NVIDIA GeForce GTX 960M vs NVIDIA Quadro K5000 Comparison

The GeForce GTX 960M and Quadro K5000 sit at nearly identical average benchmark scores, with the mobile Maxwell chip edging out the older Kepler workstation card by a razor-thin 0.1%. Both hold the 46th percentile among all GPUs, making them statistical peers in raw compute despite their vastly different designs and target markets. The data, however, reveals a clear split in workload-specific performance that matters far more than the aggregate score suggests.

Head-to-Head Benchmarks

The two available head-to-head benchmarks tell a consistent story: the Quadro K5000 is the faster card, but the margin depends entirely on the test. In Geekbench OpenCL, the K5000 scores 11,418 against the GTX 960M’s 11,045, a modest 3.3% advantage. That is a narrow lead, well within the range where driver optimizations or thermal conditions on a mobile platform could flip the result on any given run. The GTX 960M’s 640 shading units running at 1097 MHz boost to 1176 MHz simply cannot overcome the K5000’s raw hardware advantage in this compute-heavy workload.

The Vulkan test is where the gap becomes decisive. The Quadro K5000 posts 11,169, which is 26.2% higher than the GTX 960M’s 8,245. That is not a marginal difference; it is a generational-class separation in graphics API performance. The K5000’s 1,536 shading units and 128 texture mapping units, paired with a 256-bit memory bus delivering 172.8 GB/s, dwarf the GTX 960M’s 40 TMUs and 80.19 GB/s of bandwidth. In Vulkan workloads that scale with shader count and memory throughput, the GTX 960M is simply outgunned.

The aggregate benchmark scores reinforce this picture. The GTX 960M averages 9,645 across its two tests, while the K5000 averages 9,637 across three tests. The OpenCL scores are nearly identical, but the K5000’s much stronger Vulkan showing is what gives it the overall edge in the head-to-head comparisons. Notably, the GTX 960M has no Metal benchmark result, while the K5000 scores 6,324 in that API, suggesting the workstation card also carries compatibility advantages that the mobile chip cannot match.

FAQ

The Verdict

The data points to a clear but nuanced conclusion: the Quadro K5000 is the stronger performer, but only in specific workloads. If your benchmark priority is Vulkan-based graphics or compute, the K5000’s 26.2% lead is decisive and should drive the purchasing decision. If you are working primarily in OpenCL, the 3.3% difference is negligible, and other factors like power consumption or form factor will matter more.

The GTX 960M’s case rests on its efficiency and mobility. It draws 75 W versus the K5000’s 122 W, and it comes as an MXM module with no power connectors, making it suitable for laptops. The K5000 is a dual-slot desktop card requiring a 1x 6-pin connector and a 300 W power supply, with a 267 mm length. For a compact or portable build, the GTX 960M is the only practical option, and its OpenCL performance is close enough that you would not feel shortchanged in that API.

For desktop workstation users who need maximum throughput and can accommodate a full-size card, the K5000 wins outright. The Vulkan advantage alone justifies its selection, and its higher pixel rate (22.59 GPixel/s) and texture rate (90.37 GTexel/s) make it better suited for graphics-heavy tasks. The GTX 960M is not a bad card; it is simply a different tool, and the benchmarks show that tool is best used where portability outweighs peak performance.

Specification Differences

The two cards differ across nearly every major specification, starting with the chip itself. The GTX 960M uses the GM107 chip built on a 148 mm² die with 1,870 million transistors, while the K5000 uses the GK104 chip on a 294 mm² die with 3,540 million transistors. The K5000’s die is nearly double the size, and its transistor count is 89% higher.

Clock speeds favor the GTX 960M, which runs at 1097 MHz base and 1176 MHz boost, while the K5000 is locked at 706 MHz for both base and boost. Memory clocks also differ slightly, with the GTX 960M at 1253 MHz (5 Gbps effective) and the K5000 at 1350 MHz (5.4 Gbps effective). The K5000’s memory bus width of 256 bit versus the GTX 960M’s 128 bit produces a massive bandwidth gap: 172.8 GB/s versus 80.19 GB/s.

