NVIDIA GeForce GT 745M vs NVIDIA Quadro 2000M Comparison

The benchmark data shows a clear, if narrow, victory for the NVIDIA GeForce GT 745M over the NVIDIA Quadro 2000M. In the only shared benchmark test, the GT 745M outperforms the Quadro, though the margin is modest. However, the architectural gap between the two mobile GPUs is substantial, revealing that the GT 745M is the more modern and efficient design, while the Quadro 2000M relies on an older, power-hungry architecture.

Head-to-Head Benchmarks

The sole direct comparison available is the Geekbench OpenCL test. Here, the NVIDIA GeForce GT 745M scores 3580, while the NVIDIA Quadro 2000M scores 3434. This gives the GT 745M a 4.1% advantage. While this is a clear win for the GT 745M, the performance delta is not transformative. It is a measurable lead, but not one that fundamentally changes the character of either GPU in compute workloads.

Looking at the broader context provided by the nearest rivals, both GPUs occupy a similar performance tier. The Quadro 2000M’s average score of 3434 places it just 0.1% behind the NVIDIA GeForce GT 740 and 1.3% ahead of the Intel HD Graphics P4600. It also sits 2.7% behind the NVIDIA GeForce 920MX. The GT 745M, with an average score of 3953, is effectively tied with the AMD Radeon R5 M420, which is only 0.1% faster. This data suggests that while the GT 745M wins this head-to-head, neither GPU is a performance outlier in its respective peer group.

The GT 745M’s win in the OpenCL test is its only recorded victory, giving it a 1-0 win record against the Quadro 2000M. The Quadro 2000M, by contrast, has no benchmark wins in this comparison. The deltaPct of -4.1% from the perspective of the Quadro 2000M indicates the performance gap, but the absolute difference of 146 points is small enough that real-world application performance would likely feel very similar for many tasks.

Architecture Differences

The two GPUs come from different architectural eras. The NVIDIA Quadro 2000M is built on the Fermi architecture, using the GF106 chip, whereas the NVIDIA GeForce GT 745M utilizes the Kepler architecture with the GK107 chip. This generational shift is immediately apparent in the manufacturing process. The Quadro 2000M uses a 40 nm process, while the GT 745M uses a more advanced 28 nm process. Both are fabricated by TSMC.

The die size and transistor density tell a compelling story of efficiency. The Quadro 2000M has a die size of 238 mm² and houses 1,170 million transistors, resulting in a transistor density of 4.9M / mm². In contrast, the GT 745M packs 1,270 million transistors into a much smaller 118 mm² die, achieving a transistor density of 10.8M / mm². This means the GT 745M fits more transistors into half the physical space, a direct consequence of the newer manufacturing node. This efficiency is reflected in power consumption, with the Quadro 2000M having a TDP of 55 W compared to the GT 745M’s 45 W.

Memory technology also differs significantly. The Quadro 2000M comes with 2 GB of DDR3 memory running at an effective speed of 1800 Mbps, delivering a bandwidth of 28.80 GB/s over a 128-bit bus. The GT 745M also has 2 GB of memory and a 128-bit bus, but it uses faster GDDR5 memory. Its memory clock is 4 Gbps effective, which yields a bandwidth of 64.00 GB/s. This is more than double the memory bandwidth of the Quadro 2000M, a critical advantage for memory-intensive workloads.

The compute configurations are also distinct. The Quadro 2000M has 192 shading units, 32 TMUs, and 16 ROPs. The GT 745M doubles the shading units to 384, while keeping the same 32 TMUs and 16 ROPs. Despite the shading unit difference, the raw throughput numbers are nearly identical. The Quadro 2000M has a pixel rate of 4.400 GPixel/s and a texture rate of 17.60 GTexel/s, while the GT 745M has 4.392 GPixel/s and 17.57 GTexel/s. Their FP32 performance is also a virtual tie, with the Quadro at 422.4 GFLOPS and the GT 745M at 421.6 GFLOPS. The GT 745M is the only one of the two with recorded Vulkan support, listing version 1.2.175.

Where Each One Wins

Based strictly on the data, the NVIDIA GeForce GT 745M is the winner in the one benchmark category where they are directly compared. Its 3580 OpenCL score against the Quadro 2000M’s 3434 makes it the faster option for general-purpose compute tasks that leverage OpenCL. The GT 745M also holds a significant advantage in memory bandwidth, with 64.00 GB/s versus 28.80 GB/s. This suggests it would have a clear edge in scenarios that are bandwidth-limited, such as high-resolution texture processing or certain types of compute workloads.

The GT 745M’s higher average benchmark score of 3953, compared to the Quadro 2000M’s 3434, further cements its position as the more capable GPU overall. Its higher percentile rank of 23 versus the Quadro’s 21 indicates it outperforms a larger fraction of all GPUs in the database. For a user prioritizing raw compute performance and memory throughput, the GT 745M is the clear choice.

The NVIDIA Quadro 2000M, despite its age and architectural differences, does not have a single benchmark win to its name in this comparison. Its performance is closely matched to the GT 745M in pixel and texture rates, but it does not surpass it in any measured category. Its only potential advantage lies in its position as a professional-grade Quadro product, but the data provided does not include any professional application benchmarks to substantiate a win there.

The Verdict

The NVIDIA GeForce GT 745M is the superior GPU according to the benchmark data. It wins the only head-to-head OpenCL test by 4.1% and offers more than double the memory bandwidth of the Quadro 2000M. The GT 745M’s data also shows a higher average benchmark score and a better percentile ranking, indicating stronger overall performance relative to the entire GPU landscape.

The NVIDIA Quadro 2000M should be chosen by users who specifically require a Fermi-based Quadro mobile workstation GPU. Its datasheet shows a 55 W TDP and MXM Module slot width, which may be a requirement for legacy or specialized hardware configurations. However, from a pure performance standpoint, the data does not favor it.

For virtually all performance-driven scenarios, the NVIDIA GeForce GT 745M is the pick. It delivers better compute performance, superior memory bandwidth, and does so with a lower 45 W TDP. Its newer Kepler architecture and 28 nm process node provide a clear efficiency advantage. The GT 745M is the more modern, faster, and more efficient solution.
