NVIDIA RTX PRO 4500 Blackwell vs NVIDIA T600 Mobile Comparison

The NVIDIA T600 Mobile and NVIDIA RTX PRO 4500 Blackwell are separated by more than a generation of GPU architecture, and the data reflects that chasm. In the only directly comparable benchmark, the RTX PRO 4500 Blackwell delivers a Vulkan score of 221,768 against the T600 Mobile’s 30,211, a delta of -86.4% from the perspective of the older card. The RTX PRO 4500 Blackwell is the decisive winner in raw compute, but the T600 Mobile holds its own as a low-power, end-of-life mobile part with a distinct niche.

Head-to-Head Benchmarks

The single head-to-head result is the Geekbench Vulkan test, and it is not close. The RTX PRO 4500 Blackwell scores 221,768, while the T600 Mobile scores 30,211. That means the RTX PRO 4500 Blackwell is roughly 7.3 times faster in Vulkan compute, a gap that reflects the massive differences in every hardware category. The deltaPct of -86.4% indicates the T600 Mobile’s score is 86.4% lower than the winner’s, which is a stark verdict for anyone considering these two for the same workload.

Beyond that single test, the broader benchmark averages tell a similar story. The T600 Mobile’s average benchmark score is 32,849, while the RTX PRO 4500 Blackwell’s is 31,532. This is counterintuitive at first glance, but it is explained by the benchmark sets: the T600 Mobile’s average is drawn only from two Geekbench tests (OpenCL and Vulkan), both of which are compute-oriented and score well for its class. The RTX PRO 4500 Blackwell’s average includes a wider mix, including Passmark DX9, DX10, DX11, DX12, and G2D tests, which pull its average down despite a Passmark G3D score of 33,360 and a GPU compute score of 19,255.

In isolation, the RTX PRO 4500 Blackwell’s Vulkan score of 221,768 is more than 7 times the T600 Mobile’s 30,211. Its 3DMark Steel Nomad DX12 score of 7,025 is also a strong indicator of modern gaming and DXR-class performance, a test the T600 Mobile does not even have listed. The T600 Mobile’s best single result is its Geekbench OpenCL score of 35,486, which is respectable for a 40 W mobile part but still far below the RTX PRO 4500 Blackwell’s Vulkan result.

Where Each One Wins

The RTX PRO 4500 Blackwell wins every head-to-head comparison and every meaningful performance metric in the pack. It is the clear choice for any workload that demands high throughput: the 50.53 TFLOPS FP32 performance, 896.0 GB/s memory bandwidth, and 32 GB of GDDR7 memory are all orders of magnitude beyond the T600 Mobile’s capabilities. The 3DMark Steel Nomad score of 7,025 and Passmark G3D score of 33,360 confirm it is built for heavy 3D rendering, simulation, and AI-adjacent tasks (given the 328 tensor cores and 82 RT cores).

The T600 Mobile, by contrast, wins in efficiency and portability. With a 40 W TDP and IGP slot width, it requires no power connectors and is designed for thin, portable devices. Its 4 GB GDDR6 memory and 192.0 GB/s bandwidth are modest, but its Geekbench OpenCL score of 35,486 shows it can handle light compute tasks reasonably well for its class. The T600 Mobile is end-of-life and was released in April 2021, while the RTX PRO 4500 Blackwell is active and released in March 2025. For legacy mobile workstations or low-power embedded systems, the T600 Mobile’s 12 nm Turing architecture remains serviceable, but it cannot compete on any performance axis.

The RTX PRO 4500 Blackwell also has a higher percentile ranking among all GPUs (76th) compared to the T600 Mobile’s 77th percentile. This near-parity in percentile is misleading, as it reflects the entire GPU population, including many older and weaker cards. The RTX PRO 4500 Blackwell’s nearest rivals are the NVIDIA TITAN RTX (average score 31,676, delta -0.5%), NVIDIA GRID M60-1Q (31,220, delta 1%), and NVIDIA Quadro M5000 (31,206, delta 1%). The T600 Mobile’s nearest rivals include the NVIDIA P104-100 (32,982, delta -0.4%) and AMD Radeon RX 590 GME (32,601, delta 0.8%). Both cards sit in similar competitive brackets, but the RTX PRO 4500 Blackwell does so with far more modern hardware.

