NVIDIA GeForce GTX TITAN X vs NVIDIA Quadro M6000 Comparison

FAQ

Q: Which GPU wins more benchmarks in the database, the Quadro M6000 or the GTX TITAN X?

A: The GeForce GTX TITAN X wins both recorded head-to-head tests. It leads in Geekbench OpenCL with a score of 41471 versus 39688, and in Geekbench Vulkan with 49397 versus 46913. The database shows no benchmark wins for the Quadro M6000 in this comparison.

Q: How big is the performance gap in the OpenCL test?

A: The GTX TITAN X is 4.3% ahead of the Quadro M6000 in Geekbench OpenCL. That delta translates to a raw score difference of 1783 points, with the TITAN X scoring 41471 against the M6000's 39688.

Q: Which card has a higher base clock speed?

A: The GTX TITAN X runs a 1000 MHz base clock, while the Quadro M6000 is set to 988 MHz. On the boost side, the M6000 actually boosts higher at 1114 MHz, compared to the TITAN X's 1089 MHz.

Q: Do the two cards share the same memory configuration?

A: Both cards use 12 GB of GDDR5 memory on a 384 bit bus. However, the TITAN X runs its memory at 1753 MHz (7 Gbps effective) for 336.6 GB/s bandwidth, while the M6000 runs at 1653 MHz (6.6 Gbps effective) for 317.4 GB/s.

Q: What are the power connector requirements for each?

A: The Quadro M6000 uses a single 8-pin connector. The GTX TITAN X requires one 6-pin plus one 8-pin connector. Both share a 250 W TDP and a 600 W suggested PSU rating.

Q: How do their overall database percentiles compare?

A: The Quadro M6000 sits in the 84th percentile among all GPUs, while the GTX TITAN X lands in the 80th percentile. This puts the M6000 slightly higher in the overall distribution despite losing the head-to-head tests.

Architecture Differences

Both cards are built on the same GM200 chip using Maxwell 2.0 architecture, fabricated by TSMC on a 28 nm process. The transistor count is identical at 8,000 million, and the die size is exactly 601 mm², yielding the same transistor density of 13.3M per mm². This is the same silicon, but the products are tuned for different markets. The Quadro M6000 belongs to the Quadro Maxwell (Mx000) generation, while the GTX TITAN X is part of the GeForce 900 family.

The shading unit count matches at 3072, as do the texture mapping units at 192 and the render output units at 96. Neither card features dedicated ray tracing or tensor cores, consistent with the Maxwell generation. The API support is identical: DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 3.0 x16 interface and occupy a dual-slot form factor.

The key architectural difference lies in clock behavior. The GTX TITAN X has a higher base clock at 1000 MHz versus 988 MHz on the M6000, but the Quadro has the higher boost clock at 1114 MHz versus 1089 MHz. Memory clocking also diverges: the TITAN X runs at 1753 MHz (7 Gbps effective) versus the M6000's 1653 MHz (6.6 Gbps effective). The display output configuration differs as well, with the M6000 offering 1x DVI and 4x DisplayPort 1.2, while the TITAN X provides 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2. The TITAN X also carries an extra 6-pin power connector, though both draw 250 W.

Head-to-Head Benchmarks

The recorded data covers two tests, and the GTX TITAN X wins both. In Geekbench OpenCL, the TITAN X scores 41471 against the M6000's 39688, a margin of 4.3%. This is a meaningful gap for two cards that share the same chip, core counts, and memory size. The TITAN X's higher memory clock (1753 MHz versus 1653 MHz) and higher base clock (1000 MHz versus 988 MHz) contribute directly to this result. The bandwidth advantage is 336.6 GB/s versus 317.4 GB/s, a difference of about 6% that shows up in compute workloads.

In Geekbench Vulkan, the TITAN X extends its lead slightly. It scores 49397 versus 46913, a 5% delta. This test shows the TITAN X pulling ahead by 2484 points, a larger absolute margin than the OpenCL gap. The Vulkan result is notable because both cards expose the same API feature level (12_1), so the difference comes down to clock speeds and memory throughput rather than architectural capability.

