 140 W TDP, while the RTX 4080 SUPER requires a 16-pin connector, has a 320 W TDP, and suggests a 700 W power supply. The RTX 4080 SUPER is a triple-slot card measuring 310 mm by 140 mm by 61 mm, whereas the A4500 Mobile is portable-device dependent with no fixed dimensions. Display outputs also differ: the A4500 Mobile is portable-device dependent, while the RTX 4080 SUPER offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A4500 Mobile was released on 2022-03-21 and is marked end-of-life, with its predecessor listed as Quadro Turing-M and successor as Ada-MW. The RTX 4080 SUPER released on 2024-01-30, also end-of-life, with predecessor GeForce 30 and successor GeForce 50. The RTX 4080 SUPER has a launch MSRP of 999 USD.

Where Each One Wins

The RTX 4080 SUPER wins every shared benchmark, so its strengths are clear. It leads in Geekbench OpenCL by 51.9% and in Geekbench Vulkan by 70.4%. The data indicates it is the faster compute part for both general-purpose and graphics-API workloads. Its memory bandwidth (736.3 GB/s) and FP32 throughput (52.22 TFLOPS) are roughly triple the A4500 Mobile’s figures, so any task that scales with raw shader or memory throughput will favor the RTX 4080 SUPER. The RTX 4080 SUPER also has more RT cores (80 versus 46) and tensor cores (320 versus 184), which suggests better ray tracing and AI acceleration, although no dedicated ray-tracing benchmark is in the shared data. The RTX 4080 SUPER’s pixel rate of 285.6 GPixel/s versus 144.0 GPixel/s means it can fill more pixels per second, a benefit for high-resolution rendering. The A4500 Mobile, despite losing the head-to-head, still has strengths within its own context. Its average benchmark score (91,134) is much higher than the RTX 4080 SUPER’s (54,209), because the A4500 Mobile’s two Geekbench results are both strong. Its percentile rank (93) exceeds the RTX 4080 SUPER’s (86), meaning it sits in a higher tier when compared against all GPUs in the database. The A4500 Mobile’s nearest rivals include the desktop RTX A4500 (within 0.6%) and the AMD Radeon PRO W7600 (4.6% ahead), showing it competes well with professional desktop parts. Its 140 W TDP and lack of power connectors make it suitable for portable devices, where the RTX 4080 SUPER’s 320 W TDP and triple-slot design would be impractical. The A4500 Mobile’s GDDR6 memory is slower than GDDR6X, but its 512.0 GB/s bandwidth is still substantial. For workloads that are limited by driver overhead rather than raw compute, the A4500 Mobile’s higher average score suggests better optimization in certain legacy or compute-heavy contexts, though the direct comparisons do not show this.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4080 SUPER is the faster GPU in every shared benchmark. It outperforms the RTX A4500 Mobile by 51.9% in OpenCL and 70.4% in Vulkan, with its higher shading unit count, faster clocks, and greater memory bandwidth providing the underlying basis. For any user prioritizing raw compute performance, the RTX 4080 SUPER is the clear choice, provided the system can accommodate its 320 W TDP, triple-slot footprint, and 16-pin power requirement. The RTX 4080 SUPER also offers more RT cores, more tensor cores, and faster GDDR6X memory, which positions it better for modern graphics workloads that use ray tracing or AI features, although those specific workloads are not in the shared test set. The RTX A4500 Mobile, however, is not a poor performer. Its average benchmark score of 91,134 is far higher than the RTX 4080 SUPER’s 54,209, and its 93rd percentile rank versus the 86th percentile shows it excels in a broader database context. Its 140 W TDP and portable-device-dependent design make it the only viable option for laptops or compact systems where the RTX 4080 SUPER cannot physically fit. The A4500 Mobile’s nearest rivals are professional desktop cards like the RTX A4500 and AMD Radeon PRO W7600, indicating it belongs to a workstation-oriented tier, whereas the RTX 4080 SUPER sits among gaming and prosumer parts, with rivals like the RX 6750 GRE and Radeon 8060S scoring slightly higher on average. In short, the RTX 4080 SUPER wins on pure speed and modern architecture, while the A4500 Mobile wins on portability, efficiency, and average benchmark standing across the full database. The choice depends on whether the priority is maximum compute in a desktop chassis or professional-grade performance in a mobile form factor. The recorded data does not support a third option: for the two tests both cards run, the RTX 4080 SUPER is always ahead, and by a wide margin.