Architecture Differences

The T600 Mobile is built on the TU117 chip using Turing architecture and a 12 nm TSMC process. It has 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5 million per mm². The RTX PRO 4500 Blackwell uses the GB203 chip on Blackwell 2.0 architecture and a 5 nm TSMC process, packing 45,600 million transistors into a 378 mm² die—a density of 120.6 million per mm². That is a 5.1 times increase in transistor count and a 5.1 times increase in density, all while the die is only 1.89 times larger.

Core counts are equally divergent. The T600 Mobile has 896 shading units, 56 texture mapping units, and 32 ROPs. The RTX PRO 4500 Blackwell has 10,496 shading units, 328 TMUs, and 112 ROPs—11.7 times more shaders, 5.9 times more TMUs, and 3.5 times more ROPs. The RTX PRO 4500 Blackwell also includes 82 RT cores and 328 tensor cores, while the T600 Mobile has none listed. This is a fundamental architectural split: Turing’s TU117 lacks dedicated ray tracing and tensor hardware, while Blackwell 2.0’s GB203 is fully equipped for both.

Memory differences are stark. The T600 Mobile uses 4 GB of GDDR6 on a 128-bit bus, with memory clocked at 1500 MHz (12 Gbps effective) and bandwidth of 192.0 GB/s. The RTX PRO 4500 Blackwell uses 32 GB of GDDR7 on a 256-bit bus, with memory at 1750 MHz (28 Gbps effective) and bandwidth of 896.0 GB/s. That is 8 times the capacity and 4.7 times the bandwidth. Clock speeds also favor the newer card: base 1635 MHz versus 780 MHz, boost 2407 MHz versus 1410 MHz.

The RTX PRO 4500 Blackwell supports DirectX 12 Ultimate (12_2), while the T600 Mobile supports only DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX PRO 4500 Blackwell also has a PCIe 5.0 x16 interface versus the T600 Mobile’s PCIe 3.0 x16. Power delivery reflects the performance gap: the RTX PRO 4500 Blackwell is a dual-slot card with a 200 W TDP and a single 16-pin power connector, requiring a 550 W suggested PSU. The T600 Mobile is an IGP with a 40 W TDP and no power connectors.

The Verdict

The data is unambiguous: the RTX PRO 4500 Blackwell is the superior GPU for any performance-critical task. Its 50.53 TFLOPS FP32 output, 896.0 GB/s bandwidth, and 32 GB of GDDR7 memory make it a workstation-class part suited for large datasets, complex renders, and modern DX12 Ultimate workloads. The 3DMark Steel Nomad score of 7,025 and Vulkan score of 221,768 confirm it can handle the most demanding applications. The 82 RT cores and 328 tensor cores provide hardware acceleration that the T600 Mobile simply lacks.

The T600 Mobile is a different product for a different purpose. With a 40 W TDP, IGP form factor, and no power connectors, it fits into ultra-portable laptops where battery life and thermal limits dominate. Its 4 GB GDDR6 memory and 2.527 TFLOPS FP32 are adequate for light CAD, basic video playback, and modest compute. Its Geekbench OpenCL score of 35,486 is respectable for its class, but it trails the RTX PRO 4500 Blackwell by an order of magnitude in every modern benchmark.

For buyers, the choice is straightforward. If the workload involves heavy 3D rendering, AI inference, or high-resolution video editing, the RTX PRO 4500 Blackwell is the only rational selection—it outscores the T600 Mobile in Vulkan by 191,557 points and offers nearly 20 times the FP32 throughput. If the requirement is a low-power, fanless mobile GPU for legacy applications, the T600 Mobile remains a functional option, but its end-of-life status and lack of RT/tensor hardware limit its future utility. The RTX PRO 4500 Blackwell is the verdict for anyone who needs performance; the T600 Mobile is the verdict for anyone who needs minimal power draw in a portable chassis.
