AMD Radeon 840M vs NVIDIA RTX PRO 6000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded database contains a single benchmark result for the NVIDIA RTX PRO 6000 Blackwell, while the AMD Radeon 840M has no benchmark entries. This asymmetry makes a direct numerical comparison of measured performance impossible. The RTX PRO 6000 Blackwell scored 16,408 points in the 3DMark Steel Nomad DX12 test, placing it in the 59th percentile of all GPUs tracked in the database.

The RTX PRO 6000 Blackwell sits within a tightly clustered group of rivals in the database. Its score of 16,408 is effectively tied with the AMD Radeon PRO W7500, which averaged 16,415 points, a delta of 0 percent. The NVIDIA card also edges out the AMD Radeon RX 5700 XT, which scored 16,361, by 0.3 percent. Against the AMD Radeon Pro 5600M at 16,351, the RTX PRO 6000 Blackwell holds a 0.4 percent advantage. The only competitor ahead in this group is the NVIDIA GeForce RTX 5090 D V2 at 16,504, which leads by 0.6 percent.

The AMD Radeon 840M has no recorded benchmark scores in the database, and its percentile ranking of 50 is a placeholder rather than a measured result. Its average benchmark score is listed as zero, confirming the absence of test data. Consequently, the head-to-head comparison shows zero wins for the AMD part and zero wins for the NVIDIA part, since no shared benchmark exists to adjudicate between them.

What the data does reveal is the raw specification gap between the two products. The RTX PRO 6000 Blackwell delivers 126.0 TFLOPS of FP32 compute, while the Radeon 840M is rated at 1,484.8 GFLOPS. The NVIDIA card's pixel rate of 502.5 GPixel/s and texture rate of 1,968.0 GTexel/s dwarf the AMD part's 23.20 GPixel/s and 46.40 GTexel/s. The memory subsystem tells a similar story: the RTX PRO 6000 Blackwell uses 96 GB of GDDR7 on a 512-bit bus with 1.79 TB/s of bandwidth, whereas the Radeon 840M relies on system-shared memory with bandwidth described only as system dependent.

The Verdict

The data shows two products designed for entirely different segments, and the specification sheet alone dictates the separation. The AMD Radeon 840M is an integrated graphics processor within the Krackan Point chip, rated at 15 W TDP, using the PCIe 4.0 x8 interface, and intended for portable devices where display output is dependent on the host system. The NVIDIA RTX PRO 6000 Blackwell is a dual-slot discrete workstation card with a 600 W TDP, a 1x 16-pin power connector, a recommended 1000 W power supply, and four DisplayPort 2.1b outputs.

For users whose workload requires the RTX PRO 6000 Blackwell's capabilities, the choice is straightforward from the recorded data. The 96 GB GDDR7 memory, 512-bit bus, and 1.79 TB/s bandwidth address large datasets that would overwhelm the system-shared memory of the Radeon 840M. The NVIDIA card's 24064 shading units, 752 tensor cores, and 188 RT cores provide compute resources that the AMD part cannot approach. The single recorded benchmark of 16,408 in 3DMark Steel Nomad confirms the NVIDIA card performs at a level within 0.6 percent of the GeForce RTX 5090 D V2 and ahead of the Radeon PRO W7500, RX 5700 XT, and Radeon Pro 5600M.

The AMD Radeon 840M, by contrast, has no benchmark data in the database. Its 15 W TDP and integrated nature place it in the mobile and low-power segment. The 4 nm process node and RDNA 3.5 architecture indicate a modern design, but the absence of measured performance means no empirical claim can be made about its real-world speed. The 256 shading units, 16 TMUs, and 8 ROPs are an order of magnitude below the NVIDIA part's 24064 shading units, 752 TMUs, and 192 ROPs.

The verdict from the data is unambiguous: the RTX PRO 6000 Blackwell is the only one of the two with recorded performance, and it delivers that performance at a level competitive with its nearest rivals. The Radeon 840M serves a different role, one where power consumption, integration, and portability matter more than raw throughput. Neither product is a substitute for the other.

Specification Differences

The two products differ across nearly every measurable specification. The process node differs: the AMD Radeon 840M uses TSMC's 4 nm process, while the NVIDIA RTX PRO 6000 Blackwell uses a 5 nm process, also from TSMC. The NVIDIA part discloses its transistor count at 92,200 million on a 750 mm² die, with a transistor density of 122.9M per mm². The AMD part lists its transistor count and die size as unknown.

Clock speeds show the AMD part with a 400 MHz base and 2900 MHz boost, while the NVIDIA card runs at 1590 MHz base and 2617 MHz boost. The memory clocks differ entirely: the Radeon 840M uses system-shared memory, while the RTX PRO 6000 Blackwell operates at 1750 MHz with 28 Gbps effective speed.

The compute resources are starkly different. The Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores, with no tensor cores listed. The RTX PRO 6000 Blackwell has 24064 shading units, 752 TMUs, 192 ROPs, 188 RT cores, and 752 tensor cores. The pixel rate is 23.20 GPixel/s versus 502.5 GPixel/s, and the texture rate is 46.40 GTexel/s versus 1,968.0 GTexel/s. FP32 performance is 1,484.8 GFLOPS versus 126.0 TFLOPS, with both operating at a 1:1 FP16 ratio.

The physical specifications diverge as well. The Radeon 840M is an IGP with no slot width, no power connectors, and a PCIe 4.0 x8 bus interface. The RTX PRO 6000 Blackwell is dual-slot, 304 mm long, 137 mm high, and 40 mm wide, using PCIe 5.0 x16 and a single 16-pin power connector. The NVIDIA card has four DisplayPort 2.1b outputs, while the AMD part's display outputs are portable device dependent. The RTX PRO 6000 Blackwell carries a launch MSRP of 8,565 USD; the Radeon 840M has no listed launch MSRP.

Architecture Differences

The architectural split between the two products is fundamental. The AMD Radeon 840M is built on RDNA 3.5, part of the Navi III IGP generation for Strix Point Mobile, and uses the Krackan Point chip. Its predecessor is listed as Navi II IGP. The NVIDIA RTX PRO 6000 Blackwell uses Blackwell 2.0 architecture on the GB202 chip, belongs to the Blackwell PRO W (x000) generation, and succeeds the Workstation Ada line.

The AMD part is a 4 nm integrated design with unknown transistor count and die size, reflecting its role as a mobile IGP within a larger processor package. The NVIDIA part is a 5 nm discrete GPU with 92,200 million transistors on a 750 mm² die, a density of 122.9M transistors per mm². The two chips share the same foundry, TSMC, but the process difference and die scale indicate very different design goals.

The RT core counts differ by a factor of 47: 4 RT cores on the AMD part versus 188 on the NVIDIA card. The Radeon 840M lacks tensor cores entirely, while the RTX PRO 6000 Blackwell includes 752. The shading unit ratio is roughly 94 to 1 in favor of NVIDIA. These differences reflect the RDNA 3.5 architecture's focus on integrated efficiency versus the Blackwell architecture's emphasis on workstation compute density.

The memory architecture is equally divergent. The Radeon 840M shares system memory with no dedicated VRAM, no dedicated bus width, and bandwidth dependent on the host system. The RTX PRO 6000 Blackwell has a dedicated 96 GB GDDR7 frame buffer on a 512-bit bus, achieving 1.79 TB/s of bandwidth. The release dates fall close together: the AMD part launched on February 28, 2025, and the NVIDIA card on March 17, 2025, but the architectural lineage and physical implementation could not be more different. The production status for both is listed as active.
