GPU Comparison

The NVIDIA GeForce GT 740 and NVIDIA Quadro K2000D share the same GK107 chip, but they are aimed at entirely different markets, with the GT 740 serving as a consumer card and the K2000D as a professional workstation solution. The data shows a close performance battle, but the specifications reveal distinct design priorities.

Head-to-Head Benchmarks

The only direct benchmark comparison available is the Geekbench OpenCL test, where the two cards land within a hair of each other. The Quadro K2000D scores 3919, while the GeForce GT 740 scores 3847. That gives the Quadro a narrow 1.8% lead, which is well within the margin of noise for synthetic workloads.

Looking at the broader benchmark landscape, the GT 740’s average score across all tests is 3431, which places it in the 21st percentile of all GPUs. Its closest rival, the NVIDIA Quadro 2000M, scores 3434, a mere 0.1% difference. The GT 740 also edges out the Intel HD Graphics P4600 by 1.2% (3389) and the Intel HD Graphics 530 by 3% (3332). However, it trails the NVIDIA GeForce 920MX by 2.7%, which scores 3528.

The Quadro K2000D has a higher average benchmark score of 3919, placing it in the 23rd percentile of all GPUs. Its nearest competitor, the NVIDIA Quadro 2000D, scores 3930, just 0.3% ahead. The Quadro K2000D also outperforms the NVIDIA Quadro 2000 by 0.5% (3898) and the AMD Radeon R5 Graphics by 0.9% (3883). The only rival it loses to is the NVIDIA GeForce GT 745M, which scores 3953, a 0.9% advantage.

The single head-to-head result shows the Quadro winning, but the margin is too slim to declare a clear victor in compute performance. In raw OpenCL throughput, these are effectively equivalent cards. The differences that matter will show up in features, memory capacity, and power efficiency, not in raw shader output.

Architecture Differences

Both cards are built on the same fundamental architecture. They use the identical GK107 chip from NVIDIA’s Kepler family, manufactured on TSMC’s 28 nm process. Both have exactly 1,270 million transistors packed into a 118 mm² die, giving a transistor density of 10.8M per square millimeter. The shading unit count is equal at 384, with 32 texture mapping units and 16 raster output units.

The compute rates are nearly identical. The GT 740 delivers a pixel rate of 7.944 GPixel/s and a texture rate of 31.78 GTexel/s, while the Quadro K2000D manages 7.632 GPixel/s and 30.53 GTexel/s. Floating point performance is similarly close: the GT 740 offers 762.6 GFLOPS of FP32 compute, and the Quadro produces 732.7 GFLOPS. The GT 740 holds a slight edge in every throughput metric, but the differences are under 4%.

Memory clocks differ noticeably. The GT 740 runs its GDDR5 at 1253 MHz, or 5 Gbps effective, while the Quadro K2000D runs at 1000 MHz, or 4 Gbps effective. This gives the GT 740 a bandwidth advantage of 80.19 GB/s versus 64.00 GB/s on the Quadro. Both use a 128-bit memory bus. However, the Quadro doubles the frame buffer capacity to 2 GB, compared to just 1024 MB on the GT 740.

The feature sets are identical in terms of API support. Both cards support DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. Neither has ray tracing or tensor cores. The bus interface differs: the GT 740 uses PCIe 3.0 x16, while the Quadro K2000D is limited to PCIe 2.0 x16.

Power consumption tells a different story. The GT 740 is rated at 64 W TDP and requires a single 6-pin power connector, while the Quadro K2000D sips just 51 W and needs no external power connector at all. Both cards recommend a 250 W power supply. The GT 740 is a single-slot card measuring 145 mm (5.7 inches) in length. The Quadro is also single-slot but is substantially longer at 202 mm (8 inches) and also has a listed height of 111 mm (4.4 inches).

FAQ

Q: Which card has better raw compute performance in OpenCL?

A: The Quadro K2000D scores 3919 in Geekbench OpenCL, beating the GT 740’s 3847 by 1.8%. However, the GT 740 has a higher theoretical FP32 rate of 762.6 GFLOPS versus 732.7 GFLOPS on the Quadro.

Q: Is the GT 740 faster in memory bandwidth?

A: Yes. The GT 740’s memory runs at 5 Gbps effective, yielding 80.19 GB/s of bandwidth, while the Quadro K2000D runs at 4 Gbps effective for 64.00 GB/s. Both use a 128-bit bus.

Q: Why would someone pick the Quadro K2000D over the GT 740?

A: The Quadro offers twice the memory capacity at 2 GB versus 1024 MB, which is critical for large datasets or high-resolution textures. It also consumes less power at 51 W versus 64 W and requires no external power connector.

Q: Are the two cards based on the same chip?

A: Yes, both use the GK107 chip from the Kepler architecture, with identical transistor counts of 1,270 million and the same 384 shading units, 32 TMUs, and 16 ROPs.

Q: Which card has better API support?

A: They are identical. Both support DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175.

Q: What are the physical differences in size?

A: The GT 740 is 145 mm long, while the Quadro K2000D is 202 mm long and 111 mm tall. Both are single-slot cards.

The Verdict

The benchmark data shows these two cards are effectively tied in raw compute, with the Quadro K2000D leading by only 1.8% in OpenCL. The GT 740 has a slight edge in fill rates and bandwidth, but the Quadro counters with double the memory and lower power draw.

For a user who needs maximum memory capacity for professional workloads, the Quadro K2000D is the clear choice. Its 2 GB frame buffer is double the GT 740’s 1024 MB, and its 51 W TDP means it can run in systems without auxiliary power connectors. The longer 202 mm board may require more case clearance, but the lack of a power connector simplifies installation.

For a user prioritizing raw throughput and bandwidth, the GT 740 is marginally better. It delivers 80.19 GB/s against 64.00 GB/s, and its 762.6 GFLOPS of FP32 compute edges out the Quadro’s 732.7 GFLOPS. The 145 mm length makes it easier to fit in compact cases, and the PCIe 3.0 interface is a generation newer.

The average benchmark scores favor the Quadro: 3919 versus 3431. That places the Quadro in the 23rd percentile of all GPUs and the GT 740 in the 21st percentile. But those averages include different test suites, and the only common test shows a 1.8% difference. The data does not support declaring one a decisive winner in performance; it supports picking based on memory needs and power constraints.
