AMD Radeon 820M vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

The Verdict

The AMD Radeon 820M and NVIDIA RTX PRO 6000 Blackwell Server occupy opposite ends of the GPU spectrum, and the data reflects this clearly. The Radeon 820M is an integrated graphics processor (IGP) built into the Krackan Point 2 chip, designed for mobile and low-power systems. It carries a 15 W thermal design power (TDP), uses system-shared memory, and delivers 716.8 GFLOPS of FP32 compute. The RTX PRO 6000 Blackwell Server is a dual-slot, 600 W discrete server accelerator with 96 GB of dedicated GDDR7 memory, 126.0 TFLOPS of FP32 compute, and a 1.79 TB/s memory bandwidth.

The recorded benchmark data shows only one entry for the RTX PRO 6000 Blackwell Server: a 3DMark Steel Nomad DX12 score of 5996. The Radeon 820M has no benchmark scores recorded in the database. The RTX PRO 6000 sits at the 34th percentile among all GPUs in the database, with its nearest rivals being the NVIDIA GeForce GTX 770M (avg score 6000, delta -0.1%), AMD Radeon RX 6400 (avg score 6001, delta -0.1%), AMD FirePro W4100 (avg score 5987, delta 0.2%), and NVIDIA Quadro K4000M (avg score 5986, delta 0.2%). This places the RTX PRO 6000's measured performance in this specific test roughly on par with those older and much smaller cards, all within a 0.2% margin.

For the AMD Radeon 820M, the data supports a clear role: it is for systems where power consumption is the primary constraint and where the GPU must share system memory. It is a functional IGP for basic display output and light workloads. The RTX PRO 6000 Blackwell Server, by contrast, is for server environments requiring massive memory capacity (96 GB), high bandwidth (1.79 TB/s), and extensive compute resources (24,064 shading units, 188 RT cores, 752 tensor cores). The choice depends entirely on whether the workload needs the server-class resources or whether a low-power integrated solution suffices.

Architecture Differences

The two GPUs use fundamentally different architectures and manufacturing processes. The AMD Radeon 820M is built on the RDNA 3.5 architecture, using a 4 nm process at TSMC. It belongs to the Navi III IGP generation, specifically the Strix Point Mobile family. The chip is Krackan Point 2. Its base clock is 400 MHz with a boost clock of 2800 MHz. The NVIDIA RTX PRO 6000 Blackwell Server uses the Blackwell 2.0 architecture on a 5 nm TSMC process, with the GB202 chip. It belongs to the Server Blackwell (Bxx) generation. Its base clock is 1590 MHz and boost clock is 2617 MHz. The RTX PRO 6000 has 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9M per mm². The Radeon 820M's transistor count and die size are listed as unknown.

The compute resources differ by orders of magnitude. The Radeon 820M has 128 shading units, 8 texture mapping units (TMUs), 4 render output units (ROPs), and 2 ray tracing cores. The RTX PRO 6000 has 24,064 shading units, 752 TMUs, 192 ROPs, 188 RT cores, and 752 tensor cores. The Radeon 820M has no tensor cores listed. The pixel rate for the Radeon 820M is 11.20 GPixel/s, versus 502.5 GPixel/s for the RTX PRO 6000. Texture rates are 22.40 GTexel/s and 1,968.0 GTexel/s respectively. FP32 performance is 716.8 GFLOPS for the AMD part and 126.0 TFLOPS for the NVIDIA part, both with a 1:1 FP16 ratio.

Memory architecture is another clear separator. The Radeon 820M uses System Shared memory, with a System Shared bus width and System Dependent bandwidth. The RTX PRO 6000 uses 96 GB of GDDR7 on a 512-bit bus, with 1.79 TB/s of bandwidth. The memory clock for the NVIDIA part is 1750 MHz, rated at 28 Gbps effective. The Radeon 820M's memory clock is also listed as System Shared.

