AMD Radeon 820M vs NVIDIA Jetson T5000 Comparison

Where Each One Wins

The recorded data presents two fundamentally different devices, and the benchmark wins split accordingly. The AMD Radeon 820M is an integrated graphics processor designed for mobile computing, while the NVIDIA Jetson T5000 is a server-class module with no display outputs. In the database, the Radeon 820M holds wins in areas related to graphics API support and display functionality. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the Jetson T5000 lists N/A for all three APIs. For any workload that requires a conventional graphics pipeline, the Radeon 820M is the only option with functional API coverage.

The NVIDIA Jetson T5000 wins decisively in raw compute performance. Its FP32 throughput of 8.064 TFLOPS dwarfs the Radeon 820M's 716.8 GFLOPS, a 11.25x advantage. The pixel rate also favors NVIDIA heavily: 50.40 GPixel/s versus 11.20 GPixel/s, a 4.5x margin. Texture rate tells a similar story, with 126.0 GTexel/s against 22.40 GTexel/s. The Jetson T5000 also offers substantially more memory bandwidth at 273.2 GB/s, while the Radeon 820M relies on system-shared memory with bandwidth described only as system dependent.

The use-case split is clear. For graphics rendering, gaming, or any display-driven application, the Radeon 820M wins because it has the API support and display outputs. For compute-heavy server workloads, neural network inference, or high-throughput parallel processing, the Jetson T5000 wins on raw numbers alone. The Jetson T5000's 2560 shading units, 80 texture mapping units, and 32 ROPs vastly exceed the Radeon 820M's 128 shaders, 8 TMUs, and 4 ROPs. The Radeon 820M's 2 ray tracing cores and the Jetson T5000's 20 ray tracing cores further separate their compute capabilities, while the Jetson T5000 adds 96 tensor cores that the Radeon 820M lacks entirely.

Architecture Differences

The two devices come from different manufacturers, use different process nodes, and target entirely different segments. The AMD Radeon 820M uses the Krackan Point 2 chip built on RDNA 3.5 architecture, belonging to the Navi III IGP (Strix Point Mobile) generation. It is fabricated on a 4 nm process at TSMC. The NVIDIA Jetson T5000 uses the GB10B chip with Blackwell architecture, part of the Server Blackwell (Bxx) generation, built on a 5 nm TSMC process. The die size for the Jetson T5000 is recorded as 391 mm², while the Radeon 820M's die size is unknown.

Clock behavior differs significantly between the two. The Radeon 820M operates with a base clock of 400 MHz and a boost clock of 2800 MHz. The Jetson T5000 runs at a base of 1386 MHz and a boost of 1575 MHz. Despite the Jetson T5000's lower boost clock, its massive shading unit count delivers far greater aggregate throughput. Memory configurations could hardly be more different. The Radeon 820M uses system-shared memory with a system-shared bus width and system-dependent bandwidth. The Jetson T5000 packs 128 GB of LPDDR5X memory on a 256 bit bus, delivering 273.2 GB/s of bandwidth. Memory clock for the Jetson T5000 is listed as 1067 MHz with 8.5 Gbps effective data rate.

Compute resources show the scale of the gap. The Radeon 820M has 128 shading units, 8 TMUs, and 4 ROPs. The Jetson T5000 has 2560 shading units, 80 TMUs, and 32 ROPs. Ray tracing cores number 2 versus 20, and tensor cores are absent on the AMD part while the NVIDIA chip carries 96. FP16 performance matches each device's FP32 rate at a 1:1 ratio, meaning the Jetson T5000 delivers 8.064 TFLOPS in both precisions, while the Radeon 820M manages 716.8 GFLOPS in both.

Power and physical characteristics also diverge. The Radeon 820M has a TDP of 15 W, while the Jetson T5000 draws 120 W. Both are listed as IGP slot width with no power connectors. The Jetson T5000 suggests a 300 W PSU, while the Radeon 820M has no suggested PSU listed. The bus interface differs: PCIe 4.0 x8 for AMD, PCIe 5.0 x8 for NVIDIA. Display outputs on the Radeon 820M are portable device dependent, while the Jetson T5000 has no outputs at all. Physical dimensions for the Jetson T5000 are recorded as 87 mm by 100 mm by 15 mm, while the Radeon 820M lists no dimensions.

The production status for both is Active. The Radeon 820M's release date is 2025-02-28, with the Jetson T5000 following on 2025-08-26. The Radeon 820M's predecessor is Navi II IGP, while the Jetson T5000's predecessor is Server Hopper and its successor is Server Rubin. The Jetson T5000 has a launch MSRP of 2,999 USD; the Radeon 820M has no launch MSRP recorded.