The Quadro M6000 does not win either test. Its best showing is the OpenCL result where it trails by 4.3%, and its worst is Vulkan where the deficit grows to 5%. The overall average benchmark score in the database reflects this: the M6000 averages 43301 across all recorded tests, while the TITAN X averages 36530. However, that average is skewed because the TITAN X also has a Geekbench Metal score of 18723, which drags its mean down. The two head-to-head tests are the cleanest comparison, and they both favor the TITAN X.

The specification table shows a clear pattern. The TITAN X runs higher memory clocks and a higher base clock, which explains its benchmark wins. The M6000 counters with a higher boost clock and slightly higher pixel, texture, and FP32 rates. The FP32 output is 6.844 TFLOPS for the M6000 versus 6.691 TFLOPS for the TITAN X, a 2.3% advantage for the Quadro that does not translate into wins in the recorded tests. The M6000 also omits HDMI output, while the TITAN X includes HDMI 2.0.

Where Each One Wins

The GTX TITAN X wins in compute workloads as measured by Geekbench OpenCL and Vulkan. The data shows a 4.3% lead in OpenCL and a 5% lead in Vulkan. This makes the TITAN X the better choice for anyone prioritizing raw benchmark performance in these API environments. The higher memory bandwidth (336.6 GB/s versus 317.4 GB/s) and higher base clock (1000 MHz versus 988 MHz) are the likely drivers. The TITAN X also offers HDMI 2.0 output, which matters for consumer display setups.

The Quadro M6000 wins on theoretical peak rates. Its pixel rate is 106.9 GPixel/s versus 104.5 GPixel/s, its texture rate is 213.9 GTexel/s versus 209.1 GTexel/s, and its FP32 throughput is 6.844 TFLOPS versus 6.691 TFLOPS. These are small margins, between 1% and 2.3%, but they are consistent across all three metrics. The M6000 also boosts higher at 1114 MHz versus 1089 MHz, which may help in sustained workloads that keep the GPU at boost clocks. For users who value the Quadro's display output arrangement, the 4x DisplayPort 1.2 configuration supports multi-monitor professional setups without needing HDMI.

The database percentile ranking favors the M6000 at 84 versus 80 for the TITAN X. This suggests that across the entire benchmark suite, the M6000 sits higher relative to all other GPUs, even though it loses the two direct comparisons. The TITAN X's Metal score of 18723 is notably low and pulls its average down, while the M6000 has no Metal score recorded. This means the M6000's average of 43301 is based on fewer tests, all of which are relatively strong.

The Verdict

The data points to the GTX TITAN X as the faster card in direct comparison. It wins both head-to-head tests, with margins of 4.3% in OpenCL and 5% in Vulkan. The TITAN X achieves this through higher memory bandwidth (336.6 GB/s versus 317.4 GB/s) and a higher base clock (1000 MHz versus 988 MHz). For any user who prioritizes benchmark performance in OpenCL or Vulkan workloads, the TITAN X is the clear pick.

The Quadro M6000 does have advantages, but they are theoretical rather than measured. It leads in pixel rate, texture rate, and FP32 throughput, all by 1% to 2.3%. It also holds a higher boost clock at 1114 MHz. However, none of these advantages produce a win in the recorded tests. The M6000's 84th percentile ranking versus the TITAN X's 80th is interesting, but that ranking includes different test sets and does not override the direct comparison results.

The choice between the two should come down to workload specifics. The TITAN X is the better performer in the benchmarks that matter for compute and graphics APIs. The M6000 is the better choice if the user needs 4x DisplayPort outputs, prefers the Quadro driver ecosystem, or values the slightly higher FP32 peak. The TITAN X carries a launch MSRP of 999 USD, but this is not a factor in the performance verdict. Based strictly on the recorded data, the TITAN X wins the head-to-head, and the M6000 wins on paper specs that do not translate to benchmark victories.
