AMD Radeon 840M vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

The Verdict

The AMD Radeon 840M and NVIDIA RTX PRO 6000 Blackwell Server occupy opposite ends of the GPU spectrum, and the recorded data makes that distinction clear. The Radeon 840M is an integrated graphics processor (IGP) built into the Krackan Point chip, designed for portable devices where the display outputs are dependent on the host laptop or mini PC. It carries a 15 W thermal design power, uses system shared memory, and connects through PCIe 4.0 x8. The RTX PRO 6000 Blackwell Server is a dual-slot add-in card with a 600 W TDP, 96 GB of dedicated GDDR7 memory on a 512-bit bus, and a PCIe 5.0 x16 interface. These are not competing products in any practical sense, but the benchmark data allows for a direct comparison of their raw capabilities.

The database shows the RTX PRO 6000 Blackwell Server with a 3DMark Steel Nomad DX12 score of 5996, placing it at the 34th percentile of all GPUs. Its nearest rivals in the database are the GeForce GTX 770M at 6000 (0.1% ahead), the Radeon RX 6400 at 6001 (0.1% ahead), the FirePro W4100 at 5987 (0.2% behind), and the Quadro K4000M at 5986 (0.2% behind). The Radeon 840M has no recorded benchmark scores and no nearest rivals in the database, so its performance cannot be quantified from the available data. The verdict is straightforward: the RTX PRO 6000 Blackwell Server is a professional workstation or server GPU with measurable performance, while the Radeon 840M is an integrated solution meant for light, everyday graphics tasks in portable systems. Anyone needing dedicated compute, large memory capacity, or server-class features should choose the NVIDIA card. Anyone building an ultra-portable device with minimal power draw and no room for a discrete GPU should consider the AMD IGP.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm TSMC process, part of the Navi III IGP generation for Strix Point Mobile. Its chip is Krackan Point, and it succeeds the Navi II IGP. The NVIDIA RTX PRO 6000 Blackwell Server uses the Blackwell 2.0 architecture on a 5 nm TSMC process, part of the Server Blackwell (Bxx) generation. Its chip is GB202, with 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9 million per mm². The Radeon 840M's transistor count and die size are listed as unknown in the database.

Core counts differ dramatically. The Radeon 840M has 256 shading units, 16 texture mapping units, 8 raster operation units, and 4 ray tracing cores. It has no tensor cores listed. The RTX PRO 6000 Blackwell Server has 24,064 shading units, 752 TMUs, 192 ROPs, 188 ray tracing cores, and 752 tensor cores. The NVIDIA part also supports a wider API set, though both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon 840M has no tensor cores, which means it lacks the dedicated AI acceleration hardware that the RTX PRO 6000 provides.

Memory architecture is fundamentally different. The Radeon 840M uses system shared memory, with a system dependent bandwidth and no dedicated VRAM. The RTX PRO 6000 has 96 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s of bandwidth. Clock speeds also differ: the AMD part runs at a 400 MHz base and 2900 MHz boost, while the NVIDIA part runs at 1590 MHz base and 2617 MHz boost. The RTX PRO 6000's memory clock is listed at 1750 MHz with 28 Gbps effective speed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Radeon 840M and the RTX PRO 6000 Blackwell Server. The only benchmark score recorded for either part is the RTX PRO 6000's 3DMark Steel Nomad DX12 result of 5996. That score places it at the 34th percentile of all GPUs in the database. Its nearest rivals in the database show a tight cluster: the GeForce GTX 770M scores 6000, which is 0.1% higher than the RTX PRO 6000. The Radeon RX 6400 also scores 6001, another 0.1% advantage. On the lower side, the FirePro W4100 scores 5987, which is 0.2% behind, and the Quadro K4000M scores 5986, also 0.2% behind. These deltas are negligible, indicating that the RTX PRO 6000's benchmark result falls within a narrow band of similar-scoring GPUs.

The Radeon 840M has no recorded benchmark scores, so there is no numerical basis for comparing its performance to the RTX PRO 6000 in any test. The average benchmark score for the Radeon 840M is 0, and its percentile versus all GPUs is 50, which reflects the absence of data rather than a measured performance level. For the RTX PRO 6000, the average benchmark score is 5996, matching its sole Steel Nomad result. Wins are recorded as 0 for both parts in the head-to-head section, which is consistent with the lack of paired test data.

Where Each One Wins

The RTX PRO 6000 Blackwell Server wins on every measurable specification in the database. Its FP32 throughput of 126.0 TFLOPS dwarfs the Radeon 840M's 1,484.8 GFLOPS, a difference of roughly 85 times. Texture rate follows the same pattern: 1,968.0 GTexel/s versus 46.40 GTexel/s, and pixel rate is 502.5 GPixel/s versus 23.20 GPixel/s. The NVIDIA part has 188 ray tracing cores and 752 tensor cores, while the AMD part has 4 ray tracing cores and no tensor cores. For any workload involving ray tracing, AI inference, or high-throughput compute, the RTX PRO 6000 is the only viable option from this data.

The Radeon 840M wins on power efficiency and physical footprint. Its 15 W TDP is 40 times lower than the RTX PRO 6000's 600 W. It requires no power connectors, whereas the NVIDIA card needs a single 16-pin connector and a 1000 W power supply recommendation. The AMD part is an IGP with no slot width, meaning it fits into any portable device without occupying an expansion slot. The NVIDIA card is dual-slot with specific dimensions. The Radeon 840M also carries a higher boost clock at 2900 MHz versus 2617 MHz, though this does not translate into higher throughput given its far smaller core count.

Use-case separation is clear from the data. The Radeon 840M suits thin-and-light laptops and compact systems where the 15 W power draw and integrated form factor are advantages, and where the system shared memory approach is acceptable. The RTX PRO 6000 Blackwell Server targets server and professional workstation environments that require 96 GB of GDDR7 memory, 1.79 TB/s bandwidth, PCIe 5.0 connectivity, and the compute capacity of 24,064 shading units. The release dates are close, but the product categories are not. The AMD part replaces the Navi II IGP, while the NVIDIA part follows the Server Hopper generation and is succeeded by Server Rubin. The benchmark data confirms that the RTX PRO 6000 delivers a measurable 3DMark Steel Nomad score, while the Radeon 840M has no recorded performance numbers in the database, leaving its capabilities to be inferred from its specifications alone.