The bus interfaces differ as well. The Radeon 820M uses PCIe 4.0 x8, while the RTX PRO 6000 uses PCIe 5.0 x16. The power delivery reflects the performance gap: the Radeon 820M has a 15 W TDP with no power connectors, while the RTX PRO 6000 has a 600 W TDP, requires a single 16-pin power connector, and a suggested power supply of 1000 W. The Radeon 820M is an IGP with slot width listed as IGP, while the RTX PRO 6000 is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width. Display outputs are Portable Device Dependent for the AMD part and 4x DisplayPort 2.1b for the NVIDIA part.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active in production status. The Radeon 820M was released on 2025-02-28, and its predecessor is Navi II IGP. The RTX PRO 6000 was released on 2025-03-17, with its predecessor being Server Hopper and its successor Server Rubin.

Where Each One Wins

The Radeon 820M wins in power efficiency and integration. Its 15 W TDP is minimal, it requires no external power connectors, and it uses system memory, which means no dedicated VRAM purchase is needed. The data shows it is built for portable devices, as its display outputs are portable device dependent. The base clock of 400 MHz and boost of 2800 MHz are modest, but the architecture supports modern APIs. For systems where the CPU and GPU share the same die and power budget, this is the only sensible choice.

The RTX PRO 6000 Blackwell Server wins in every performance metric recorded. Its compute capacity is vastly higher: 126.0 TFLOPS FP32 versus 716.8 GFLOPS for the Radeon 820M. The memory system is dedicated and high-bandwidth: 1.79 TB/s versus system-dependent bandwidth for the AMD part. With 96 GB of GDDR7, it can hold datasets that would not fit in system-shared memory. The 752 tensor cores provide AI acceleration capability that the Radeon 820M lacks entirely.

The benchmark data for the RTX PRO 6000 shows a 3DMark Steel Nomad DX12 score of 5996, which places it at the 34th percentile among all GPUs. The nearest rival comparisons put it within 0.2% of the GeForce GTX 770M, Radeon RX 6400, FirePro W4100, and Quadro K4000M in this specific test. That is a narrow band: the deltas are -0.1%, -0.1%, 0.2%, and 0.2% respectively. This indicates that in this particular workload, the RTX PRO 6000 does not pull ahead of those older cards by a meaningful margin, despite its massive hardware specifications. The Radeon 820M has no benchmark scores, so no direct comparison can be made from recorded data.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Radeon 820M and the RTX PRO 6000 Blackwell Server. The Radeon 820M has zero recorded benchmark scores. The RTX PRO 6000 has a single benchmark entry: 5996 in 3DMark Steel Nomad DX12.

That score of 5996 is the only measured performance data point available for either product. The RTX PRO 6000's nearest rivals in the database are all older or lower-tier cards. The GeForce GTX 770M averages 6000, which is 0.1% higher than the RTX PRO 6000's score. The Radeon RX 6400 averages 6001, also 0.1% higher. The FirePro W4100 averages 5987, which is 0.2% lower. The Quadro K4000M averages 5986, 0.2% lower. The RTX PRO 6000 sits essentially at parity with these four cards in this specific DX12 workload, despite having vastly more shading units, memory, and bandwidth. The 34th percentile ranking among all GPUs confirms this middling position in this test.

The Radeon 820M cannot be compared in the same way because it has no recorded scores. Its theoretical specifications, such as 11.20 GPixel/s pixel rate and 22.40 GTexel/s texture rate, are far below the RTX PRO 6000's 502.5 GPixel/s and 1,968.0 GTexel/s. The FP32 figures are similarly lopsided: 716.8 GFLOPS versus 126.0 TFLOPS. These are compute-rate differences, not measured benchmark outcomes, but they indicate the performance envelope for each part.

The RTX PRO 6000's 188 RT cores and 752 tensor cores provide capabilities that the Radeon 820M lacks. The Radeon 820M has 2 RT cores and no tensor cores listed. For workloads that use these units, the RTX PRO 6000 has dedicated hardware, while the Radeon 820M does not. The memory bandwidth difference is also stark: 1.79 TB/s versus System Dependent bandwidth for the AMD part. In memory-bound tasks, the RTX PRO 6000 has a clear structural advantage.
