AMD Radeon R8 M445DX vs NVIDIA Quadro 2000D Comparison

Where Each One Wins

The benchmark data splits cleanly between these two GPUs. The AMD Radeon R8 M445DX wins the only head-to-head benchmark recorded in the database, the Geekbench OpenCL test, with a score of 4727 against 3930 for the NVIDIA Quadro 2000D. That is a 16.9% advantage for the AMD part, and it is the sole benchmark where both cards appear in the same comparison.

The NVIDIA Quadro 2000D has no benchmark wins in the head-to-head data. Its score of 3930 places it at the 23rd percentile of all GPUs in the database, while the AMD Radeon R8 M445DX sits at the 27th percentile. The AMD card outperforms the NVIDIA card in raw compute throughput as measured by OpenCL, which is the primary workload category represented in these records.

For use-case segmentation, the AMD Radeon R8 M445DX is the stronger choice for OpenCL compute workloads, which typically include general-purpose GPU tasks such as image processing, video encoding acceleration, and physics simulation. The 16.9% lead in Geekbench OpenCL suggests that applications relying heavily on this API will see measurable performance benefits on the AMD card.

The NVIDIA Quadro 2000D, despite losing the compute benchmark, belongs to the Quadro professional lineup. The database records it as part of the Quadro Fermi generation, a product family designed for professional graphics workstations. Its 2x DVI display outputs and single-slot form factor indicate a focus on multi-display professional setups. However, the recorded data does not include any professional application benchmarks such as SPECviewperf or CAD-specific tests, so any advantage in that domain cannot be quantified from the available information.

The AMD Radeon R8 M445DX is classified as an integrated graphics processor (IGP) in the Gem System Hybrid (Rx M400) generation. Its display outputs are described as "Portable Device Dependent," meaning it is intended for mobile platforms where the display connectivity is determined by the host laptop. This positions it for portable computing scenarios rather than fixed workstations.

Architecture Differences

The architectural gap between these two GPUs is substantial. The NVIDIA Quadro 2000D uses the GF106 chip built on the Fermi architecture, produced on a 40 nm process at TSMC. The AMD Radeon R8 M445DX uses the Meso chip based on the GCN 3.0 architecture, also produced at TSMC but on a newer 28 nm process.

Transistor counts and die sizes tell a revealing story. The NVIDIA chip packs 1,170 million transistors into a 238 mm² die, yielding a transistor density of 4.9 million transistors per square millimeter. The AMD chip contains 1,550 million transistors on a much smaller 125 mm² die, achieving 12.4 million transistors per square millimeter. The AMD part is denser by a wide margin, more than doubling the transistor density of the Fermi chip.

The compute resources differ significantly in configuration. The NVIDIA Quadro 2000D has 192 shading units, 32 texture mapping units, and 16 ROPs. The AMD Radeon R8 M445DX has 320 shading units, 20 TMUs, and only 8 ROPs. The AMD card has 66.7% more shading units, but the NVIDIA card has 60% more TMUs and double the ROP count.

Memory architecture creates another fundamental divide. The NVIDIA Quadro 2000D uses dedicated 1024 MB of GDDR5 memory on a 128-bit bus, delivering 41.60 GB/s of bandwidth. The AMD Radeon R8 M445DX relies on system shared memory, with its bandwidth described as "System Dependent." This means the AMD card has no dedicated VRAM and must share the host system's memory, which is typical for integrated graphics solutions.

Clock behavior also differs. The NVIDIA card lists a memory clock of 650 MHz (2.6 Gbps effective) but no base or boost clock for the core. The AMD card has a base clock of 780 MHz and a boost clock of 1021 MHz, allowing dynamic frequency scaling under load.

Feature support shows the AMD card as more modern in API terms. The NVIDIA Quadro 2000D supports DirectX 12 (11_0), OpenGL 4.6, and has no Vulkan support listed. The AMD Radeon R8 M445DX supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the only head-to-head comparison available between these two GPUs. The AMD Radeon R8 M445DX scores 4727, while the NVIDIA Quadro 2000D scores 3930. The delta of 16.9% in favor of AMD is the defining performance metric in this comparison.

Putting these scores into context with their nearest rivals clarifies the competitive positioning. The NVIDIA Quadro 2000D at 3930 is within 0.3% of the NVIDIA Quadro K2000D (3919), essentially a statistical tie. It trails the NVIDIA GeForce GT 745M (3953) by 0.6%, the AMD Radeon R5 M420 (3956) by 0.7%, and the NVIDIA GeForce 830M (3957) by 0.7%. These are all extremely close margins, indicating the Quadro 2000D sits in a tightly packed performance cluster.

The AMD Radeon R8 M445DX at 4727 leads the NVIDIA Quadro P400 (4684) by 0.9%. It trails the AMD Radeon R5 M335 (4752) by 0.5%, the AMD Radeon R5 M255 (4788) by 1.3%, and the NVIDIA GeForce RTX 3080 12 GB (4791) by 1.3%. The appearance of the RTX 3080 12 GB in this rival list is notable, though the score suggests the comparison is based on this specific OpenCL workload rather than overall gaming performance.

The measured 16.9% gap between the two comparison subjects is far larger than any delta among their respective nearest rivals. This suggests the AMD card occupies a clearly higher performance tier in OpenCL compute than the NVIDIA card, despite both being end-of-life products.

The Verdict

The data supports a straightforward conclusion: the AMD Radeon R8 M445DX is the faster GPU in OpenCL compute performance, with a 16.9% lead over the NVIDIA Quadro 2000D. The AMD card also reaches a higher percentile ranking (27th versus 23rd) among all GPUs in the database.

For users whose workloads depend on OpenCL acceleration, the AMD Radeon R8 M445DX is the clear choice from this data. Its 320 shading units and 653.4 GFLOPS of FP32 performance, combined with its 653.4 GFLOPS FP16 throughput (at a 1:1 ratio), provide the compute headroom that drives its higher benchmark score. The NVIDIA Quadro 2000D delivers 480.0 GFLOPS of FP32 performance, which is 26.5% lower than the AMD card's figure.

The NVIDIA Quadro 2000D retains relevance only for scenarios where its specific professional features matter. It has a 62 W TDP, a single-slot design, and two DVI outputs. It launches with a 599 USD MSRP, which places it in the professional graphics tier. Its Fermi architecture lacks Vulkan support, which limits modern API compatibility.

The AMD Radeon R8 M445DX is an integrated part with system shared memory, meaning its performance in memory-bound workloads will depend on the host system's memory configuration. Its 8 ROPs are few, and its pixel rate of 8.168 GPixel/s compares to 5.000 GPixel/s for the NVIDIA card. The AMD card has a higher texture rate at 20.42 GTexel/s versus 20.00 GTexel/s for NVIDIA, a marginal difference.

For a desktop workstation with dedicated memory requirements and professional display outputs, the NVIDIA Quadro 2000D offers a defined hardware configuration. For raw compute performance in OpenCL and modern API support including Vulkan, the AMD Radeon R8 M445DX is the better performer according to the recorded measurements.
