Architecture Differences

The AMD Radeon 820M uses the Krackan Point 2 chip built on TSMC's 4 nm process, belonging to the Navi III IGP generation. It implements the RDNA 3.5 architecture with 128 shading units, 8 texture mapping units, 4 raster operation pipelines, and 2 ray tracing cores. The GPU operates with a base clock of 400 MHz and a boost clock of 2800 MHz. Its transistor count and die size are not recorded in the database.

The NVIDIA RTX PRO 2000 Blackwell uses the GB206 chip fabricated on TSMC's 5 nm process, belonging to the Blackwell PRO W generation. It contains 21,900 million transistors on a 181 mm² die, yielding a transistor density of 121.0M per mm². The architecture includes 4352 shading units, 136 TMUs, 48 ROPs, 34 ray tracing cores, and 136 tensor cores. Its clocks run at 982 MHz base and 1957 MHz boost, with memory clocked at 1125 MHz or 18 Gbps effective.

The Radeon 820M has no dedicated tensor cores, relying entirely on its shader array for compute workloads. The RTX PRO 2000 Blackwell includes a substantial tensor core count, which supports AI-accelerated workflows. Both GPUs share identical API support profiles, including DirectX 12 Ultimate and Vulkan 1.4, so software compatibility does not differentiate them.

Pixel and texture throughput tell a clear story. The Radeon 820M produces 11.20 GPixel/s and 22.40 GTexel/s, while the RTX PRO 2000 Blackwell reaches 93.94 GPixel/s and 266.2 GTexel/s. The NVIDIA part also carries FP16 throughput at a 1:1 ratio with FP32, matching its 17.03 TFLOPS in both precisions; the AMD part likewise runs FP16 at 1:1 with FP32, capping at 716.8 GFLOPS.

The Radeon 820M is an IGP with no slot width, no power connectors, and a PCIe 4.0 x8 interface. The RTX PRO 2000 Blackwell is a dual-slot card measuring 167 mm in length, 69 mm in height, and 20 mm in width. It uses a PCIe 5.0 x8 interface and provides four mini-DisplayPort 2.1b outputs, while the AMD part's display outputs are described as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, so the comparison relies on the recorded scores for the NVIDIA RTX PRO 2000 Blackwell and its nearest rivals. The AMD Radeon 820M has no benchmark scores listed, and its percentile ranking sits at 50, which is below the NVIDIA part's 70th percentile placement.

The RTX PRO 2000 Blackwell's average benchmark score of 25269 places it in a competitive field. Its closest rival, the AMD Radeon RX 6700M, scores 25633, putting the NVIDIA card 1.4% behind. The AMD Radeon Pro W5700 scores 25726, a 1.8% advantage over the RTX PRO 2000. The NVIDIA GeForce RTX 3080 Ti Mobile also posts 25740, another 1.8% gap. The NVIDIA RTX A5000 Mobile scores 24763, which the RTX PRO 2000 beats by 2%.

These deltas indicate that the RTX PRO 2000 Blackwell sits in a tight performance cluster among mobile and workstation GPUs. The smallest deficit is 1.4% against the RX 6700M, while the largest lead is 2% over the RTX A5000 Mobile. The spread across all four rivals is only about 4 percentage points, suggesting that the RTX PRO 2000 occupies a well-defined performance tier rather than an outlier position.

Individual benchmark scores for the RTX PRO 2000 Blackwell show strong compute performance. The Geekbench Vulkan score of 113865 and OpenCL score of 106087 both indicate substantial throughput for GPU-accelerated workloads. The Passmark G3D score of 20049 confirms strong rasterization performance, while the Passmark GPU compute score of 8396 shows the card's capability in compute-oriented tasks.

The DirectX benchmark scores are notably lower in isolation, with Passmark DirectX 9 at 241, DirectX 10 at 122, DirectX 11 at 174, and DirectX 12 at 80. These figures likely reflect specific driver or workload characteristics rather than overall capability, given the high scores in other tests. The Passmark G2D score of 1303 indicates modest 2D performance relative to the 3D results.

