AMD Radeon R5 M435 vs NVIDIA Quadro 4000M Comparison

Head-to-Head Benchmarks

The sole recorded benchmark for this comparison is Geekbench OpenCL, and the results show a clear winner. The AMD Radeon R5 M435 scores 5859 points, while the NVIDIA Quadro 4000M scores 5211 points. This gives the AMD part a 12.4% advantage, a decisive margin in compute workloads. In the database's head-to-head tally, the Radeon R5 M435 claims 1 win, with the Quadro 4000M registering 0 wins.

Looking at the percentile context, the Radeon R5 M435 sits at the 33rd percentile of all GPUs, while the Quadro 4000M sits at the 30th percentile. This means the AMD part is slightly better positioned relative to the entire GPU landscape, reinforcing the benchmark delta. The 12.4% lead is not trivial; it places the Radeon in a higher performance tier in this specific OpenCL test.

The nearest rivals for each card provide additional texture. The Radeon R5 M435's closest competitor is the AMD Radeon R7 M465, which scores 5841, a mere 0.3% behind. The Intel UHD Graphics 730 scores 5929, putting it 1.2% ahead of the R5 M435. The AMD Radeon HD 8730M and NVIDIA Quadro K620M both score around 5955 to 5957, each about 1.6% ahead. This suggests that the R5 M435 is clustered tightly with other entry-level mobile GPUs, and its performance is competitive within that group.

The Quadro 4000M's nearest rivals tell a similar story. The NVIDIA GeForce GTX 760M scores 5236, which is 0.5% ahead of the Quadro. The AMD Radeon R7 M260X scores 5161, putting it 1% behind. The NVIDIA Quadro K3100M scores 5154, also 1.1% behind. The NVIDIA GeForce 940M scores 5284, which is 1.4% ahead. The Quadro 4000M is therefore positioned in a tight cluster, but its 5211 score places it below several contemporary mobile parts from both AMD and NVIDIA.

The gap between the two cards is significant enough that in any OpenCL compute workload, the Radeon R5 M435 should be the expected frontrunner. The delta of 12.4% exceeds the variance seen among the nearest rivals, which typically fall within 1.6% of each other. This indicates the performance difference is structural, not a statistical fluke.

The Verdict

For pure compute performance, the data points squarely to the AMD Radeon R5 M435. Its Geekbench OpenCL score of 5859 is 12.4% higher than the Quadro 4000M's 5211. The Radeon also holds a higher percentile rank, 33rd versus 30th. If the task is OpenCL compute, the Radeon is the stronger choice.

However, the Quadro 4000M is not without its own rationale. It is a professional mobile workstation GPU from the Fermi generation, and it comes with a 256-bit memory bus and 80.00 GB/s of bandwidth, compared to the Radeon's 64-bit bus and 36.00 GB/s. In memory-bound scenarios, this bandwidth advantage could matter, even if raw compute is lower. The Quadro also has more shading units (336 versus 320) and more texture mapping units (56 versus 20), which could benefit specific workloads that are texture-heavy rather than compute-heavy.

The Radeon R5 M435, by contrast, uses the GCN 1.0 architecture with a 28 nm process, while the Quadro 4000M uses Fermi on 40 nm. The Radeon supports Vulkan 1.2.170, while the Quadro has no Vulkan support listed. For modern application compatibility, the Radeon has an edge on the API front.

Who should pick which? From the recorded data, the AMD Radeon R5 M435 is the pick for users prioritizing OpenCL compute performance and modern API support. The NVIDIA Quadro 4000M is the pick for users whose workloads depend heavily on memory bandwidth and texture throughput, where its 256-bit interface and higher TMU count could compensate for its lower compute score. Both are end-of-life products, so the choice is about matching the specific workload to the available strengths.

