Where Each One Wins

The GTX 675MX dominates in compute throughput. Its OpenCL score of 10,723 is 47.1% above the Quadro 5000's 7,289, and its FP32 output is 1,255.7 GFLOPS versus 722.3 GFLOPS. The texture rate also heavily favors the mobile card: 52.32 GTexel/s compared to 22.57 GTexel/s, a difference that benefits shader-heavy and texture-bound workloads.

The Quadro 5000 counters with advantages in memory capacity and bandwidth. It carries 2.5 GB of GDDR5 across a 320-bit bus for 120.0 GB/s, slightly above the GTX 675MX's 2 GB on 256-bit for 115.2 GB/s. Its 40 ROPs also exceed the GTX 675MX's 32 ROPs, giving it a higher pixel throughput ceiling in certain rasterization scenarios, though its actual pixel rate of 11.29 GPixel/s trails the GTX 675MX's 13.08 GPixel/s.

The Quadro 5000 is a desktop workstation card with a dual-slot form factor, 248 mm length, 111 mm height, and DVI plus dual DisplayPort outputs. It supports a 450 W suggested PSU. The GTX 675MX is an MXM module for portable devices, with display outputs described as portable device dependent. For users needing a fixed workstation card with professional display connectivity, the Quadro 5000 is the practical choice; for raw compute in a mobile chassis, the GTX 675MX wins outright.

Specification Differences

The GTX 675MX uses the GK104 chip on a 28 nm TSMC process, packing 3,540 million transistors into a 294 mm² die for a density of 12.0M transistors per mm². The Quadro 5000 uses the GF100 chip on a 40 nm TSMC process, with 3,100 million transistors across a much larger 529 mm² die and a density of only 5.9M per mm².

The GTX 675MX fields 960 shading units, 80 TMUs, and 32 ROPs. The Quadro 5000 has 352 shading units, 44 TMUs, and 40 ROPs. The GTX 675MX therefore has more than 2.7 times the shading units and nearly double the texture units, while the Quadro has 8 additional ROPs.

Memory configurations differ in size and bus width: 2 GB on a 256-bit bus for the GTX 675MX versus 2.5 GB on a 320-bit bus for the Quadro 5000. Memory clocks are 900 MHz (3.6 Gbps effective) for the GTX 675MX and 750 MHz (3 Gbps effective) for the Quadro 5000. The resulting bandwidths are close: 115.2 GB/s versus 120.0 GB/s.

The GTX 675MX is rated at 100 W TDP and uses an MXM-B (3.0) interface with no power connector. The Quadro 5000 draws 152 W, is dual-slot, uses PCIe 2.0 x16, and requires a 6-pin connector. API support differs only in Vulkan: the GTX 675MX supports Vulkan 1.2.175, while the Quadro 5000 has no Vulkan support. Both support DirectX 12 (11_0) and OpenGL 4.6.

Release timing also differs: the GTX 675MX launched in the GeForce 600M generation on 2012-09-30, while the Quadro 5000 launched in the Quadro Fermi (x000) generation on 2011-02-22. The GTX 675MX follows the GeForce 500M series and precedes the GeForce 700M series; the Quadro 5000 follows Quadro FX Tesla and precedes Quadro Kepler.

Head-to-Head Benchmarks

The database records one direct comparison: Geekbench OpenCL. The GTX 675MX scores 10,723 and the Quadro 5000 scores 7,289. That is a 47.1% gap, a decisive margin that places the GTX 675MX firmly above its rival in compute workloads. In percentile terms, the GTX 675MX ranks at the 43rd percentile of all GPUs, while the Quadro 5000 ranks at the 40th, a modest overall gap despite the large OpenCL delta.

Context from nearest rivals reinforces the split. The GTX 675MX averages 8,427 across benchmarks, nearly matching the AMD Radeon 880M at 8,436 (0.1% slower) and the NVIDIA GeForce MX330 at 8,458 (0.4% slower). The Quadro 5000 averages 7,289, sitting just above the GeForce GTX 750 at 7,222 (0.9% slower) and the AMD Radeon Vega 8 Mobile at 7,203 (1.2% slower). In other words, the GTX 675MX competes with a newer integrated-class GPU tier, while the Quadro 5000 aligns with older desktop discrete cards.

The FP32 figures tell a similar story. The GTX 675MX delivers 1,255.7 GFLOPS, which is about 74% higher than the Quadro 5000's 722.3 GFLOPS. Texture rate follows the same pattern: 52.32 GTexel/s versus 22.57 GTexel/s. Pixel rate is closer, 13.08 GPixel/s versus 11.29 GPixel/s, reflecting the Quadro's higher ROP count partially offsetting its lower core clocks and shader throughput.

Memory bandwidth is the one metric where the Quadro 5000 takes a small lead. Its 120.0 GB/s is 4.2% higher than the GTX 675MX's 115.2 GB/s. That advantage, however, does not translate into a benchmark win in the recorded data. The GTX 675MX wins the only direct head-to-head test, and it holds the higher average score across the board.

Architecture Differences

The two cards come from different NVIDIA architectures. The GTX 675MX is built on Kepler (chip GK104), while the Quadro 5000 is built on Fermi (chip GF100). Kepler was designed for higher shader counts and better power efficiency, which shows in the 28 nm process versus 40 nm. The GTX 675MX fits 3,540 million transistors into 294 mm², while the Quadro 5000 spreads 3,100 million transistors across 529 mm². The transistor density gap, 12.0M per mm² versus 5.9M per mm², reflects the two process generations between them.

Shader architecture diverges sharply. Kepler's 960 shading units give the GTX 675MX a large compute advantage, and its 80 TMUs double the Quadro's 44. The Quadro 5000 counters with 40 ROPs against 32, a workstation-oriented balance that favors fill-rate tasks. Despite that, the GTX 675MX still posts a higher pixel rate: 13.08 GPixel/s versus 11.29 GPixel/s.

The memory subsystem differs in width and capacity but lands at similar bandwidth. The GTX 675MX uses 2 GB of GDDR5 at 900 MHz (3.6 Gbps effective) on a 256-bit bus for 115.2 GB/s. The Quadro 5000 uses 2.5 GB of GDDR5 at 750 MHz (3 Gbps effective) on a 320-bit bus for 120.0 GB/s. The Quadro's extra 0.5 GB and wider bus give it a slight capacity and bandwidth edge, but the GTX 675MX's faster memory clock narrows the gap.

Features also differ. The GTX 675MX supports Vulkan 1.2.175; the Quadro 5000 does not list Vulkan support. Both support DirectX 12 (11_0) and OpenGL 4.6. The GTX 675MX uses an MXM-B (3.0) bus interface and is a portable device dependent display output, while the Quadro 5000 uses PCIe 2.0 x16 with DVI and dual DisplayPort outputs. The Quadro 5000 is a dual-slot desktop card measuring 248 mm by 111 mm, with a 6-pin power connector and a 450 W suggested PSU, while the GTX 675MX is a 100 W MXM module with no power connector.

Thermal and power design reflect their intended platforms. The GTX 675MX's 100 W TDP suits laptops and compact systems, whereas the Quadro 5000's 152 W TDP requires desktop airflow and a beefier power supply. Both are end-of-life products, but they target different segments: the GTX 675MX is a mobile gaming GPU from the GeForce 600M generation, and the Quadro 5000 is a professional workstation card from the Quadro Fermi line. Their architectures embody those distinct goals, with Kepler prioritizing compute density and efficiency and Fermi prioritizing a wider memory bus and ROP count for professional rendering tasks.
