AMD Radeon HD 8970M vs NVIDIA Quadro K5200 Comparison

The AMD Radeon HD 8970M and NVIDIA Quadro K5200 represent two distinct approaches to mobile and workstation graphics from the same era. The data shows a single head-to-head benchmark result, but the specifications reveal significant architectural and design philosophy differences that go far beyond that one score. The HD 8970M, a mobile part built on GCN 1.0, squares off against the K5200, a dual-slot workstation card built on Kepler, with each optimized for very different priorities.

Head-to-Head Benchmarks

The only direct benchmark comparison available is the Geekbench OpenCL test, and the result is a decisive win for the AMD Radeon HD 8970M. In this test, the HD 8970M scores 21237, while the NVIDIA Quadro K5200 scores 19024. This gives AMD an 11.6% advantage over the K5200 in raw compute performance as measured by this specific workload. The delta is substantial, indicating that for OpenCL compute tasks, the mobile AMD part holds a clear edge over the older workstation NVIDIA card.

Looking at how each card compares to its own nearest rivals provides context for this head-to-head result. The HD 8970M’s score of 21237 places it just 0.4% ahead of the AMD Radeon RX Vega M GL (21153) and 1% ahead of the NVIDIA GeForce RTX 5050 (21035). It trails the NVIDIA RTX A4000 Mobile (21379) by 0.7% and the NVIDIA Quadro RTX 5000 (21629) by 1.8%. These are extremely tight margins, showing that the HD 8970M’s OpenCL performance is competitive with much newer hardware. The K5200, with its score of 19024, sits in a different performance tier. It is 0.2% behind the AMD FirePro D300 (19637) and 0.8% behind the AMD Radeon RX 6650 XT (19765), while being 1% ahead of the AMD Radeon RX 7900 XTX (19410) and 1.4% ahead of the NVIDIA GeForce GTX 1060 3 GB (19334).

The percentile rankings reinforce this gap. The HD 8970M sits in the 66th percentile of all GPUs, while the K5200 sits in the 64th percentile. While a two-percentile difference is not enormous, it aligns with the 11.6% delta in the direct comparison. The data suggests that the HD 8970M is not just marginally faster, but consistently positioned higher in the overall performance distribution. The K5200’s nearest rivals include a range of cards from different generations, and its position among them shows it holds its own against mid-range options but does not rival the peak performance of the HD 8970M in this compute test.

Architecture Differences

The fundamental architectural divide between these two GPUs is stark. The HD 8970M is built on AMD’s GCN 1.0 architecture, using the Neptune chip, while the K5200 uses NVIDIA’s Kepler architecture, built on the GK110B chip. Both are manufactured on a 28 nm process at TSMC, but the similarities end there. The Neptune chip packs 2,800 million transistors into a 212 mm² die, resulting in a transistor density of 13.2M per mm². The GK110B is a much larger and more complex chip, with 7,080 million transistors on a 561 mm² die, giving it a slightly lower density of 12.6M per mm². This size difference reflects a different design strategy: AMD’s chip is smaller and more power-efficient per square millimeter, while NVIDIA’s is larger and more feature-rich.

The memory subsystems also differ notably. The HD 8970M comes with 4 GB of GDDR5 memory on a 256-bit bus, delivering 153.6 GB/s of bandwidth. The K5200 doubles the capacity to 8 GB on the same 256-bit bus, but uses faster 6 Gbps effective memory to achieve 192.3 GB/s of bandwidth. This gives the K5200 a 25% bandwidth advantage, which is significant for large datasets common in professional workloads.

Compute resources are where the architectural philosophies diverge most clearly. The HD 8970M has 1280 shading units, 80 texture mapping units, and 32 render output units. The K5200 has 2304 shading units, 192 TMUs, and 48 ROPs. These are massive differences: the K5200 has 80% more shaders, 140% more TMUs, and 50% more ROPs. However, the HD 8970M compensates with much higher clock speeds. Its base clock is 850 MHz and boost clock is 900 MHz, while the K5200 runs at a base of 667 MHz and boost of 771 MHz. The HD 8970M’s clocks are 27% higher at base and 17% higher at boost, which helps close the raw compute gap.

