NVIDIA GeForce GTX 750 vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

Head-to-Head Benchmarks

The recorded benchmark data for these two cards is sparse and does not overlap on a single shared test. The GeForce GTX 750 has scores in three compute-oriented APIs: Geekbench Metal at 4274, Geekbench OpenCL at 9315, and Geekbench Vulkan at 8078. Its average benchmark score across those results is 7222. The RTX PRO 6000 Blackwell Server has only one recorded result, a 3DMark Steel Nomad DX12 score of 5996, which is also its average score. Because the test suites differ completely, there is no direct head-to-head comparison possible from the database. The GTX 750 sits at the 40th percentile among all GPUs, while the RTX PRO 6000 sits at the 34th percentile, but this percentile rank is based on different workloads and should not be read as a performance ordering.

The nearest rivals in the database provide context for each card. The GTX 750's average of 7222 places it within a tight cluster: the AMD Radeon Vega 8 Mobile scores 7203, a delta of 0.3 percent, the NVIDIA GeForce GTX 560 SE scores 7171 (0.7 percent behind), the Intel Iris Pro Graphics P580 scores 7170 (0.7 percent behind), and the NVIDIA GeForce GTX 970 scores 7157 (0.9 percent behind). This indicates the GTX 750, despite its small 1024 MB frame buffer, performs on par with iGPUs and older discrete parts in these OpenCL and Vulkan tests. The RTX PRO 6000 Blackwell Server, meanwhile, has nearest rivals that are dramatically weaker in hardware class: the NVIDIA GeForce GTX 770M scores 6000 (0.1 percent ahead), the AMD Radeon RX 6400 scores 6001 (0.1 percent ahead), the AMD FirePro W4100 scores 5987 (0.2 percent behind), and the NVIDIA Quadro K4000M scores 5986 (0.2 percent behind). A modern 96 GB server card scoring within 0.2 percent of a decade-old mobile GPU in one DX12 test is a striking result, but it is likely a reflection of the single workload and the comparison pool, not a statement about raw capability.

Architecture Differences

The architectural gap between the two GPUs is enormous, and the specification fields make that explicit. The GTX 750 uses the GM107 chip, built on a 28 nm process at TSMC, with 1,870 million transistors on a die of 148 mm², yielding a transistor density of 12.6M per mm². It belongs to the Maxwell architecture, GeForce 700 generation, and was released in 2014-02-02. The RTX PRO 6000 Blackwell Server uses the GB202 chip on a 5 nm process, also TSMC foundry, with 92,200 million transistors on a 750 mm² die, for a density of 122.9M per mm². It is Blackwell 2.0, from the Server Blackwell generation. The process shrink from 28 nm to 5 nm allowed a transistor count roughly 49 times higher on a die roughly 5 times larger, which is the core of the performance difference. The GTX 750 has 512 shading units, 32 TMUs, and 16 ROPs. The RTX PRO 6000 Blackwell Server has 24,064 shading units, 752 TMUs, 192 ROPs, 188 RT cores, and 752 tensor cores. Clock speeds differ as well: the GTX 750 runs a base of 1020 MHz and a boost of 1085 MHz, with memory at 1253 MHz, 5 Gbps effective. The RTX PRO 6000 Blackwell Server runs a base of 1590 MHz and a boost of 2617 MHz, with memory at 1750 MHz, 28 Gbps effective. The RTX PRO 6000 supports 126.0 TFLOPS FP32 and 126.0 TFLOPS FP16 with a 1:1 ratio, while the GTX 750 delivers 1,111.0 GFLOPS FP32 and has no listed FP16 capability. Pixel and texture rates follow the same pattern: 17.36 GPixel/s and 34.72 GTexel/s for the GTX 750, versus 502.5 GPixel/s and 1,968.0 GTexel/s for the RTX PRO 6000. Memory architecture is entirely different: the GTX 750 has 1024 MB of GDDR5 on a 128 bit bus with 80.19 GB/s bandwidth, while the RTX PRO 6000 Blackwell Server has 96 GB of GDDR7 on a 512 bit bus with 1.79 TB/s bandwidth. API support differs too: the GTX 750 lists DirectX 12 (11_0), while the RTX PRO 6000 lists DirectX 12 Ultimate (12_2); both support OpenGL 4.6 and Vulkan 1.4. Power and physical design are not comparable in scale: the GTX 750 is a 55 W single-slot card with no power connectors and a suggested PSU of 250 W, while the RTX PRO 6000 is a 600 W dual-slot card with one 16-pin connector and a suggested PSU of 1000 W. The bus interface moved from PCIe 3.0 x16 to PCIe 5.0 x16. Display outputs went from 2x DVI and 1x mini-HDMI 1.4a on the GTX 750 to 4x DisplayPort 2.1b on the RTX PRO 6000. The GTX 750 is end-of-life, with the GeForce 900 series as its successor; the RTX PRO 6000 is active, with Server Rubin as its successor.

