NVIDIA RTX A4500 Mobile

The NVIDIA RTX A4500 Mobile is an end-of-life Ampere-generation laptop GPU built on Samsung’s 8 nm process, featuring 5,888 shading units, 46 RT cores, and 184 tensor cores. Its average benchmark score of 91,134 places it in the 95th percentile of all GPUs, meaning it outperforms the vast majority of installed graphics hardware. The data shows a mobile part that sits at the top of the laptop stack, though it faces stiff competition from a few desktop and mobile heavyweights.

How It Compares

vs. AMD Radeon RX 7900M: The RTX A4500 Mobile trails the RX 7900M by a razor-thin 0.6% in average benchmark score (91,134 vs. 91,713). This is effectively a statistical tie, indicating that in raw compute terms, the two GPUs are indistinguishable in most workloads. The A4500 Mobile’s 16 GB GDDR6 memory and 512.0 GB/s bandwidth give it a capacity advantage, but the RX 7900M matches it in throughput, making the choice between them dependent on software ecosystem rather than raw performance.

vs. NVIDIA RTX A4500 (desktop): The mobile variant is 1.1% slower than its desktop namesake (91,134 vs. 92,145). This is a remarkably small gap for a laptop part, suggesting that the mobile implementation runs at near-desktop clocks under sustained load. The desktop version shares the same GA104 chip and 16 GB GDDR6 configuration, so the delta likely comes from thermal and power constraints rather than architectural differences.

vs. AMD Radeon Pro VII: The A4500 Mobile leads the Radeon Pro VII by 2.4% (91,134 vs. 88,961). The Pro VII is a workstation-oriented card with a different memory setup, but the benchmark scores show the A4500 Mobile pulling ahead in mixed compute tasks. This margin is consistent across synthetic workloads, indicating a genuine performance advantage rather than a single-test anomaly.

vs. NVIDIA Quadro GP100: The A4500 Mobile outperforms the Quadro GP100 by 2.9% (91,134 vs. 88,528). The GP100 is an older Pascal-generation part with different compute characteristics, but the data clearly shows the A4500 Mobile delivering higher average performance. The gap is modest, yet it holds across the benchmark suite, reinforcing the A4500 Mobile’s position as a modern upgrade.

Memory Subsystem

The RTX A4500 Mobile comes with 16 GB of GDDR6 memory on a 256-bit bus, yielding 512.0 GB/s of bandwidth. This configuration is substantial for a laptop GPU, allowing high-resolution textures and large datasets to reside in VRAM without spilling to system memory. For 4K gaming, the 16 GB capacity is more than sufficient for current titles, even with ultra-quality texture packs, which often exceed 10 GB in demanding scenes.

The 512.0 GB/s bandwidth is the critical figure for high-resolution performance. At 4K, pixel throughput demands rise sharply, and the memory subsystem must feed the 5,888 shading units and 184 TMUs without stalling. The data shows a texture rate of 276.0 GTexel/s and a pixel rate of 144.0 GPixel/s, both of which are well-served by this bandwidth. In practice, this means the GPU can sustain high frame rates at 1440p and remains playable at 4K with adjusted settings, though it will not match the raw bandwidth of desktop parts with wider buses.

The 16 GB capacity also benefits professional workloads such as 3D rendering or machine learning inference, where model weights and scene data often exceed 8 GB. The GDDR6 type is not as fast as GDDR6X or HBM, but the 256-bit bus compensates, delivering a balanced memory profile that avoids the bottlenecks seen in narrower-bus competitors.

Who Should Consider It

The benchmark data suggests the RTX A4500 Mobile is best suited for users who need desktop-class compute in a portable chassis. With a 95th percentile ranking and an average score of 91,134, it handles 1440p gaming at high-to-ultra settings with ease, and it can manage 4K at medium-to-high settings in most titles. The 16 GB VRAM future-proofs it against upcoming games that target 4K textures, making it a viable choice for a laptop intended to last several years.

For creators and professionals, the 46 RT cores and 184 tensor cores accelerate ray-traced rendering and AI-assisted workflows, respectively. The FP32 throughput of 17.66 TFLOPS (with matching FP16 at 1:1 ratio) indicates strong compute capability for video editing, 3D modeling, and scientific simulations. Users who require CUDA acceleration will find this GPU far more capable than consumer laptop parts, as it maintains its performance lead over the Radeon Pro VII by 2.4% and the Quadro GP100 by 2.9%.

Conversely, those who prioritize battery life or silent operation should look elsewhere. The 140 W TDP is high for a mobile GPU, and the data implies sustained performance comes at the cost of heat and fan noise. Gamers who play only esports titles at 1080p will be over-served by this hardware, as its capabilities are wasted on low-resolution, low-detail workloads.

Benchmark Performance

The RTX A4500 Mobile delivers an average benchmark score of 91,134, placing it in the 95th percentile of all GPUs. This is a strong result for a mobile part, but the nearestRivals data reveals a tight cluster at this performance level. The AMD Radeon RX 7900M leads by just 0.6% (91,713 vs. 91,134), a margin that falls well within run-to-run variance. The desktop RTX A4500 is 1.1% faster (92,145 vs. 91,134), while the AMD Radeon Pro VII trails by 2.4% (88,961 vs. 91,134), and the NVIDIA Quadro GP100 is 2.9% behind (88,528 vs. 91,134).

In synthetic tests, the GPU scores 105,307 in Geekbench OpenCL and 76,960 in Geekbench Vulkan. The OpenCL score is notably higher, reflecting the GPU’s compute-oriented architecture with 5,888 shading units and 184 tensor cores. The Vulkan score, while lower, still demonstrates solid graphics performance, though it suggests the driver stack favors compute workloads over gaming-specific API calls. This disparity is typical for workstation-oriented GPUs, which prioritize FP32 throughput (17.66 TFLOPS) over gaming optimizations.

The delta percentages against rivals indicate that the A4500 Mobile is not the absolute fastest mobile GPU, but it is within 1% of the top competitor. The 2.4% lead over the Radeon Pro VII and 2.9% over the Quadro GP100 show that it comfortably beats older professional parts, making it a sensible upgrade for users coming from those generations. The 0.6% gap to the RX 7900M is negligible in practice; users should base their choice on software compatibility and driver maturity rather than benchmark scores.

Power and Cooling

The RTX A4500 Mobile has a TDP of 140 W, which is substantial for a laptop GPU. This power envelope allows the GA104 chip to boost to 1500 MHz from a 930 MHz base clock, but it also means the cooling solution must be robust to sustain that boost frequency under load. The data does not specify a suggested PSU, as this is a mobile part that relies on the laptop’s power delivery system rather than an external power supply.

The power connectors are listed as “None,” confirming that the GPU draws power through the motherboard’s dedicated VRM circuitry, not through supplementary PCIe power cables. For users considering a laptop with this GPU, the practical implication is that the system will require a high-capacity AC adapter and a cooling design capable of dissipating 140 W of heat. The 8 nm process from Samsung is less efficient than newer nodes, so thermal management is critical; sustained workloads may cause clock throttling if the cooling solution is inadequate.

Given the end-of-life status and 140 W TDP, this GPU is best suited for thick, heavy laptops with aggressive cooling, not ultrabooks. The PCIe 4.0 x16 interface provides ample bandwidth for the GPU’s data transfer needs, and the “Portable Device Dependent” display outputs mean the specific ports vary by laptop model. Users should verify that their chosen laptop’s power delivery and cooling can handle the 140 W TDP, as this is the single most important factor in achieving the benchmark scores shown in the data.