The result is that the K5200 still holds a commanding lead in peak throughput. Its pixel rate is 37.01 GPixel/s versus 28.80 GPixel/s for the HD 8970M, a 28% advantage. Its texture rate of 148.0 GTexel/s is more than double the HD 8970M’s 72.00 GTexel/s. In FP32 compute, the K5200 delivers 3.553 TFLOPS versus 2.304 TFLOPS for the HD 8970M, a 54% advantage. This is a case where the K5200’s sheer scale of execution units overcomes its lower clocks, but the OpenCL benchmark result tells a different story, suggesting that real-world compute efficiency and driver optimizations can favor the GCN architecture.

The Verdict

The data presents a clear but nuanced picture. For pure OpenCL compute performance, the AMD Radeon HD 8970M is the winner, posting an 11.6% higher score than the NVIDIA Quadro K5200. This is despite the K5200 having significantly more raw compute resources on paper. The HD 8970M’s higher clock speeds and GCN architecture appear to translate more efficiently into benchmark results in this specific test.

However, the K5200 is not without its strengths. It offers double the memory capacity at 8 GB, higher memory bandwidth, and a much higher peak FP32 throughput. For workloads that are memory-bound or that can fully utilize the K5200’s 2304 shading units, the NVIDIA card would likely be the better choice. The K5200 is also a dual-slot card with a 150 W TDP and a 450 W suggested PSU, while the HD 8970M is an MXM module with a 100 W TDP, indicating they target completely different form factors and use cases.

The HD 8970M is a mobile-first solution, designed for laptops where power and space are constrained. Its 100 W TDP and MXM module form factor make it suitable for high-end gaming laptops of its era. The K5200 is a workstation card, designed for desktop professional systems. Its dual-slot design, 267 mm length, and display outputs of 2x DVI and 2x DisplayPort 1.2 are tailored for multi-monitor professional setups. Users who need a compute-focused mobile GPU should look to the HD 8970M, while those who need a workstation card with large memory capacity and high peak compute for professional applications should consider the K5200, despite its lower OpenCL score.

Specification Differences

The two cards differ across nearly every major specification category. The process node is identical at 28 nm, and both use TSMC as the foundry, but the chips are fundamentally different. The HD 8970M uses the Neptune chip with 2,800 million transistors on a 212 mm² die, while the K5200 uses the GK110B with 7,080 million transistors on a 561 mm² die. Transistor density is 13.2M / mm² for AMD versus 12.6M / mm² for NVIDIA.

Clock speeds differ substantially. The HD 8970M has a base clock of 850 MHz and a boost clock of 900 MHz, while the K5200 runs at 667 MHz base and 771 MHz boost. Memory clocks also differ, with the HD 8970M at 1200 MHz (4.8 Gbps effective) and the K5200 at 1502 MHz (6 Gbps effective). Memory capacity is 4 GB for the HD 8970M versus 8 GB for the K5200, though both use GDDR5 on a 256-bit bus. Bandwidth is 153.6 GB/s for AMD and 192.3 GB/s for NVIDIA.

Compute unit counts are dramatically different. The HD 8970M has 1280 shading units, 80 TMUs, and 32 ROPs. The K5200 has 2304 shading units, 192 TMUs, and 48 ROPs. Pixel rate is 28.80 GPixel/s for AMD versus 37.01 GPixel/s for NVIDIA. Texture rate is 72.00 GTexel/s versus 148.0 GTexel/s. FP32 performance is 2.304 TFLOPS versus 3.553 TFLOPS. Power consumption is 100 W for the HD 8970M and 150 W for the K5200.

The form factors are entirely different. The HD 8970M is an MXM Module, while the K5200 is a Dual-slot card measuring 267 mm in length and 111 mm in height. The K5200 requires a 1x 6-pin power connector and a 450 W suggested PSU, while the HD 8970M lists no power connectors. Display outputs are "Portable Device Dependent" for the AMD card, while the NVIDIA card offers 2x DVI and 2x DisplayPort 1.2. Both support PCIe 3.0 x16. The APIs are similar, with both supporting DirectX 12 (11_1) and OpenGL 4.6, but the Vulkan support differs slightly: the HD 8970M supports Vulkan 1.2.170, while the K5200 supports Vulkan 1.2.175.
