NVIDIA RTX PRO 4500 Blackwell vs NVIDIA T1000 Comparison

Where Each One Wins

The benchmark data splits these two workstation GPUs into entirely different performance classes. The NVIDIA RTX PRO 4500 Blackwell takes the only direct head-to-head measurement recorded in the database, dominating the NVIDIA T1000 in Vulkan compute. The delta is enormous: the RTX PRO 4500 scores 221768 in Geekbench Vulkan, while the T1000 manages 34874. That is a 84.3% gap, meaning the RTX PRO 4500 delivers over six times the raw throughput in that workload.

The T1000 does not win a single recorded benchmark comparison. Its average benchmark score of 36289 places it in the 80th percentile of all GPUs, while the RTX PRO 4500 sits at 31532 average with a 76th percentile ranking. Interestingly, the percentile rankings do not align with raw performance: the T1000's lower absolute scores still land it higher relative to the wider GPU population, likely because the RTX PRO 4500 is compared against a more demanding modern benchmark suite that includes DirectX 12 and compute-heavy tests.

The RTX PRO 4500's Passmark results show where its strengths concentrate. The G3D score of 33360 and GPU compute score of 19255 indicate a card built for sustained rendering and compute workloads. The T1000 has no Passmark entries in the database, so its profile rests entirely on OpenCL and Vulkan results. The OpenCL score of 37704 for the T1000 is its best recorded figure, suggesting it remains capable in general-purpose compute despite its age. However, the RTX PRO 4500's Vulkan result alone dwarfs both T1000 scores combined.

For use-case planning, the T1000 suits legacy workstation environments where the total power envelope is constrained. Its 50 W TDP and single-slot design allow deployment in dense chassis. The RTX PRO 4500, with a 200 W TDP and dual-slot footprint, targets high-end visualization, AI inference, and large dataset handling. The 32 GB memory capacity versus 4 GB makes the RTX PRO 4500 the only viable option for models or scenes that exceed the T1000's frame buffer.

Architecture Differences

The two cards come from different architectural eras. The T1000 uses the Turing architecture on the TU117 chip, built on a 12 nm TSMC process. The RTX PRO 4500 Blackwell uses the GB203 chip on a 5 nm TSMC node. The process shrink allows the RTX PRO 4500 to pack 45,600 million transistors into a 378 mm² die, while the T1000 fits 4,700 million into 200 mm². Transistor density tells the story: 120.6 million per square millimeter for Blackwell versus 23.5 million for Turing.

The memory subsystems are generations apart. The T1000 uses 4 GB of GDDR6 on a 128 bit bus, yielding 160.0 GB/s of bandwidth. The RTX PRO 4500 uses 32 GB of GDDR7 on a 256 bit bus, delivering 896.0 GB/s. That is a 5.6x bandwidth advantage, which directly impacts texture streaming, large buffer operations, and multi-display output.

Compute resources differ by an order of magnitude. The T1000 has 896 shading units, 56 texture mapping units, and 32 ROPs. The RTX PRO 4500 has 10496 shading units, 328 TMUs, and 112 ROPs. The RTX PRO 4500 also includes 82 ray tracing cores and 328 tensor cores, while the T1000 has none of either. This makes the RTX PRO 4500 a fully featured accelerator for ray-traced rendering and tensor-based workloads, while the T1000 is limited to conventional rasterization and compute.

Clock behavior also differs. The T1000 runs at a 1065 MHz base and 1395 MHz boost. The RTX PRO 4500 runs at 1635 MHz base and 2407 MHz boost. Despite the higher clocks, the RTX PRO 4500 maintains a 200 W TDP, which is high but reasonable given the transistor count. The T1000 draws only 50 W and requires no external power connector, while the RTX PRO 4500 needs a single 16 pin connector and a 550 W suggested power supply.

The interface and output capabilities reflect their release timelines. The T1000 uses PCIe 3.0 x16 and outputs 4x mini-DisplayPort 1.4a. The RTX PRO 4500 uses PCIe 5.0 x16 and outputs 4x DisplayPort 2.1b. The newer card also supports DirectX 12 Ultimate (12_2), whereas the T1000 stops at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Physical dimensions reinforce the positioning. The T1000 is 156 mm long, 69 mm tall, and single-slot. The RTX PRO 4500 is 267 mm long, 111 mm tall, and 40 mm wide, occupying two slots. The T1000's compact size makes it suitable for small form factor workstations, while the RTX PRO 4500 requires a full tower or rack chassis with adequate airflow.

Head-to-Head Benchmarks

The database contains only one shared benchmark between the two cards: Geekbench Vulkan. The RTX PRO 4500 scores 221768, and the T1000 scores 34874. The delta percentage is -84.3, meaning the T1000 trails by that margin. This is not a close contest. The RTX PRO 4500's Vulkan result is approximately 6.36x higher, which aligns with the massive differences in shading units, memory bandwidth, and architecture generation.

Looking at the RTX PRO 4500's broader benchmark profile, its Passmark G3D score of 33360 places it near the NVIDIA TITAN RTX, which has an average score of 31676. The delta is -0.5%, meaning the RTX PRO 4500 is effectively tied with that older flagship. Against the Intel Arc Pro A30M, the RTX PRO 4500 is 1.1% behind in average score, while it leads the NVIDIA GRID M60-1Q by 1% and the Quadro M5000 by 1%. These are tight margins, suggesting the RTX PRO 4500 sits in a dense performance cluster for its average benchmark score.

The T1000's nearest rivals show a different competitive landscape. Its average score of 36289 is just 0.7% below the AMD Radeon RX 5300M and the NVIDIA GeForce GTX TITAN X. It leads the AMD Radeon Pro Duo by 1.2% and the NVIDIA Quadro GV100 by 2.2%. The T1000's percentile ranking of 80 reflects that its modest absolute performance still exceeds a majority of all recorded GPUs, partly because the database includes many older and low-end parts.

The Passmark DirectX tests for the RTX PRO 4500 show varied results. DirectX 9 scores 397, DirectX 10 scores 204, DirectX 11 scores 320, and DirectX 12 scores 119. The low DirectX 12 number relative to the others is notable, as it suggests the card's drivers or hardware may favor older API paths in that specific suite, or the test itself is not representative of the card's peak capability. The G2D score of 1336 indicates strong 2D acceleration, which matters for multi-monitor productivity work.

The RTX PRO 4500's 3DMark Steel Nomad DX12 score of 7025 provides a modern gaming-oriented metric, but the T1000 has no comparable entry. This asymmetry in available benchmarks means cross-card comparisons rely heavily on the single Vulkan result and the average score figures.
