NVIDIA RTX 6000 Ada Generation vs NVIDIA RTX A4500 Mobile Comparison

Where Each One Wins

The recorded benchmark data is unambiguous: the NVIDIA RTX 6000 Ada Generation wins both head-to-head tests, with no wins recorded for the RTX A4500 Mobile. In Geekbench OpenCL, the RTX 6000 Ada scores 311,629 against 105,307 for the mobile part, a 195.9% advantage. In Geekbench Vulkan, the gap widens further: 262,845 versus 76,960, a 241.5% delta. The desktop Ada card is not merely faster; it dominates in both compute APIs tested.

The RTX A4500 Mobile, by contrast, is a different class of device. Its average benchmark score of 91,134 places it at the 93rd percentile of all GPUs, which is respectable for a mobile workstation part. However, the RTX 6000 Ada's average score of 287,237 puts it at the 99th percentile. That six-point percentile gap translates into a roughly threefold difference in raw compute throughput. The mobile card's nearest rivals include the desktop RTX A4500 (delta -0.6%) and the AMD Instinct MI60 (delta -1.4%), meaning it sits in a performance tier alongside older desktop accelerators. The RTX 6000 Ada, meanwhile, trades blows with the NVIDIA L40S (delta -2.9%) and sits just 1.1% above the L40. These are entirely different performance strata.

If the workload is OpenCL-heavy, the RTX 6000 Ada delivers nearly triple the score of the mobile part. If the workload leans on Vulkan, the desktop card's lead is even more pronounced. The A4500 Mobile does not win any category in the database. For users who need maximum compute in a fixed workstation, the RTX 6000 Ada is the clear choice. For those constrained to a laptop chassis, the A4500 Mobile is the only option in this comparison, but its performance ceiling is far lower.

Architecture Differences

The two GPUs come from different architecture generations and foundries. The RTX 6000 Ada is built on the AD102 chip using Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The RTX A4500 Mobile uses the GA104 chip with Ampere architecture, fabricated by Samsung on an 8 nm node. This process gap is central to the performance difference: the Ada chip packs 76,300 million transistors into a 609 mm² die, yielding a transistor density of 125.3 million per mm². The Ampere chip has 17,400 million transistors on a 392 mm² die, a density of just 44.4 million per mm². The Ada part crams over four times the transistors into about 1.5 times the die area.

Core counts differ massively. The RTX 6000 Ada has 18,176 shading units, 568 texture mapping units, 192 ROPs, 142 RT cores, and 568 tensor cores. The A4500 Mobile has 5,888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The desktop card has roughly 3.1 times the shading units, 3.1 times the TMUs, exactly 2 times the ROPs, 3.1 times the RT cores, and 3.1 times the tensor cores.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical. The RTX 6000 Ada is a dual-slot card with a 16-pin power connector and a suggested 700 W power supply, while the A4500 Mobile has no power connectors listed and is portable-device dependent. Display outputs also differ: the RTX 6000 Ada provides 4x DisplayPort 1.4a, while the mobile part's outputs are listed as portable device dependent. The RTX 6000 Ada is a fixed workstation component, whereas the A4500 Mobile is destined for laptops.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the first and more moderate of the two wins for the RTX 6000 Ada. Its score of 311,629 beats the A4500 Mobile's 105,307 by 195.9%. In practical terms, the desktop card delivers roughly three times the OpenCL compute throughput. This matters for rendering, simulation, and any OpenCL-accelerated professional workload. The mobile card's score is not trivial, it is in line with desktop parts like the Quadro GP100 (4.2% behind the A4500 Mobile), but it is nowhere near the Ada class.

The Geekbench Vulkan result shows an even larger gap. The RTX 6000 Ada scores 262,845, while the A4500 Mobile manages 76,960, a delta of 241.5%. The Vulkan advantage is more than 3.4 times. This suggests the Ada architecture's improvements are not just raw core count but also efficiency and driver optimization under Vulkan. The RTX 6000 Ada's nearest rivals in the database, the L40 and L40S, confirm this is a top-tier compute part. The A4500 Mobile's nearest rivals, including the AMD Radeon PRO W7600 (4.6% behind) and the Quadro GP100 (4.2% behind), show it competes with older or lower-tier hardware.

Across both tests, the RTX 6000 Ada records 2 wins and 0 losses. The A4500 Mobile records 0 wins and 2 losses. The average benchmark scores tell the same story: 287,237 for the Ada card versus 91,134 for the mobile card. That is a 3.15x difference in aggregate performance. No benchmark in the database favors the mobile part.

The Verdict

The data splits this comparison into two distinct use cases. For a fixed workstation with power and space available, the RTX 6000 Ada Generation is the overwhelming choice. It wins both recorded benchmarks, delivers 3.15x the average benchmark score of the mobile part, and sits in the 99th percentile of all GPUs. Its nearest rivals are the L40 and L40S, which are themselves top-tier compute accelerators. The 48 GB memory capacity, 960.0 GB/s bandwidth, and 91.06 TFLOPS FP32 make it suitable for large datasets and heavy compute. Its 300 W TDP and dual-slot cooler are acceptable in a desktop chassis. The launch MSRP is 6,799 USD.

For a laptop or any portable workstation, the RTX A4500 Mobile is the only option in this pair. It has a 140 W TDP, no external power connectors, and portable-device-dependent display outputs. Its 93rd percentile standing is decent for a mobile part, and its 16 GB memory with 512.0 GB/s bandwidth can handle moderate professional workloads. But its 17.66 TFLOPS FP32 and 5,888 shading units place it in a much lower performance tier. The nearest rivals for the A4500 Mobile, the desktop RTX A4500 and AMD Instinct MI60, are not modern top-end parts.

Do not buy the RTX A4500 Mobile expecting desktop Ada performance. The 195.9% OpenCL gap and 241.5% Vulkan gap are not close. If the workload is fixed and power is available, the RTX 6000 Ada is the only rational pick from these two. If mobility is mandatory, the A4500 Mobile is serviceable but its performance ceiling is roughly one third of the Ada card. The data does not support any other conclusion.
