AMD Radeon 840M vs NVIDIA GeForce RTX 5090 D V2 Comparison

Head-to-Head Benchmarks

The data shows a decisive overall win for the NVIDIA GeForce RTX 5090 D V2, though the comparison is unusual: the AMD Radeon 840M has no individual benchmark records in the database, while the RTX 5090 D V2 has one recorded result. That benchmark, 3DMark Steel Nomad DX12, returns a score of 16,504. The Radeon 840M carries an average benchmark score of 0, meaning no comparable measurement exists for it. Consequently, the head-to-head win count stands at 0 for the AMD part and 1 for the NVIDIA part.

The RTX 5090 D V2’s recorded score places it at the 59th percentile among all GPUs in the database, which indicates it sits slightly above the midpoint of the entire performance distribution. Its nearest rivals reinforce this positioning: the NVIDIA T400 scores 16,508 (a delta of 0%), the AMD Radeon PRO W7500 scores 16,415 (0.5% slower), the NVIDIA RTX PRO 6000 Blackwell scores 16,408 (0.6% slower), and the AMD Radeon RX 5700 XT scores 16,361 (0.9% slower). The RTX 5090 D V2 is therefore effectively tied with the T400, and only marginally ahead of the other three, despite being a far larger and more power-hungry part.

Because the Radeon 840M has no benchmark entries, the database cannot produce a direct numerical comparison between the two. The only quantitative story is the RTX 5090 D V2’s single result and its narrow lead over its closest recorded competitors. The AMD part’s percentile rank of 50 is a default value, not a measured performance figure, so it should not be read as evidence of parity with the NVIDIA card.

Where Each One Wins

The RTX 5090 D V2 wins on every measurable axis in the database. Its 3DMark Steel Nomad DX12 score of 16,504 is the sole benchmark data point, and it outperforms all four nearest rivals by margins ranging from 0% to 0.9%. That narrow spread suggests the card is positioned at a specific performance tier in the database, not at the top of the overall rankings.

The Radeon 840M wins in no benchmark category, as it has no recorded scores. However, the data does show distinct usage domains based on hardware characteristics. The RTX 5090 D V2 is designed for discrete, high-throughput workloads: it carries 24 GB of GDDR7 memory on a 384-bit bus with 1.34 TB/s of bandwidth, making it suited for large datasets and memory-intensive rendering. The Radeon 840M is an integrated graphics processor (IGP) with system-shared memory, meaning its bandwidth is system dependent and its memory pool is whatever the host system provides. That makes it inherently limited to lighter workloads, such as basic display output or low-complexity 2D tasks, though its specifications do include ray tracing cores and DirectX 12 Ultimate support.

The use-case split is therefore stark: the RTX 5090 D V2 is for demanding 3D workloads, while the Radeon 840M is for systems where discrete graphics are not present and power consumption must stay minimal. The RTX 5090 D V2 has a TDP of 575 W and requires a 950 W suggested PSU, while the Radeon 840M has a TDP of 15 W and no power connectors. The former is a dual-slot card 304 mm long, 137 mm high, and 48 mm wide; the latter is an IGP with no slot width, length, or height listed.

Architecture Differences

The two GPUs come from entirely different architectural generations and design philosophies. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm process node at TSMC, with the chip codenamed Krackan Point. It belongs to the Navi III IGP (Strix Point Mobile) generation. The NVIDIA GeForce RTX 5090 D V2 uses the Blackwell 2.0 architecture on a 5 nm process node, also at TSMC, with the GB202 chip, part of the GeForce 50 generation.

The transistor counts are not directly comparable because the AMD part’s transistor count and die size are listed as unknown. The NVIDIA chip contains 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per mm². The Radeon 840M’s density is not recorded.

