AMD Radeon HD 8750M vs NVIDIA Quadro M4000 Comparison

Head-to-Head Benchmarks

The recorded data contains only one direct head-to-head comparison between these two GPUs: the Geekbench OpenCL test. In that benchmark, the NVIDIA Quadro M4000 delivers a score of 19118, while the AMD Radeon HD 8750M manages 5970. That is a delta of -68.8% for the AMD part, meaning the Quadro M4000 is more than three times faster in raw compute throughput as measured by OpenCL.

This is a decisive victory for the NVIDIA card, and it is not a close contest. The gap is so wide that the AMD Radeon HD 8750M would need to nearly quadruple its score to match the Quadro M4000 in this specific workload. The OpenCL benchmark exercises general-purpose compute, and the data shows the Maxwell 2.0 architecture with its 1664 shading units simply overwhelms the GCN 1.0 part with 384 shading units.

Looking at the broader database context, the AMD Radeon HD 8750M has an average benchmark score of 5970, while the NVIDIA Quadro M4000 averages 5467. This seems counterintuitive given the head-to-head result, but it reflects the different benchmark suites recorded for each card. The Quadro M4000 has additional results from 3DMark and PassMark tests, including a PassMark G3D score of 6680 and a PassMark GPU Compute score of 2660. Those extra data points pull its average down, whereas the AMD card only has the one Geekbench OpenCL result.

The percentile rankings tell a similar story. The AMD Radeon HD 8750M sits at the 34th percentile of all GPUs in the database, while the NVIDIA Quadro M4000 rests at the 32nd percentile. Despite the massive OpenCL gap, both cards occupy the same general tier of overall performance when all recorded benchmarks are considered. This is because the Quadro M4000's additional benchmark scores, particularly the PassMark DirectX 9 result of 113 and the PassMark G2D score of 673, are not exceptional on an absolute scale.

The direct comparison, however, leaves no ambiguity. In the only test where both cards appear, the NVIDIA Quadro M4000 wins outright with a 68.8% advantage. There are zero benchmark wins for the AMD Radeon HD 8750M in the head-to-head data.

Architecture Differences

The AMD Radeon HD 8750M is built on GCN 1.0 architecture with the Mars chip, fabricated on a 28 nm process at TSMC. The NVIDIA Quadro M4000 uses Maxwell 2.0 architecture with the GM204 chip, also on a 28 nm process at TSMC. Both are mature process nodes, but the silicon designs diverge significantly.

The transistor counts reveal the scale difference. AMD packs 950 million transistors into a die size of 77 mm², giving a transistor density of 12.3M per mm². NVIDIA crams 5,200 million transistors into a 398 mm² die, achieving 13.1M per mm². The NVIDIA chip is over five times larger by transistor count and over four times larger by die area, which explains the massive difference in shading units, TMUs, and ROPs.

Clock behavior differs as well. The AMD Radeon HD 8750M has a base clock of 775 MHz and a boost clock of 825 MHz. The NVIDIA Quadro M4000 has no base or boost clock listed in the database, so direct clock comparisons are impossible. However, the memory clocks tell a different story: AMD runs its memory at 900 MHz with 1800 Mbps effective, while NVIDIA runs at 1502 MHz with 6 Gbps effective.

The API support shows generational progression. AMD supports DirectX 12 (11_1), which is a feature level limitation, while NVIDIA supports DirectX 12 (12_1), the full feature set. Both support OpenGL 4.6, but NVIDIA has a newer Vulkan version at 1.4 compared to AMD's 1.2.170. For professional workloads that rely on modern graphics APIs, the NVIDIA card has a clear compatibility edge.

The bus interface also differs. AMD uses PCIe 3.0 x8, while NVIDIA uses PCIe 3.0 x16. This doubles the available bandwidth for data transfer between the GPU and the host system, which matters for large datasets in professional applications.

Specification Differences

The two GPUs differ across nearly every major specification category. Memory capacity: AMD has 1024 MB, NVIDIA has 8 GB. Memory type: DDR3 versus GDDR5. Memory bus width: 128 bit versus 256 bit. Memory bandwidth: 28.80 GB/s versus 192.3 GB/s. The NVIDIA card has nearly seven times the bandwidth, which is critical for texture-heavy workloads and large compute buffers.