Specification Differences

The two GPUs differ across nearly every measurable specification. The process nodes differ: the Radeon 820M uses 4 nm, while the RTX PRO 2000 uses 5 nm, both fabricated by TSMC. The AMD part's transistor count and die size are unknown, whereas the NVIDIA card records 21,900 million transistors on a 181 mm² die.

Clock speeds diverge significantly. The Radeon 820M has a 400 MHz base clock and a 2800 MHz boost clock. The RTX PRO 2000 runs at 982 MHz base and 1957 MHz boost. Despite lower absolute clocks, the NVIDIA card's much larger shader array delivers vastly higher throughput.

Memory configurations are entirely different. The Radeon 820M uses system shared memory with system-dependent bandwidth, while the RTX PRO 2000 has 16 GB of GDDR7 on a 128-bit bus with 288.0 GB/s bandwidth. The NVIDIA card's memory clock is 1125 MHz with 18 Gbps effective data rate.

Compute resources differ by an order of magnitude. The Radeon 820M has 128 shading units, 8 TMUs, 4 ROPs, and 2 ray tracing cores. The RTX PRO 2000 has 4352 shading units, 136 TMUs, 48 ROPs, 34 ray tracing cores, and 136 tensor cores. The AMD part has no tensor cores.

Rates and throughputs reflect the resource gap. Pixel rate is 11.20 GPixel/s for AMD versus 93.94 GPixel/s for NVIDIA. Texture rate is 22.40 GTexel/s versus 266.2 GTexel/s. FP32 compute is 716.8 GFLOPS versus 17.03 TFLOPS. FP16 matches FP32 on both at the same respective levels.

Power and physical specs diverge completely. The Radeon 820M has a 15 W TDP, an IGP slot width, no power connectors, and no suggested PSU. The RTX PRO 2000 has a 70 W TDP, dual-slot width, no power connectors, and a 250 W suggested PSU. The NVIDIA card measures 167 mm by 69 mm by 20 mm.

Bus interfaces and outputs differ. The Radeon 820M uses PCIe 4.0 x8 with portable device dependent outputs. The RTX PRO 2000 uses PCIe 5.0 x8 with four mini-DisplayPort 2.1b outputs. Release dates differ as well: the AMD part launched February 28, 2025, and the NVIDIA part launched August 10, 2025. Neither GPU has a recorded launch MSRP.

The Verdict

The benchmark data presents a clear hierarchy. The NVIDIA RTX PRO 2000 Blackwell holds a 70th percentile ranking among all GPUs with an average score of 25269, while the AMD Radeon 820M sits at the 50th percentile with no recorded benchmark scores. The NVIDIA card competes directly with established mobile and workstation GPUs, landing within 2% of the Radeon RX 6700M and RTX 3080 Ti Mobile, and 2% ahead of the RTX A5000 Mobile.

For workloads that demand dedicated graphics memory, the RTX PRO 2000 Blackwell is the only option with 16 GB of GDDR7 and 288.0 GB/s of bandwidth. The Radeon 820M relies on system shared memory, making its performance dependent on the host system's memory configuration. Applications that require sustained memory bandwidth or large working sets will favor the NVIDIA part.

Compute throughput also strongly favors the NVIDIA card. The 17.03 TFLOPS FP32 rating is roughly 24 times higher than the Radeon 820M's 716.8 GFLOPS. The inclusion of 136 tensor cores on the NVIDIA card provides hardware acceleration for AI workloads, which the AMD IGP cannot match due to its lack of tensor hardware. The RTX PRO 2000's ray tracing core count of 34 versus 2 further cements its advantage in ray-traced content.

The Radeon 820M's advantages are limited to integration and power. Its 15 W TDP suits thin-and-light portable devices, and its IGP form factor requires no expansion slot or additional cooling. The RTX PRO 2000's 70 W TDP and dual-slot footprint demand a larger chassis and a 250 W suggested PSU.

The database shows no scenario where the AMD part outperforms the NVIDIA card in recorded metrics. The RTX PRO 2000 Blackwell is the appropriate choice for workstation-class 3D rendering, GPU compute, and AI-accelerated tasks, based on its memory capacity, compute resources, and benchmark placement among similar products. The Radeon 820M serves integrated graphics duties in mobile systems where power efficiency and compactness take priority over raw performance.