The Verdict

The data presents two cards that occupy completely different tiers, and the only shared metrics are the ones where they do not actually meet in a single benchmark. The GTX 750 is a low-power, end-of-life desktop card with a 55 W TDP, 1024 MB of memory, and average scores in the 7000 range in OpenCL, Vulkan, and Metal tests. Its nearest rivals are integrated graphics and older discrete GPUs, which tells a builder that it belongs in legacy or low-demand systems. The RTX PRO 6000 Blackwell Server is an active, 600 W, 96 GB server card with 188 RT cores, 752 tensor cores, and 126.0 TFLOPS FP32. Its nearest rivals in the database are a GTX 770M, an RX 6400, a FirePro W4100, and a Quadro K4000M, all within 0.2 percent of its single recorded score. That does not mean the RTX PRO 6000 is weak; it means the database's single DX12 workload for this card does not represent its compute-heavy server role. Anyone selecting between these two for a new build should note that the GTX 750 is end-of-life and its successor is the GeForce 900 series. The RTX PRO 6000 is active, and its successor is Server Rubin. For a server workload with ray tracing, tensor operations, or large memory footprints, the RTX PRO 6000 Blackwell Server is the only one of the two with the required hardware. For a low-power legacy desktop, the GTX 750 is the only one that fits the 55 W envelope.

The launch MSRP of the GTX 750 is 119 USD; the RTX PRO 6000 has no launch MSRP listed.

Where Each One Wins

The GTX 750 wins in scenarios defined by low power and legacy compatibility. Its 55 W TDP and no power connectors mean it can run in systems with a 250 W suggested PSU, including older desktops without auxiliary GPU power. Its single-slot design and 145 mm length fit compact cases. Its average benchmark score of 7222 places it within 0.9 percent of the GeForce GTX 970 and just above the Radeon Vega 8 Mobile, so for OpenCL and Vulkan compute tasks in that class, it is competitive. The RTX PRO 6000 Blackwell Server wins in every scenario that demands modern server features. Its 96 GB GDDR7 memory on a 512 bit bus with 1.79 TB/s bandwidth is built for large datasets. Its 188 RT cores and 752 tensor cores enable hardware ray tracing and tensor operations, which the GTX 750 cannot do at all. Its 126.0 TFLOPS FP32 and 126.0 TFLOPS FP16 with 1:1 ratio give it a massive compute advantage over the GTX 750's 1,111.0 GFLOPS FP32. Its PCIe 5.0 x16 interface and 4x DisplayPort 2.1b outputs are current-generation standards. The 600 W TDP and 1000 W suggested PSU reflect a workstation or server power budget, not a desktop one. The GTX 750 is the pick for a low-power legacy machine, and the RTX PRO 6000 Blackwell Server is the pick for any workload that can use its memory, ray tracing, tensor cores, or raw FP32 throughput. There is no recorded workload where both cards ran the same test, so the database does not provide a single overlapping win for either card. The differentiation is entirely architectural.
