NVIDIA GeForce RTX 5080 vs NVIDIA RTX A4500 Mobile Comparison

Where Each One Wins

The recorded data splits these two NVIDIA parts into completely different performance universes. The RTX A4500 Mobile takes the professional mobile slot, while the RTX 5080 occupies the desktop enthusiast tier. Based on the benchmark results in the database, the RTX 5080 wins both recorded head-to-head tests, leaving the A4500 Mobile without a single victory in direct comparison.

The RTX A4500 Mobile still holds relevance in its own context. Its average benchmark score of 91134 places it at the 93rd percentile of all GPUs, which means it outperforms the vast majority of installed graphics hardware. The nearest rivals in the database include the desktop RTX A4500 at 91671 (just 0.6% higher), the AMD Radeon Instinct MI60 at 92466 (1.4% higher), the NVIDIA Quadro GP100 at 87445 (4.2% lower), and the AMD Radeon PRO W7600 at 87108 (4.6% lower). This clustering indicates the A4500 Mobile sits firmly in the upper mid-range of professional compute, trading blows with workstation cards rather than gaming parts.

The RTX 5080, by contrast, shows a lower average benchmark score of 56083, but this number reflects a different benchmark mix. Its percentile ranking is 87, slightly below the A4500 Mobile, yet the head-to-head results tell a very different story. The 5080's nearest rivals are all AMD gaming or workstation parts: the Radeon 8060S at 55757 (0.6% lower), the Radeon RX 6750 GRE 12 GB at 55698 (0.7% lower), the Radeon Pro W5700X at 54828 (2.3% lower), and the Radeon RX 9070 GRE at 57367 (2.2% higher). This suggests the 5080 competes in a dense pack of modern GPUs where small percentage differences separate many models.

The use-case split is clear from the data. The A4500 Mobile is built for mobile workstation workloads, with its 16 GB of GDDR6 memory and 512.0 GB/s bandwidth serving professional applications that need large memory pools. The 5080 targets high-end desktop gaming and content creation, with 16 GB of GDDR7 memory and 960.0 GB/s bandwidth, doubling the memory throughput. The A4500 Mobile draws 140 W, while the 5080 consumes 360 W, reflecting the mobile power envelope versus desktop unrestricted power delivery.

Architecture Differences

The architecture gap between these two GPUs spans two full generations of NVIDIA design. The RTX A4500 Mobile uses the GA104 chip on the Ampere architecture, built on an 8 nm process at Samsung. The RTX 5080 uses the GB203 chip on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. This process shrink from 8 nm to 5 nm, combined with the architectural leap, produces dramatic differences in transistor density. The A4500 Mobile packs 17,400 million transistors into a 392 mm² die, yielding 44.4M transistors per mm². The 5080 crams 45,600 million transistors into a slightly smaller 378 mm² die, achieving 120.6M transistors per mm², nearly triple the density.

The compute resources scale accordingly. The A4500 Mobile carries 5888 shading units, 184 texture mapping units, and 96 raster operation units. The 5080 more than doubles the shading units to 10752, nearly doubles the TMUs to 336, and raises the ROPs to 112. Ray tracing cores jump from 46 on the A4500 Mobile to 84 on the 5080, and tensor cores go from 184 to 336. These raw resource counts explain why the 5080 delivers such a massive compute advantage in the benchmark data.

Clock speeds also differ substantially. The A4500 Mobile runs at a 930 MHz base and 1500 MHz boost, reflecting its mobile power constraints. The 5080 starts at 2295 MHz base and boosts to 2617 MHz, a 75% higher boost clock. Memory clocks follow the same pattern: the A4500 Mobile uses 2000 MHz with 16 Gbps effective, while the 5080 runs at 1875 MHz with 30 Gbps effective, nearly doubling the effective data rate. The memory bus width stays identical at 256 bit for both, but the GDDR7 memory on the 5080 pushes bandwidth from 512.0 GB/s to 960.0 GB/s.

