NVIDIA GeForce GTX 750 vs NVIDIA Quadro K1200 Comparison

The Verdict

The database comparison shows a narrow but consistent edge for the NVIDIA GeForce GTX 750 in raw compute benchmarks. In the two shared tests, the GTX 750 wins both: it posts a Geekbench OpenCL score of 9315 versus 8831 for the Quadro K1200, a delta of 5.2%, and a Geekbench Vulkan score of 8078 versus 7698, a delta of 4.7%. If the decision rests purely on measured performance, the GTX 750 is the faster card.

However, the intended use case changes the calculus. The Quadro K1200 is a workstation-oriented board with 4 GB of GDDR5 memory, four mini-DisplayPort outputs, and a 45 W TDP. The GTX 750 is a consumer card with 1024 MB of memory, dual DVI plus mini-HDMI, and a 55 W TDP. Professionals driving multiple high-resolution displays or working with larger datasets should favor the Quadro for its memory capacity and display configuration. Gamers or users prioritizing compute throughput should pick the GTX 750. The Quadro also carries a lower power draw, making it the choice for constrained or multi-GPU systems where 45 W per card matters. The GTX 750, meanwhile, has a higher base clock (1020 MHz versus 954 MHz) and boost clock (1085 MHz versus 1033 MHz), which partly explains its benchmark advantage.

The average benchmark scores tell a different story than the head-to-head results. The Quadro K1200 has an average score of 8265 across its recorded tests, while the GTX 750 averages 7222. That discrepancy stems from the GTX 750 including a Geekbench Metal score of 4274, which drags down its average. In the two tests where both cards were measured under identical conditions, the GTX 750 leads. The percentile rankings also favor the Quadro: it sits at the 43rd percentile of all GPUs, while the GTX 750 sits at the 40th. So the Quadro is the more consistent overall performer in the broader database, even though it loses the direct comparisons.

Architecture Differences

Both cards are built on the same NVIDIA Maxwell architecture using the GM107 chip, fabricated by TSMC on a 28 nm process. They share the identical transistor count of 1,870 million and die size of 148 mm², yielding the same transistor density of 12.6 million transistors per square millimeter. The underlying compute core is also the same: 512 shading units, 32 texture mapping units, and 16 raster output units.

The architectural split lies in their intended deployment. The Quadro K1200 belongs to the Quadro Kepler generation (Kx200) according to the database, despite being a Maxwell chip. Its predecessor is listed as Quadro Fermi, and its successor as Quadro Maxwell. The GTX 750 belongs to the GeForce 700 generation, with a predecessor of GeForce 600 and a successor of GeForce 900.

The display output architecture diverges significantly. The Quadro K1200 is clearly designed for multi-monitor professional setups with four mini-DisplayPort 1.2 connections. The GTX 750 uses a consumer configuration of two DVI ports plus one mini-HDMI 1.4a. Both support DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4, so API-level features are identical. Neither card has ray tracing cores or tensor cores.

The bus interface differs as well: the Quadro K1200 uses PCIe 2.0 x16, while the GTX 750 uses PCIe 3.0 x16. This does not appear in the benchmark results, but it reflects the workstation card's focus on stability over peak interconnect speed. Both cards are single-slot designs and require no external power connectors.

Specification Differences

The two cards share many core specifications, but the differences define their roles. Clock speeds favor the GTX 750, with a base of 1020 MHz and boost of 1085 MHz, versus 954 MHz base and 1033 MHz boost for the Quadro K1200. This translates directly into higher pixel and texture throughput: the GTX 750 achieves 17.36 GPixel/s and 34.72 GTexel/s, while the Quadro K1200 manages 16.53 GPixel/s and 33.06 GTexel/s. Floating-point performance follows the same pattern, with the GTX 750 delivering 1,111.0 GFLOPS FP32 against 1,057.8 GFLOPS for the Quadro.

Memory capacity is the biggest differentiator. The Quadro K1200 has 4 GB of GDDR5, four times the 1024 MB of the GTX 750. Memory type, bus width, and bandwidth are identical: GDDR5, 128-bit, and 80.19 GB/s. The effective memory clock is also the same at 5 Gbps.

Power and physical characteristics differ. The Quadro K1200 draws 45 W with a suggested PSU of 200 W, while the GTX 750 draws 55 W with a suggested PSU of 250 W. The Quadro is longer at 160 mm (6.3 inches) and has a listed height of 69 mm (2.7 inches). The GTX 750 is 145 mm (5.7 inches) with no height listed. Both are single-slot and require no power connectors.

The GTX 750 has a launch MSRP of 119 USD. The Quadro K1200 has no recorded launch MSRP in the database.

Head-to-Head Benchmarks

The direct comparison contains two tests, and the GTX 750 wins both. In Geekbench OpenCL, the GTX 750 scores 9315 against the Quadro K1200's 8831, a 5.2% advantage. The delta indicates the Quadro trails by that margin. This result aligns with the clock speed difference: the GTX 750's higher base and boost frequencies give it a measurable edge in compute workloads that scale with raw throughput.

In Geekbench Vulkan, the GTX 750 scores 8078 against 7698, a 4.7% margin. The Vulkan gap is slightly smaller than the OpenCL gap, suggesting the Quadro's architecture handles the newer API somewhat more efficiently relative to its clocks. Still, the GTX 750 maintains its lead in both API tests.

The broader benchmark picture complicates the head-to-head story. The Quadro K1200's average score of 8265 places it among rivals like the AMD Radeon R9 M375X (8325, 0.7% ahead of the Quadro), the NVIDIA GeForce GTX 980 (8167, 1.2% behind), the NVIDIA GeForce GTX 950M (8135, 1.6% behind), and the AMD Radeon R9 M360 (8129, 1.7% behind). The Quadro sits in the middle of that group, within a 2.4% spread.

The GTX 750's average of 7222 places it among the AMD Radeon Vega 8 Mobile (7203, 0.3% ahead), the NVIDIA GeForce GTX 560 SE (7171, 0.7% behind), the Intel Iris Pro Graphics P580 (7170, 0.7% behind), and the NVIDIA GeForce GTX 970 (7157, 0.9% behind). The GTX 750 is effectively tied with this group, all within a 0.9% spread.

The interesting wrinkle is the GTX 750's Metal score of 4274, which is not recorded for the Quadro K1200. That single low Metal result pulls the GTX 750's average down despite its wins in OpenCL and Vulkan. If only the two shared tests are considered, the GTX 750 is clearly ahead. If the full recorded benchmark suite is considered, the Quadro K1200 has the higher average score and percentile rank.

For a buyer choosing between these two, the decision hinges on workload. The GTX 750 offers superior raw compute in the two measured APIs and a lower launch MSRP of 119 USD. The Quadro K1200 offers four times the memory, four mini-DisplayPort outputs, lower power draw, and a better overall average score across all recorded benchmarks. The GTX 750 is the compute winner; the Quadro K1200 is the professional workstation card.