The compute resources are heavily skewed toward the K5000. It has 1,536 shading units, 128 TMUs, and 32 ROPs, while the GTX 960M has 640 shading units, 40 TMUs, and 16 ROPs. This translates to 2.169 TFLOPS of FP32 performance for the K5000 versus 1.505 TFLOPS for the GTX 960M. Power draw differs significantly as well: the GTX 960M is rated at 75 W with no power connectors, while the K5000 draws 122 W and requires a 1x 6-pin connector.

Form factor and connectivity are entirely different. The GTX 960M is an MXM module using an MXM-B (3.0) interface with portable-device-dependent display outputs. The K5000 is a dual-slot PCIe 2.0 x16 card measuring 267 mm in length and 111 mm in height, with 2x DVI and 2x DisplayPort 1.2 outputs. The K5000 also has a launch MSRP of 2,499 USD, while the GTX 960M has no listed launch price.

Architecture Differences

The architectural split is Maxwell versus Kepler, and that difference explains much of the performance gap. The GTX 960M is built on the Maxwell architecture, which emphasizes efficiency and higher clock speeds. It achieves 12.6 million transistors per mm² on a 28 nm TSMC process, while the K5000’s Kepler design manages 12.0 million transistors per mm² on the same 28 nm node. Both are 28 nm parts from TSMC, so the process node is not a differentiator.

The K5000’s GK104 chip is a much larger, more complex design with over 3.5 billion transistors. Kepler was designed for high-throughput desktop computing, and its 1,536 shading units reflect that ambition. Maxwell, by contrast, is a more streamlined architecture that achieves competitive performance with far fewer resources by relying on higher clocks and better instruction efficiency. The GTX 960M’s 1.505 TFLOPS from 640 cores at 1176 MHz boost versus the K5000’s 2.169 TFLOPS from 1,536 cores at 706 MHz shows this trade-off clearly.

Memory architecture also differs fundamentally. The K5000’s 256-bit bus is a desktop-class design that enables 172.8 GB/s of bandwidth, essential for large texture sets and high-resolution workloads. The GTX 960M’s 128-bit bus is a mobile compromise, halving bandwidth to 80.19 GB/s. The K5000’s dual DisplayPort 1.2 outputs and dual DVI connectors indicate professional display support, while the GTX 960M’s outputs are dependent on the portable device it is installed in.

API support shows a minor but notable difference: the GTX 960M supports Vulkan 1.4, while the K5000 supports Vulkan 1.2.175. Both support DirectX 12 (11_0) and OpenGL 4.6, so compatibility with modern software is not a differentiator. The K5000’s additional Metal benchmark score of 6,324, though not a head-to-head comparison, suggests it has broader API coverage than the GTX 960M, which has no Metal result.

Where Each One Wins

The Quadro K5000 wins in every head-to-head benchmark, but the scope of that victory is what matters. Its 26.2% Vulkan advantage makes it the clear choice for any workload that leverages that API, including modern game engines, compute shaders, and cross-platform graphics. Its 3.3% OpenCL lead is smaller but consistent, and its higher pixel and texture rates (22.59 GPixel/s and 90.37 GTexel/s) indicate better performance in fill-rate-bound scenarios.

The GTX 960M’s wins are not in performance but in practicality. It consumes 75 W versus the K5000’s 122 W, and its MXM form factor with no power connectors makes it installable in laptops where a dual-slot desktop card is physically impossible. Its higher clock speeds (1097 MHz base, 1176 MHz boost) hint at better responsiveness in clock-bound workloads, even if the aggregate benchmarks do not show it. The GTX 960M also supports Vulkan 1.4, which is a newer API version than the K5000’s 1.2.175, offering theoretical forward-compatibility.

For a desktop workstation with room for a full-length card, the K5000 is the superior choice. Its memory bandwidth alone is a decisive factor for texture-heavy professional applications. For a mobile workstation or a compact build, the GTX 960M is the only option that fits, and its OpenCL performance is close enough to the K5000 that the practical difference will be minimal. The data does not support calling one card universally better; it supports matching the card to the physical and performance requirements of the system.
