AMD Radeon Pro 575X vs NVIDIA T1000 8 GB Comparison

The Verdict

The benchmark database places the AMD Radeon Pro 575X and the NVIDIA T1000 8 GB in adjacent performance percentiles, but with different strengths. The AMD part sits at the 82nd percentile of all GPUs with an average benchmark score of 39,116, while the NVIDIA T1000 sits at the 79th percentile with an average score of 34,561. That is a roughly 13.2% gap in average score, but only one shared benchmark test is recorded in the database, so the comparison is narrower than the averages suggest.

The Radeon Pro 575X wins the only direct head-to-head test, the Geekbench Vulkan workload, scoring 37,919 against 34,561 for the T1000, a 9.7% advantage. For users who prioritize raw compute throughput in Vulkan or OpenCL-style workloads, the AMD card is the clear choice from the recorded data. Its FP32 output of 4.489 TFLOPS is nearly double the T1000's 2.500 TFLOPS, and its texture rate of 140.3 GTexel/s is substantially higher than the T1000's 78.12 GTexel/s.

However, the T1000 offers 8 GB of GDDR6 memory versus 4 GB of GDDR5 on the AMD card, and it does so at a 50 W TDP versus 150 W for the Radeon. The T1000 also supports DirectX 12_1 and Vulkan 1.4, while the Radeon Pro 575X is limited to DirectX 12_0 and Vulkan 1.3. The NVIDIA card is a single-slot, low-power solution with four mini-DisplayPort 1.4a outputs, whereas the AMD card is an integrated GPU (IGP) with portable-device-dependent outputs, meaning it is tied to a specific Mac chassis.

The verdict from the data: the Radeon Pro 575X is the stronger compute performer for Vulkan-based tasks and any workload that leans on FP32 or texturing throughput. The T1000 8 GB is the better choice for systems where power draw, memory capacity, or modern API feature levels matter more than raw compute scores. The T1000's nearest rivals include the NVIDIA A2 (average score 34,690, T1000 trails by 0.4%) and the RTX A1000 (average score 34,207, T1000 leads by 1%), which places it in a crowded field of low-power workstation cards. The Radeon's nearest rivals are closer in score: the Radeon Pro 580X is 1.1% behind it, and the Radeon Pro 575 is 1.1% ahead, indicating that the 575X sits right at the edge of its performance tier.

Where Each One Wins

The AMD Radeon Pro 575X wins on pure compute metrics. Its FP32 throughput of 4.489 TFLOPS is 79.6% higher than the T1000's 2.500 TFLOPS. Its pixel rate of 35.07 GPixel/s is lower than the T1000's 44.64 GPixel/s, but its texture rate of 140.3 GTexel/s is 79.6% higher than the T1000's 78.12 GTexel/s. The Radeon also has a wider memory bus at 256 bit versus 128 bit, delivering 217.0 GB/s of bandwidth versus 160.0 GB/s for the T1000. In the Geekbench Vulkan test, the Radeon leads by 9.7%.

The NVIDIA T1000 wins on efficiency and memory capacity. It draws 50 W compared to 150 W for the Radeon, which is a 67% reduction in power consumption. It offers 8 GB of GDDR6 memory, double the AMD card's 4 GB of GDDR5. The T1000 also has a higher pixel rate (44.64 GPixel/s versus 35.07 GPixel/s), which suggests it can fill framebuffers faster, and it supports FP16 at 5.000 TFLOPS with a 2:1 ratio, whereas the Radeon's FP16 is identical to its FP32 at 4.489 TFLOPS (1:1). The T1000's base clock of 1065 MHz and boost clock of 1395 MHz are not directly comparable to the Radeon's unspecified clock, but the memory clock of 1250 MHz (10 Gbps effective) is faster per pin than the Radeon's 1695 MHz (6.8 Gbps effective).

For users who need to run larger datasets or multiple displays, the T1000's 8 GB frame buffer and four mini-DisplayPort outputs are decisive advantages. For users who need maximum shader throughput in a Vulkan or OpenCL environment, the Radeon Pro 575X is the stronger part, provided the host system can supply 150 W and accept an integrated GPU.