Compute resources differ by an order of magnitude. The Radeon 840M has 256 shading units, 16 texture mapping units, 8 ROPs, and 4 ray tracing cores. The RTX 5090 D V2 has 21,760 shading units, 680 TMUs, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. The NVIDIA card’s pixel rate is 423.6 GPixel/s and texture rate is 1,636.8 GTexel/s, while the AMD part’s rates are 23.20 GPixel/s and 46.40 GTexel/s. FP32 and FP16 compute are both 104.8 TFLOPS on the NVIDIA card (1:1 ratio), while the AMD IGP delivers 1,484.8 GFLOPS in both FP32 and FP16 (also 1:1). In raw throughput, the RTX 5090 D V2 is roughly 70 times higher in FP32, though the database does not provide a direct percentage comparison.

Clock behavior also diverges. The Radeon 840M’s base clock is 400 MHz with a boost of 2900 MHz. The RTX 5090 D V2 has a base clock of 2017 MHz and a boost of 2407 MHz, with memory clocked at 1750 MHz (28 Gbps effective). The AMD part’s memory clock is listed as system shared, meaning it depends on the host system’s RAM.

Both support identical API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active in production status.

Specification Differences

The most significant specification gap is memory. The Radeon 840M uses system-shared memory with no dedicated size, type, bus width, or bandwidth; all are system dependent. The RTX 5090 D V2 has 24 GB of GDDR7 on a 384-bit bus with 1.34 TB/s bandwidth. This is a fundamental difference: the NVIDIA card’s memory subsystem is fixed and high-bandwidth, while the AMD IGP’s performance varies with the host system’s memory configuration.

Power requirements are equally divergent. The Radeon 840M has a TDP of 15 W, no power connectors, and no suggested PSU. The RTX 5090 D V2 has a TDP of 575 W, one 16-pin power connector, and a suggested PSU of 950 W. The slot width differs: the AMD part is an IGP with no slot width, while the NVIDIA part is dual-slot.

The bus interface differs: the Radeon 840M uses PCIe 4.0 x8, the RTX 5090 D V2 uses PCIe 5.0 x16. Display outputs also differ: the AMD IGP’s outputs are portable device dependent, while the NVIDIA card provides 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Physical dimensions are only recorded for the NVIDIA card: 304 mm (12 inches) long, 137 mm (5.4 inches) high, and 48 mm (1.9 inches) wide. The AMD IGP has no dimensions listed.

Release dates differ by several months: the Radeon 840M launched on 2025-02-28, and the RTX 5090 D V2 on 2025-08-14. The predecessor and successor fields also differ: the AMD part’s predecessor is Navi II IGP, while the NVIDIA card’s predecessor is GeForce 40 and its successor is GeForce 60. The NVIDIA card has a launch MSRP of 2,299 USD; the AMD part has no recorded launch MSRP.

The Verdict

The data supports one clear conclusion: the RTX 5090 D V2 is a high-performance discrete GPU with a measured benchmark score, while the Radeon 840M is an integrated part with no recorded performance data. Anyone needing the recorded 3DMark Steel Nomad DX12 result of 16,504 and the associated 59th percentile placement should select the NVIDIA card. Its 24 GB GDDR7 memory, 1.34 TB/s bandwidth, 21,760 shading units, and 575 W TDP define it as a workstation or enthusiast-class part, though its nearest rivals in the database are all within 0.9% of its score, indicating that its performance tier is not uniquely dominant.

The Radeon 840M is suitable for systems where discrete graphics are absent. Its 15 W TDP, lack of power connectors, and system-shared memory make it appropriate for portable or low-power devices, but its complete absence of benchmark records means no performance claims can be made from the database. Its 256 shading units, 4 ray tracing cores, and 1,484.8 GFLOPS FP32 throughput are the only quantitative measures available, and they are far below the RTX 5090 D V2’s figures.

The verdict is straightforward: the RTX 5090 D V2 is the only part with measurable performance in this comparison, and it wins the sole benchmark by definition. The Radeon 840M cannot be recommended for any workload that requires the recorded performance tier, as no evidence exists for its capabilities. For systems with no discrete GPU slot, the Radeon 840M exists as an IGP option, but the database provides no basis for ranking it against any discrete card, including the RTX 5090 D V2. The NVIDIA part’s launch MSRP of 2,299 USD and its active production status confirm its positioning as a current, high-end offering, while the AMD part’s active status and 2025-02-28 release date place it as a recent integrated solution.