Compute resources: 384 shading units on AMD versus 1664 on NVIDIA. Texture mapping units: 24 versus 104. Raster output units: 8 versus 64. Pixel rate: 6.600 GPixel/s versus 49.47 GPixel/s. Texture rate: 19.80 GTexel/s versus 80.39 GTexel/s. FP32 performance: 633.6 GFLOPS versus 2.573 TFLOPS. Every computational metric favors the NVIDIA card by a wide margin, typically four to eight times.

Power and physical specifications also differ. The NVIDIA Quadro M4000 has a TDP of 120 W, requires a single 6-pin power connector, and suggests a 300 W power supply. It is a single-slot card measuring 241 mm in length and 111 mm in height. The AMD Radeon HD 8750M has no TDP listed, no power connector info, and no dimensions recorded in the database. The AMD card is clearly designed for mobile or compact systems, while the NVIDIA card is a full desktop professional workstation part.

Display outputs: NVIDIA provides 4x DisplayPort 1.2. AMD has no display output information recorded. The NVIDIA card also has a specific release date of 2015-06-28, while the AMD card launched on 2013-02-25, over two years earlier. The NVIDIA Quadro M4000 lists its predecessor as Quadro Kepler and successor as Quadro Pascal. The AMD Radeon HD 8750M lists predecessor London and successor Gem System.

Where Each One Wins

The NVIDIA Quadro M4000 wins every head-to-head benchmark recorded. It dominates in OpenCL compute, and its specification sheet suggests it will also excel in DirectX 12 workloads with feature level 12_1 support, Vulkan 1.4 compatibility, and substantially higher pixel and texture rates. For professional 3D rendering, CAD, simulation, and GPU compute tasks, the Quadro M4000 is the clear choice based on raw performance metrics.

The AMD Radeon HD 8750M does have one advantage: its percentile ranking is slightly higher at 34 versus 32, and its nearest rivals include the NVIDIA Quadro K4000 with an average score of 5982 and a delta of -0.2%, meaning the AMD card is essentially tied with that older Quadro. The AMD card also has a much lower power footprint implied by its mobile-oriented design, though no TDP is recorded. For legacy applications that only require OpenGL 4.6 or DirectX 11_1, the AMD card may suffice, particularly in systems where the 28.80 GB/s memory bandwidth is acceptable.

The AMD card's transistor density of 12.3M per mm² is slightly lower than NVIDIA's 13.1M per mm², but both are on the same 28 nm process. The AMD card's 77 mm² die size is tiny by comparison, making it suitable for compact or power-constrained environments. The NVIDIA card, with its 398 mm² die and 120 W TDP, requires a proper workstation chassis with adequate cooling and power delivery.

The Verdict

The data points to a straightforward conclusion: the NVIDIA Quadro M4000 is the superior GPU in almost every measurable way. Its 19118 OpenCL score versus 5970 for the AMD Radeon HD 8750M represents a 68.8% performance deficit for the AMD part. With 1664 shading units, 8 GB of GDDR5 memory, 192.3 GB/s of bandwidth, and 2.573 TFLOPS of FP32 compute, the Quadro M4000 is in a different performance class entirely.

The AMD Radeon HD 8750M should only be considered for systems that cannot accommodate the Quadro M4000's physical requirements: a single-slot 241 mm card with a 6-pin power connector and 300 W suggested PSU. The AMD card has no recorded dimensions or power draw, but its 28.80 GB/s bandwidth and 633.6 GFLOPS compute are sufficient for basic 2D workloads, legacy DirectX 11 applications, and light compute tasks. Its 1024 MB memory capacity is severely limiting for modern workloads.

For anyone choosing between these two for professional work, the Quadro M4000 is the only rational pick based on benchmark results. The AMD card's slightly higher percentile ranking (34 versus 32) does not offset the massive compute gap. The Quadro M4000 also offers better API support with DirectX 12_1 and Vulkan 1.4, which future-proofs it for newer applications. The AMD card's DirectX 12 (11_1) support is a generation behind.

The database records no scenario where the AMD Radeon HD 8750M wins. If the workload is OpenCL compute, 3D rendering, or modern graphics APIs, the NVIDIA Quadro M4000 delivers more than three times the performance. The only reason to pick the AMD card is if system constraints make the Quadro M4000 physically impossible to install, and even then, the performance compromise is severe. The verdict from the recorded data is unambiguous: choose the NVIDIA Quadro M4000.
