NVIDIA RTX A4500 Mobile vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the NVIDIA RTX PRO 5000 Blackwell in the two shared benchmark tests. In Geekbench OpenCL, the RTX PRO 5000 Blackwell scores 254,116 against 105,307 for the RTX A4500 Mobile, a 141.3% advantage. This is not a marginal gap; it represents more than double the raw compute throughput in an API that stresses general-purpose GPU workloads. The Vulkan results are even more lopsided: 282,631 versus 76,960, a 267.2% delta. That is nearly four times the score, indicating the Blackwell architecture handles modern graphics and compute APIs with far greater efficiency per clock.

Looking at the broader database context, the RTX PRO 5000 Blackwell sits at the 98th percentile among all GPUs, with an average benchmark score of 182,109. Its nearest rivals include the NVIDIA A100 SXM4 80 GB (average score 183,725, only 0.9% higher) and the RTX 5000 Ada Generation (184,664, 1.4% higher). The RTX A4500 Mobile, by contrast, lands at the 93rd percentile with an average score of 91,134. Its closest competitor is the desktop RTX A4500 (91,671, just 0.6% higher), meaning the mobile part essentially matches its desktop counterpart. The delta between the two products in the database is roughly 100% on average, which aligns with the head-to-head results.

The win tally is 2 for the RTX PRO 5000 Blackwell, 0 for the RTX A4500 Mobile. Every measurable benchmark in the comparison favors the newer, larger chip. The Vulkan gap is especially telling because Vulkan tends to scale well with raw shader counts and memory bandwidth, both of which are dramatically higher on the Blackwell part.

Architecture Differences

The foundation of this performance split lies in the silicon itself. The RTX PRO 5000 Blackwell uses the GB202 chip built on a 5 nm process at TSMC, packing 92,200 million transistors into a 750 mm² die. That yields a transistor density of 122.9 million per square millimeter. The RTX A4500 Mobile uses the GA104 chip on Samsung's 8 nm process, with 17,400 million transistors on a 392 mm² die, or 44.4 million per square millimeter. The Blackwell part is not just larger; it is denser by a factor of nearly three, which explains how it fits 14080 shading units, 440 TMUs, and 160 ROPs into the same power envelope class.

The memory subsystem tells a similar story. The RTX PRO 5000 Blackwell ships with 48 GB of GDDR7 on a 384-bit bus, delivering 1.34 TB/s of bandwidth. The RTX A4500 Mobile has 16 GB of GDDR6 on a 256-bit bus, capping at 512.0 GB/s. That is a 2.6x bandwidth advantage for the Blackwell card, which directly feeds its higher fill rates: 380.3 GPixel/s versus 144.0 GPixel/s, and 1,045.9 GTexel/s versus 276.0 GTexel/s. Ray tracing hardware also scales: 110 RT cores and 440 tensor cores on the Blackwell, versus 46 RT cores and 184 tensor cores on the Ampere part. FP32 compute is 66.94 TFLOPS versus 17.66 TFLOPS, a 3.8x gap that shows up in the OpenCL benchmark.

Clock speeds differ as well. The RTX PRO 5000 Blackwell runs at a base of 1740 MHz and boosts to 2377 MHz. The RTX A4500 Mobile starts at 930 MHz and boosts to 1500 MHz. Even accounting for the mobile part's lower thermal budget, the raw clock advantage compounds with the core count advantage. The process node difference (5 nm versus 8 nm) and foundry choice (TSMC versus Samsung) are the root enablers of those clock and density gains.

FAQ

The Verdict

The data points to a clear hierarchy. The RTX PRO 5000 Blackwell is in the top 2% of all GPUs (98th percentile), while the RTX A4500 Mobile sits at the 93rd percentile. The average benchmark score gap is roughly 100% (182,109 versus 91,134), and in the two shared tests, the Blackwell part wins by 141.3% and 267.2%. For any workload that relies on FP32 compute, ray tracing, or memory bandwidth, the RTX PRO 5000 Blackwell is the superior choice.

The RTX A4500 Mobile is not a weak product in absolute terms. It outperforms the Quadro GP100 by 4.2% and the Radeon PRO W7600 by 4.6%, and it nearly matches the desktop RTX A4500. But it is end-of-life, built on an older 8 nm Samsung process, and constrained by a 140 W mobile power budget. Its 16 GB memory capacity and 512.0 GB/s bandwidth are adequate for mid-range professional workloads, but they are not in the same league as the Blackwell part's 48 GB and 1.34 TB/s.

The choice is straightforward if you are selecting between these two for a new system. The RTX PRO 5000 Blackwell is active, current, and faster in every measured category. The RTX A4500 Mobile is a legacy part that should only be considered if you already have a system designed around it or need a low-power mobile solution where the 300 W desktop card is not an option.

Where Each One Wins

NVIDIA RTX PRO 5000 Blackwell wins in:

• Raw compute throughput: 66.94 TFLOPS FP32 versus 17.66 TFLOPS, a 3.8x lead that shows up in OpenCL (141.3% higher score).
• Modern API performance: Vulkan score is 267.2% higher, indicating better driver optimization and hardware support for current graphics workloads.
• Memory capacity and bandwidth: 48 GB GDDR7 at 1.34 TB/s versus 16 GB GDDR6 at 512.0 GB/s. This matters for large dataset processing, AI training, and high-resolution rendering.

• Longevity: Active production status and a 2025 release date mean it will receive support for years to come.
• Display flexibility: 4x DisplayPort 2.1b outputs versus portable-device-dependent outputs on the mobile part.

NVIDIA RTX A4500 Mobile wins in:

• Power efficiency per unit of work: At 140 W TDP versus 300 W, it delivers 17.66 TFLOPS with less than half the power draw. For battery-powered or thermally constrained systems, this is the only practical option.
• Physical footprint: No slot width, no power connectors, and no specified dimensions. It is designed to fit inside a laptop chassis, while the RTX PRO 5000 Blackwell requires a dual-slot, 267 mm long, 111 mm tall, 40 mm wide card with a 16-pin connector and a 700 W suggested PSU.
• Legacy compatibility: Its predecessor is Quadro Turing-M, and its successor is Ada-MW, meaning it belongs to a mature product line with established driver support for older professional applications.
• Cost of entry: There is no launch MSRP recorded for the RTX A4500 Mobile, but the RTX PRO 5000 Blackwell carries a 5,099 USD launch MSRP, which is a significant investment. The mobile part was likely more accessible at its launch, though that data is not in the database.

The verdict is not about which card is "better" in a vacuum. It is about matching the hardware to the environment. Desktop workstations with ample power and cooling should use the RTX PRO 5000 Blackwell. Mobile workstations that need professional-grade compute on the go have no alternative but the RTX A4500 Mobile, accepting its lower performance as the trade-off for portability.
