NVIDIA Quadro 4000M

The NVIDIA Quadro 4000M is a professional mobile GPU built on the Fermi architecture, fabricated by TSMC on a 40 nm process. It integrates 1,950 million transistors on a 332 mm² die, yielding a transistor density of 5.9M per square millimeter. The chip packs 336 shading units, 56 texture mapping units, and 32 raster output units. Memory duties are handled by 2 GB of GDDR5 across a 256-bit bus, providing 80.00 GB/s of bandwidth. In the Geekbench OpenCL benchmark, the Quadro 4000M scores 5,212 points, placing it in the 29th percentile of all GPUs. This analysis examines its performance relative to nearest rivals, its memory subsystem, and its feature set.

Benchmark Performance

The Quadro 4000M’s Geekbench OpenCL score of 5,212 is a representative measure of its compute throughput. This score places it at the 29th percentile among all GPUs in the database, indicating a below-median standing in the broader landscape, but the context of its immediate competitors tells a more nuanced story. The nearest rivals—NVIDIA GeForce 840M, NVIDIA GeForce GTX 760M, AMD Radeon HD 8570M, and AMD Radeon R7 M260X—all fall within a remarkably tight performance envelope. The Quadro 4000M edges out the GeForce 840M by 0.2% (5,212 vs. 5,200), trails the GeForce GTX 760M by 0.4% (5,212 vs. 5,235), and leads both AMD parts by 0.6% (5,212 vs. 5,183 for the HD 8570M and 5,212 vs. 5,179 for the R7 M260X). These deltas are sub-1% and effectively within run-to-run variance, meaning the Quadro 4000M is performance-equivalent to its immediate peers in compute workloads.

The raw compute specifications support this picture. The FP32 throughput of 638.4 GFLOPS is the primary driver of OpenCL performance, while the pixel rate of 6.650 GPixel/s and texture rate of 26.60 GTexel/s reflect its fill-rate capabilities. In a professional context, such numbers are modest by modern standards, but they were competitive in the 2011 timeframe. The 29th percentile ranking suggests that the Quadro 4000M sits below the median of all GPUs, which is expected given its age and mobile form factor. However, within its own generation and segment, it holds its own against the listed rivals, with the GeForce GTX 760M being the only one to claim a (very slight) advantage. The benchmark results indicate that the Quadro 4000M is a balanced mid-range part, neither a performance outlier nor a laggard.

Memory Subsystem

The Quadro 4000M is equipped with 2 GB of GDDR5 memory, a configuration that was common for professional mobile GPUs of its era. The memory interface is a 256-bit bus, which, combined with a memory clock of 625 MHz (2.5 Gbps effective), yields a bandwidth of 80.00 GB/s. This bandwidth figure is a critical metric for memory-bound workloads, such as high-resolution texture rendering or large dataset processing. The 256-bit bus width is wider than what many mainstream mobile GPUs of the time used, and it directly contributes to the 80.00 GB/s throughput. For high-resolution scenarios, the bandwidth is adequate for 1080p and early 1440p workloads, but the 2 GB capacity may become a limiting factor when dealing with very large framebuffers or multi-monitor setups. The memory type and bus width are consistent with the Fermi architecture’s design goals, balancing capacity and speed for professional applications. The lack of any memory overclocking headroom is not addressed in the data, but the specified effective rate of 2.5 Gbps is a fixed characteristic. The 80.00 GB/s figure places the Quadro 4000M in the same bandwidth class as its nearest rivals, though exact comparisons are not available from the provided data.

How It Compares

vs. NVIDIA GeForce 840M: The Quadro 4000M scores 5,212, a 0.2% advantage over the GeForce 840M’s 5,200. This is a negligible difference, making the two effectively interchangeable in OpenCL compute tasks. The 840M is a consumer-oriented part, while the Quadro carries a professional designation, but the benchmark data shows no meaningful performance separation.

vs. NVIDIA GeForce GTX 760M: The GeForce GTX 760M leads with a score of 5,235, giving it a 0.4% edge over the Quadro 4000M’s 5,212. This is the only rival in the list that outperforms the Quadro, albeit by a margin that falls within typical benchmark noise. The GTX 760M’s slight lead does not translate into a practical advantage for most workloads.

vs. AMD Radeon HD 8570M: The Quadro 4000M posts a 0.6% higher score than the Radeon HD 8570M (5,212 vs. 5,183). This is a marginal lead, again within the noise band. The two GPUs are effectively tied, despite their different architectures and vendors.

vs. AMD Radeon R7 M260X: Similarly, the Quadro 4000M is 0.6% ahead of the Radeon R7 M260X (5,212 vs. 5,179). The performance gap is trivial, reinforcing the conclusion that all four rivals occupy the same performance tier. The Quadro 4000M’s position in this cluster is consistent with its mid-range professional status.

FAQ

A: The Quadro 4000M scores 5,212 in the Geekbench OpenCL benchmark, placing it in the 29th percentile of all GPUs.

Q: How much memory bandwidth does the Quadro 4000M have?

A: It has a memory bandwidth of 80.00 GB/s, achieved via 2 GB of GDDR5 on a 256-bit bus with a 625 MHz memory clock (2.5 Gbps effective).

Q: What is the transistor count and die size?

A: The chip contains 1,950 million transistors on a 332 mm² die, fabricated on a 40 nm process by TSMC, with a transistor density of 5.9M per mm².

Q: Does the Quadro 4000M support ray tracing?

A: No. The data lists no ray tracing cores or tensor cores, so hardware-accelerated ray tracing is not supported. The GPU does support DirectX 12 (11_0) and OpenGL 4.6.

Q: What is the TDP and form factor?

A: The TDP is 100 W, and the slot width is MXM Module. It uses an MXM-B (3.0) bus interface and has no power connectors.

Q: When was the Quadro 4000M released?

A: It was released on 2011-02-21, and its production status is end-of-life. Its predecessor is the Quadro FX Mobile and its successor is the Quadro Kepler-M.

Ray Tracing and Feature Set

The Quadro 4000M does not include any dedicated ray tracing cores or tensor cores, as indicated by the null values in the fact pack. Consequently, any ray tracing workload would have to rely on software emulation or compute shaders, which is not a practical approach for real-time rendering. The GPU’s feature set is defined by its Fermi architecture and its API support. It supports DirectX 12 (11_0), which is notable because DirectX 12 is a modern API, but the (11_0) suffix indicates the feature level is limited to DirectX 11.0 capabilities. OpenGL 4.6 is also supported, which is a current version. Vulkan support is not listed, so it cannot be assumed. The display outputs are listed as “Portable Device Dependent,” meaning the actual connectors vary by laptop implementation. Power is supplied through the MXM slot, with no additional power connectors required. The TDP of 100 W is a moderate figure for a mobile GPU, reflecting the balance between performance and thermal constraints. The absence of RT and tensor cores is a clear limitation for modern workloads, but for the intended professional applications of the early 2010s, the feature set was adequate. The GPU’s end-of-life status and 2011 release date further underscore its legacy position in the market.
