NVIDIA RTX 6000D vs NVIDIA RTX A4500 Mobile Comparison

Where Each One Wins

The recorded data splits these two NVIDIA workstation parts into entirely different performance classes. The NVIDIA RTX 6000D wins the only shared benchmark in the database, the Geekbench OpenCL test, by a decisive margin. That single win reflects a desktop-class monster built for sustained, high-throughput compute. The RTX A4500 Mobile, by contrast, has no benchmark wins against the RTX 6000D, but it occupies a different niche entirely: it is a mobile part with a 140 W TDP, designed for portable workstations where the RTX 6000D's 600 W envelope and dual-slot cooler are physically impossible.

The use-case split is clear from the architecture and form factor. The RTX 6000D is a dual-slot, 304 mm long desktop card with a 16-pin power connector and a suggested 1000 W PSU. It targets fixed installations: render farms, AI training nodes, and simulation clusters where power delivery and cooling are non-issues. The RTX A4500 Mobile has no fixed dimensions, no power connectors of its own, and draws power from the host laptop. It targets field work, on-site visualization, and any scenario where a full-size desktop GPU cannot travel.

Benchmark percentiles reinforce the gap. The RTX 6000D sits at the 98th percentile against all GPUs in the database, while the RTX A4500 Mobile sits at the 93rd. That five-point difference is meaningful, but it also shows that the mobile part is not a slouch; it still outperforms the vast majority of graphics hardware ever recorded. The database's average benchmark scores make the chasm explicit: the RTX 6000D averages 195,964, the RTX A4500 Mobile averages 91,134. The desktop card delivers roughly 2.15 times the average score, which aligns with the 268.8% delta observed in the head-to-head OpenCL test.

In practical terms, the RTX 6000D wins any workload where raw FP32 throughput, memory bandwidth, or VRAM capacity is the bottleneck. The RTX A4500 Mobile wins any workload where the GPU must fit inside a laptop chassis and run off battery or a modest AC adapter. There is no overlap in their intended deployment environments.

Architecture Differences

The two GPUs come from different architectural generations and different foundries. The RTX 6000D uses the GB202 chip, built on Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. The RTX A4500 Mobile uses the GA104 chip, built on Ampere architecture, fabricated on Samsung's 8 nm process. The process node gap is significant: 5 nm versus 8 nm. The transistor counts reflect the scale difference. The RTX 6000D packs 92,200 million transistors on a 750 mm² die, yielding a density of 122.9 million transistors per square millimeter. The RTX A4500 Mobile has 17,400 million transistors on a 392 mm² die, at 44.4 million per square millimeter. The desktop chip is roughly 5.3 times the transistor count and almost double the die area.

Memory subsystems diverge completely. The RTX 6000D ships with 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The RTX A4500 Mobile ships with 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s. The capacity difference is 5.25 times, the bandwidth difference is 2.73 times. The RTX 6000D's memory clock runs at 1560 MHz with 25 Gbps effective data rate; the mobile part runs at 2000 MHz with 16 Gbps effective. The desktop card uses the newer memory standard and a wider bus.

Compute resources tell a similar story. The RTX 6000D has 19,968 shading units, 624 texture mapping units, 192 ROPs, 156 ray tracing cores, and 624 tensor cores. The RTX A4500 Mobile has 5,888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The desktop card leads by 3.39 times in shaders, 3.39 times in TMUs, 2 times in ROPs, 3.39 times in RT cores, and 3.39 times in tensor cores.

Clock speeds also favor the desktop part. The RTX 6000D runs at 1992 MHz base and 2430 MHz boost. The RTX A4500 Mobile runs at 930 MHz base and 1500 MHz boost. The boost clock difference is 1.62 times. Combined with the shader count, the FP32 throughput gap is enormous: 97.04 TFLOPS for the desktop card versus 17.66 TFLOPS for the mobile part, a 5.49 times difference. The same ratio applies to FP16, since both run at 1:1.

The RTX 6000D uses PCIe 5.0 x16, while the RTX A4500 Mobile uses PCIe 4.0 x16. Display outputs differ by design: the desktop card has four DisplayPort 2.1b connectors, the mobile part's outputs are portable-device dependent. Power delivery is the most telling difference: the RTX 6000D requires a 600 W TDP and a dedicated 16-pin connector, the RTX A4500 Mobile has a 140 W TDP and no power connectors of its own.

Head-to-Head Benchmarks

The database contains one direct comparison between these two GPUs: the Geekbench OpenCL test. The RTX 6000D scored 388,405, the RTX A4500 Mobile scored 105,307. The delta is 268.8% in favor of the desktop card. That means the RTX 6000D delivers roughly 3.69 times the OpenCL score of the mobile part. The margin is consistent with the raw specification gap: 5.49 times the FP32 throughput, 2.73 times the memory bandwidth, and 5.25 times the VRAM capacity. The benchmark result is lower than the theoretical compute ratio, which suggests memory latency or driver overhead on the mobile part, but the outcome is never in doubt.

The RTX 6000D also has a Steel Nomad DX12 score of 3,522 in the database, though the RTX A4500 Mobile has no comparable DirectX 12 result recorded. That absence prevents a direct gaming or DX12 workload comparison, but the OpenCL result is representative of compute performance, which is the primary use case for both cards.

Against its nearest rivals, the RTX 6000D shows a tight cluster. Its average score of 195,964 sits 0.8% above the Tesla V100S PCIe 32 GB, 4.7% above the A100 SXM4 40 GB, and 6.1% above the RTX 5000 Ada Generation. It trails the A100 PCIe 80 GB by 5.4%. These are single-digit percentage swings, meaning the RTX 6000D lands squarely in the same performance tier as those enterprise accelerators, despite its different architecture.

The RTX A4500 Mobile's nearest rivals show a similarly tight grouping. Its average score of 91,134 is 0.6% below the desktop RTX A4500, 1.4% below the AMD Radeon Instinct MI60, 4.2% above the Quadro GP100, and 4.6% above the Radeon PRO W7600. The mobile part essentially matches its desktop sibling, which is a notable achievement for a 140 W laptop GPU, but it operates in a completely different league from the RTX 6000D.

The Verdict

The data supports a straightforward allocation. The RTX 6000D is the choice for any stationary workstation or server where maximum compute throughput is the priority. Its 97.04 TFLOPS FP32, 1.40 TB/s memory bandwidth, and 84 GB VRAM make it suitable for large-scale AI training, scientific simulation, and high-resolution rendering. The 98th percentile ranking and the 268.8% OpenCL lead over the mobile part confirm that it is a top-tier accelerator by any measure.

The RTX A4500 Mobile is the choice for professionals who need a capable workstation GPU in a portable form factor. Its 93rd percentile ranking shows it outperforms the vast majority of GPUs, and its 17.66 TFLOPS FP32 and 512.0 GB/s bandwidth are respectable for a 140 W mobile part. The fact that it lands within 0.6% of the desktop RTX A4500 in average score suggests the mobile implementation does not sacrifice much versus its desktop sibling.

There is no scenario where these two cards compete directly. The RTX 6000D is marked as Active production, released in 2025, with a launch MSRP of 8,565 USD. The RTX A4500 Mobile is End-of-life, released in 2022, with a successor in Ada-MW. Anyone considering a purchase should decide based on physical deployment first: if the workload travels, the mobile part is the only option; if it stays in a lab or server room, the RTX 6000D dominates on every measured axis. The database records one clear winner in raw performance, and one clear winner in portability. Neither metric is negotiable given the hardware constraints.