Architecture Differences

The two GPUs come from different architectural eras. The AMD Radeon R5 M435 is based on GCN 1.0, using the Jet chip, built on a 28 nm process at TSMC. The die is 56 mm² and contains 690 million transistors, yielding a transistor density of 12.3 million per mm². The NVIDIA Quadro 4000M uses the Fermi architecture, with the GF104 chip, built on a 40 nm process, also at TSMC. Its die is 332 mm², with 1,950 million transistors, giving a density of 5.9 million per mm².

The architectural philosophies diverge sharply. GCN 1.0 was designed for compute-heavy workloads with a focus on throughput per clock. Fermi was NVIDIA's first generation to introduce a unified compute architecture with strong tessellation and geometry performance. The Radeon's 28 nm node gives it a manufacturing advantage, allowing for a much smaller die and higher transistor density.

The Radeon R5 M435 has 320 shading units, 20 TMUs, and 8 ROPs. The Quadro 4000M has 336 shading units, 56 TMUs, and 32 ROPs. The Quadro's higher TMU and ROP counts are notable, as they directly affect texture fill and pixel fill rates. The recorded texture rate for the Radeon is 20.60 GTexel/s, while the Quadro achieves 26.60 GTexel/s. The pixel rate tells a different story: the Radeon hits 8.240 GPixel/s, while the Quadro is at 6.650 GPixel/s. The Radeon's faster pixel rate is surprising given its lower ROP count, but it is likely due to higher clock speeds on the Radeon.

The Radeon has a base clock of 780 MHz and a boost clock of 1030 MHz, while the Quadro has no listed base or boost clocks. The Radeon's memory runs at 1125 MHz, with an effective 4.5 Gbps, while the Quadro's memory runs at 625 MHz, with an effective 2.5 Gbps. Despite the Radeon's higher memory clock, the Quadro's 256-bit bus gives it a bandwidth advantage: 80.00 GB/s versus 36.00 GB/s.

The FP32 compute figures are close. The Radeon delivers 659.2 GFLOPS, while the Quadro delivers 638.4 GFLOPS. The Radeon is 3.3% ahead in raw floating-point throughput, which aligns with its OpenCL benchmark lead. Neither card lists FP16 support.

Specification Differences

The two cards differ on several specification fields. The process node differs: the Radeon R5 M435 uses 28 nm, while the Quadro 4000M uses 40 nm. The transistor count differs (690 million versus 1,950 million), as does the die size (56 mm² versus 332 mm²) and transistor density (12.3M / mm² versus 5.9M / mm²).

Clock speeds are only listed for the Radeon, with a base of 780 MHz and boost of 1030 MHz. The Quadro has no base or boost clock listed. Memory clocks differ significantly: the Radeon has a 1125 MHz memory clock (4.5 Gbps effective), while the Quadro has a 625 MHz memory clock (2.5 Gbps effective).

Memory bus width is a major differentiator: 64-bit for the Radeon versus 256-bit for the Quadro. This leads to the bandwidth gap: 36.00 GB/s versus 80.00 GB/s. Shading units are close (320 versus 336), but TMUs (20 versus 56) and ROPs (8 versus 32) are heavily in the Quadro's favor.

Pixel rate and texture rate differ: the Radeon has a higher pixel rate (8.240 GPixel/s versus 6.650 GPixel/s), but the Quadro has a higher texture rate (26.60 GTexel/s versus 20.60 GTexel/s). FP32 is nearly identical, with the Radeon slightly ahead at 659.2 GFLOPS versus 638.4 GFLOPS.

The Quadro 4000M lists a TDP of 100 W, while the Radeon has no TDP listed. The slot width differs: the Radeon is listed as "IGP" (integrated graphics processor), while the Quadro is an "MXM Module". The bus interface also differs: the Radeon uses PCIe 3.0 x8, while the Quadro uses MXM-B (3.0). The Quadro has no power connectors listed, and the Radeon has none listed either.

API support differs in key ways. The Radeon supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Quadro supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support listed. Release dates differ: the Radeon was released in May 2016, while the Quadro was released in February 2011.