The interface and connectivity also differ. The A4500 Mobile uses PCIe 4.0 x16, while the 5080 uses PCIe 5.0 x16, doubling the potential host bandwidth. Display outputs on the A4500 Mobile are described as portable device dependent, whereas the 5080 offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. The 5080 requires a 16-pin power connector and a 750 W suggested power supply, while the A4500 Mobile lists no power connectors, operating entirely within its 140 W mobile envelope.

Head-to-Head Benchmarks

The database records exactly two head-to-head benchmark comparisons between these GPUs, and the RTX 5080 wins both by substantial margins. In the Geekbench OpenCL test, the A4500 Mobile scores 105307 while the 5080 reaches 235901, giving the 5080 a 55.4% advantage. This is more than double the raw compute score, reflecting the 5080's far higher FP32 throughput of 56.28 TFLOPS versus 17.66 TFLOPS on the A4500 Mobile.

The Geekbench Vulkan test shows an even larger gap. The A4500 Mobile scores 76960, while the 5080 posts 255450, a 69.9% difference. The Vulkan result demonstrates that the 5080's architectural improvements extend beyond raw compute into graphics API efficiency. The 5080's 293.1 GPixel/s pixel rate and 879.3 GTexel/s texture rate dwarf the A4500 Mobile's 144.0 GPixel/s and 276.0 GTexel/s, explaining the graphics benchmark dominance.

Looking at the broader benchmark suite available only for the 5080, the data shows consistent performance across different tests. The Passmark G3D score of 36565 and GPU compute score of 21789 indicate strong general-purpose and compute performance. The 3DMark Steel Nomad DX12 score of 8637 provides a modern gaming workload reference. The 5080's Passmark DirectX scores range from 151 for DirectX 12 to 389 for DirectX 9, with DirectX 10 at 208 and DirectX 11 at 324. The G2D score of 1415 rounds out the 2D performance picture.

The average benchmark scores in the database require careful interpretation. The A4500 Mobile's average of 91134 comes from only two benchmarks (OpenCL and Vulkan), both of which are compute-oriented and favor workstation cards with high FP32 throughput. The 5080's average of 56083 includes ten benchmarks, several of which are gaming-focused Passmark tests that produce lower absolute numbers. This explains why the A4500 Mobile has a higher average score despite losing both head-to-head tests: the benchmark composition differs, not the underlying performance.

FAQ

The Verdict

The data directs a clear choice for anyone prioritizing raw performance: the RTX 5080 is the dominant part in every recorded head-to-head metric. Its 55.4% OpenCL lead and 69.9% Vulkan lead over the A4500 Mobile leave no ambiguity about which GPU delivers more compute power. The 5080's FP32 throughput of 56.28 TFLOPS versus 17.66 TFLOPS, combined with double the memory bandwidth, explains the benchmark results completely.

The A4500 Mobile still serves a distinct purpose in the database. Its 93rd percentile ranking and average score of 91134 place it among the top professional mobile GPUs, and its nearest rivals are all workstation or compute-oriented cards. The 16 GB memory capacity matches the 5080, making it suitable for large datasets, but the 512.0 GB/s bandwidth and 17.66 TFLOPS compute limit its ceiling compared to the 5080.

For desktop users building high-end systems, the 5080 is the obvious choice based on the recorded data. Its 360 W power draw and 750 W suggested PSU are substantial, but the performance return justifies the power envelope. The 5080's density advantage, with 120.6M transistors per mm² versus 44.4M, shows how much more efficient the Blackwell architecture is compared to Ampere.

For mobile workstation users, the A4500 Mobile remains a capable option within its 140 W envelope. The data shows it competes with desktop Quadro and Radeon Pro parts, and its end-of-life status means it should still be available in existing mobile workstations. The 5080 cannot replace it in a laptop form factor, as the 5080's dual-slot design, 304 mm length, and 360 W power draw are clearly desktop-oriented.