The Verdict

The data indicates these are not competing products in the conventional sense. The AMD Radeon 820M is an integrated GPU for mobile devices with a 15 W TDP, system-shared memory, and full graphics API support. The NVIDIA Jetson T5000 is a 120 W server module with 128 GB of dedicated LPDDR5X memory, no display outputs, and no graphics API support. Anyone selecting between them based on the database records must first determine whether the workload requires display output or conventional graphics APIs.

For a portable device needing graphics acceleration within a 15 W envelope, the Radeon 820M is the only viable option. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and its display outputs are portable device dependent, meaning it integrates into mobile systems. Its 400 MHz base clock and 2800 MHz boost clock indicate a design that ramps aggressively under load within a low power budget.

For server-side compute, the Jetson T5000 dominates every measurable performance category. Its FP32 throughput of 8.064 TFLOPS is 11.25x the Radeon 820M's 716.8 GFLOPS. Its 273.2 GB/s memory bandwidth versus system-dependent shared memory gives it a decisive advantage in memory-bound workloads. The presence of 96 tensor cores makes it suited for AI and machine learning inference tasks that the Radeon 820M cannot accelerate through dedicated tensor hardware. The Jetson T5000's 20 ray tracing cores also outnumber the Radeon 820M's 2, though neither device lists benchmark scores in the database.

The percentile ranking for both devices is identical at 50, and both have an average benchmark score of 0, reflecting the absence of recorded benchmark results. The verdict from the data is straightforward: choose the Radeon 820M for graphics-capable mobile integration, choose the Jetson T5000 for raw compute density and server deployment. The 120 W TDP of the Jetson T5000, its 300 W suggested PSU, and its PCIe 5.0 x8 interface all point to a system designed for sustained heavy workloads, not power-sensitive mobile use.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two devices, but the specification data provides ample ground for comparison. The most significant margin appears in FP32 throughput. The Jetson T5000's 8.064 TFLOPS against the Radeon 820M's 716.8 GFLOPS represents an 11.25x advantage. This gap stems from the Jetson T5000's 2560 shading units compared to 128 on the Radeon 820M. In FP16, the same ratio holds, with both devices offering 1:1 FP16 to FP32 rates.

Pixel throughput favors the Jetson T5000 by a 4.5x margin, with 50.40 GPixel/s versus 11.20 GPixel/s. The Radeon 820M's 4 ROPs simply cannot match the Jetson T5000's 32 ROPs. Texture fill rate shows a 5.63x gap, with 126.0 GTexel/s on the NVIDIA part versus 22.40 GTexel/s on the AMD part, driven by 80 TMUs against 8.

Memory bandwidth presents one of the starkest contrasts. The Jetson T5000 provides 273.2 GB/s of dedicated bandwidth, while the Radeon 820M's bandwidth is listed as system dependent, with no fixed figure available. The Jetson T5000's 128 GB memory capacity and 256 bit bus width contrast sharply with the Radeon 820M's fully shared memory architecture.

Clock speeds tell an interesting reversal. The Radeon 820M boosts to 2800 MHz, far above the Jetson T5000's 1575 MHz boost. Yet the NVIDIA chip's 20x shading unit advantage overwhelms the AMD clock advantage. The base clocks show a similar pattern, with 400 MHz on the AMD part versus 1386 MHz on the NVIDIA part. The Radeon 820M's low base clock and high boost clock suggest a power-optimized design that ramps up for short bursts, while the Jetson T5000's narrower clock range indicates sustained operation.

Ray tracing resources differ by 10x, with 20 cores on the Jetson T5000 and 2 on the Radeon 820M. Tensor cores exist only on the Jetson T5000 at 96, which is a decisive factor for any machine learning workload. The bus interface also differs, with PCIe 4.0 x8 on the AMD part and PCIe 5.0 x8 on the NVIDIA part, doubling the potential host interconnect bandwidth for the Jetson T5000.

Process technology slightly favors AMD at 4 nm versus 5 nm, though both use TSMC as the foundry. The Jetson T5000's die size of 391 mm² accommodates its far larger compute array. Power consumption scales accordingly, with the Jetson T5000's 120 W TDP eight times the Radeon 820M's 15 W TDP. The Radeon 820M's launch occurred on 2025-02-28, roughly six months before the Jetson T5000's 2025-08-26 release, and the Jetson T5000 lists a launch MSRP of 2,999 USD while the Radeon 820M has none recorded.