Architecture Differences

The AMD Radeon Pro 575X is built on the Ellesmere chip using GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It contains 5,700 million transistors on a 232 mm² die, giving a transistor density of 24.6 million per mm². The chip has 2,048 shading units, 128 texture mapping units, and 32 ROPs. Its memory subsystem uses 4 GB of GDDR5 on a 256 bit bus, achieving 217.0 GB/s of bandwidth. The memory clock is listed at 1695 MHz, or 6.8 Gbps effective. The card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. It is an integrated GPU (IGP) with no power connectors and portable-device-dependent display outputs. Its production status is end-of-life, and it was released in March 2019.

The NVIDIA T1000 8 GB is built on the TU117 chip using Turing architecture, manufactured on a 12 nm process at TSMC. It contains 4,700 million transistors on a 200 mm² die, giving a transistor density of 23.5 million per mm². The chip has 896 shading units, 56 texture mapping units, and 32 ROPs. Its memory subsystem uses 8 GB of GDDR6 on a 128 bit bus, achieving 160.0 GB/s of bandwidth. The memory clock is listed at 1250 MHz, or 10 Gbps effective. The GPU has a base clock of 1065 MHz and a boost clock of 1395 MHz. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. It is a single-slot card with four mini-DisplayPort 1.4a outputs and no power connectors. Its production status is end-of-life, and it was released in May 2021, succeeding the Quadro Volta line and preceding Workstation Ampere.

The architectural differences are significant. The AMD chip has more than twice the shading units (2,048 versus 896) and more than twice the TMUs (128 versus 56), but the NVIDIA chip has a smaller process node (12 nm versus 14 nm) and a higher pixel rate (44.64 GPixel/s versus 35.07 GPixel/s). The AMD part has a wider memory bus (256 bit versus 128 bit) and higher bandwidth (217.0 GB/s versus 160.0 GB/s), but the NVIDIA part uses newer GDDR6 memory and supports a higher DirectX feature level (12_1 versus 12_0). The T1000 also supports FP16 at twice the rate of FP32 (5.000 TFLOPS versus 2.500 TFLOPS), while the Radeon's FP16 is at a 1:1 ratio with FP32 (4.489 TFLOPS). Neither part has dedicated ray tracing cores or tensor cores, according to the database.

Head-to-Head Benchmarks

The database records a single shared benchmark between the two cards: Geekbench Vulkan. The AMD Radeon Pro 575X scores 37,919, and the NVIDIA T1000 scores 34,561. The AMD card wins by 9.7%. This is a meaningful margin, but it is worth placing in context. The Radeon's nearest rivals in the database include the Radeon Pro 580X (average score 38,706, 1.1% behind the 575X) and the Radeon Pro 575 (average score 39,555, 1.1% ahead). The T1000's nearest rivals include the NVIDIA A2 (average score 34,690, T1000 trails by 0.4%) and the NVIDIA TITAN V (average score 34,355, T1000 leads by 0.6%).

The Vulkan result aligns with the raw specification differences. The Radeon has 2,048 shading units versus 896 for the T1000, and its FP32 throughput of 4.489 TFLOPS is nearly double the T1000's 2.500 TFLOPS. The Radeon also has 217.0 GB/s of memory bandwidth versus 160.0 GB/s for the T1000, which helps in memory-intensive Vulkan workloads. The T1000's higher pixel rate (44.64 GPixel/s versus 35.07 GPixel/s) does not appear to compensate in this particular test, as the Radeon still wins by nearly 10%.

The other benchmark scores in the database are not directly comparable because they were not run on both cards. The Radeon Pro 575X has Geekbench Metal and OpenCL scores of 44,655 and 34,773, respectively, in addition to its Vulkan score. The T1000 only has a Vulkan score recorded. The Radeon's average benchmark score across all its tests is 39,116, while the T1000's average is 34,561, a difference of 13.2%. This aggregate gap is larger than the Vulkan-only gap, suggesting the Radeon's Metal and OpenCL results are stronger relative to its Vulkan result.

The wins tally in the head-to-head section is 1 win for the AMD Radeon Pro 575X and 0 for the NVIDIA T1000. That is based solely on the Vulkan test. The data does not include a Metal or OpenCL comparison between the two cards, so no conclusion can be drawn about those APIs. The T1000's advantages are structural: 8 GB of memory, 50 W power draw, single-slot form factor, and four display outputs. The Radeon's advantages are computational: more shaders, more texture units, higher FP32, and higher memory bandwidth. In a Vulkan-only benchmark, the Radeon wins. In a real workstation environment, the choice depends on whether compute throughput or memory capacity and power efficiency are the priority.
