AMD Radeon 840M vs NVIDIA Jetson T5000 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Radeon 840M and the NVIDIA Jetson T5000. Neither part has any benchmark scores listed, and the wins tally is zero for both sides. As a result, direct performance comparisons must be inferred from the architectural and specification data rather than from measured test results.

The NVIDIA Jetson T5000 delivers 8.064 TFLOPS of FP32 compute, which is roughly 5.4 times the 1,484.8 GFLOPS of the AMD Radeon 840M. That gap is substantial in raw shader throughput. The Jetson T5000 also achieves a pixel rate of 50.40 GPixel/s against 23.20 GPixel/s for the Radeon, and a texture rate of 126.0 GTexel/s versus 46.40 GTexel/s. In every throughput metric recorded, the NVIDIA part leads by a wide margin.

The AMD Radeon 840M counters with a higher boost clock, 2900 MHz versus 1575 MHz for the Jetson T5000. The Radeon also uses a smaller 4 nm process node compared to the Jetson's 5 nm. Neither part shows any advantage in benchmark results because none exist in the database, so the analysis rests entirely on specifications.

The absence of measured data means the percentile ranking for both GPUs is identical at 50, and the average benchmark score for each is zero. Buyers should interpret the performance difference from the raw compute figures: the Jetson T5000 has 2,560 shading units against 256 for the Radeon, 80 texture mapping units against 16, and 32 render output units against 8. These are the numbers that define the performance envelope, not test scores.

Architecture Differences

The two GPUs come from different architectural generations and serve entirely different purposes. The AMD Radeon 840M uses the RDNA 3.5 architecture, built on a 4 nm process at TSMC, and belongs to the Navi III IGP generation for Strix Point Mobile. Its chip is called Krackan Point. The NVIDIA Jetson T5000 uses the Blackwell architecture on a 5 nm process at TSMC, belongs to the Server Blackwell generation, and its chip is designated GB10B.

Ray tracing hardware differs significantly. The Radeon 840M has 4 RT cores, while the Jetson T5000 has 20 RT cores. Tensor core counts also diverge: the Jetson T5000 has 96 tensor cores, and the Radeon 840M lists no tensor cores at all. That makes the NVIDIA part the clear choice for any workload relying on tensor operations.

Memory architecture is fundamentally different. The Radeon 840M uses system shared memory with system dependent bandwidth, meaning its performance scales with the host platform's memory subsystem. The Jetson T5000 has 128 GB of dedicated LPDDR5X memory on a 256 bit bus, delivering 273.2 GB/s of bandwidth. The memory clock is listed at 1067 MHz with 8.5 Gbps effective speed for the NVIDIA part, while the Radeon's memory clock is described simply as "System Shared."

API support separates the two completely. The Radeon 840M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Jetson T5000 lists N/A for DirectX, OpenGL, and Vulkan. That indicates the NVIDIA part is not designed for conventional graphics API workloads in the same way as the Radeon.

The process node advantage goes to AMD at 4 nm versus 5 nm, but the die size tells a different story. The Jetson T5000 has a die size of 391 mm², while the Radeon 840M's die size is unknown. Transistor counts are unknown for both.

The Verdict

The data indicates these are not competing products in the conventional sense. The AMD Radeon 840M is an integrated graphics processor for mobile devices, drawing 15 W and relying on system shared memory. The NVIDIA Jetson T5000 is a server-oriented Blackwell part with 128 GB of dedicated memory, 120 W TDP, and no display outputs.

For raw compute, the Jetson T5000 is dominant. Its FP32 throughput of 8.064 TFLOPS is more than five times the Radeon's 1,484.8 GFLOPS. Its texture rate of 126.0 GTexel/s is nearly triple the Radeon's 46.40 GTexel/s. Its pixel rate of 50.40 GPixel/s more than doubles the Radeon's 23.20 GPixel/s.

The Radeon 840M has advantages in clock speed, process node, and API compatibility. Its 2900 MHz boost clock is nearly double the Jetson's 1575 MHz. Its 4 nm process is smaller than the Jetson's 5 nm. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the Jetson lists no graphics APIs.

The Jetson T5000 is the only option for tensor workloads with its 96 tensor cores. The Radeon has no tensor cores listed. The Jetson also offers 20 RT cores versus 4 for the Radeon.

The launch MSRP for the Jetson T5000 is 2,999 USD. The Radeon has no launch MSRP recorded.

Where Each One Wins

The NVIDIA Jetson T5000 wins in every compute-heavy category. Its FP32 performance of 8.064 TFLOPS makes it suitable for server workloads where raw shader throughput matters. Its 273.2 GB/s memory bandwidth from 128 GB of LPDDR5X on a 256 bit bus provides far more memory capacity and bandwidth than the Radeon's system shared configuration. The 96 tensor cores give it a capability the Radeon simply does not have. The 20 RT cores provide ray tracing hardware that is five times denser than the Radeon's 4 RT cores.

The AMD Radeon 840M wins in efficiency and integration scenarios. Its 15 W TDP is one-eighth the Jetson's 120 W, making it suitable for power-constrained portable devices. Its higher boost clock of 2900 MHz indicates a different performance profile, favoring burst workloads over sustained compute. Its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 means it can run conventional graphics applications, which the Jetson cannot with its N/A API listings.

The Radeon's portable device dependent display outputs contrast with the Jetson's complete lack of outputs. That makes the Radeon the only one of the two that can drive a display. The Jetson is clearly a compute accelerator, not a graphics card.

For a mobile device needing graphics output and low power, the Radeon 840M is the appropriate choice. For a server deployment requiring massive memory capacity, tensor performance, and high FP32 throughput, the Jetson T5000 is the only option that fits. The benchmark data does not contradict this split, as no head-to-head results exist to suggest otherwise.
