AMD Steam Machine GPU vs NVIDIA Jetson T4000 Comparison

Head-to-Head Benchmarks

The recorded data for both the AMD Steam Machine GPU and the NVIDIA Jetson T4000 shows no direct head-to-head benchmark results in the database. Neither device has an average benchmark score, and their percentile placements are identical at 50.0. This means the comparison must be drawn entirely from architectural specifications, memory configurations, and measured output rates.

The AMD Steam Machine GPU delivers a substantially higher raw compute throughput. Its FP32 output is recorded at 17.56 TFLOPS, which is 3.74 times the NVIDIA Jetson T4000's 4.700 TFLOPS. In practical terms, the AMD part processes over three times as many single-precision floating-point operations per second. The FP16 figures mirror this exactly: 17.56 TFLOPS for AMD versus 4.700 TFLOPS for NVIDIA, with both parts reporting a 1:1 ratio between FP16 and FP32.

The pixel throughput gap is even more pronounced. AMD records a pixel rate of 156.8 GPixel/s, while NVIDIA manages 24.48 GPixel/s. That is a 6.4 times advantage for the AMD Steam Machine GPU. The difference in texture rate tells a similar story: AMD posts 274.4 GTexel/s against NVIDIA's 73.44 GTexel/s, a 3.74 times margin. These output rates indicate that the AMD part is designed for high-resolution rendering pipelines, while the NVIDIA part is not structured around rasterization throughput.

Memory capacity favors NVIDIA decisively. The Jetson T4000 carries 64 GB of LPDDR5X across a 256 bit bus, whereas the Steam Machine GPU has 8 GB of GDDR6 on a 128 bit bus. That is an 8 times capacity advantage. However, bandwidth is nearly even: AMD records 288.0 GB/s, and NVIDIA records 273.2 GB/s. The AMD part achieves its bandwidth with a narrower bus and faster memory clocks. The Steam Machine GPU's memory clock is listed at 2250 MHz with 18 Gbps effective, while the Jetson T4000 runs at 1067 MHz with 8.5 Gbps effective.

Core counts show AMD with more shading units, more texture mapping units, and more render output units. AMD has 1792 shading units, 112 TMUs, and 64 ROPs. NVIDIA has 1536 shading units, 48 TMUs, and only 16 ROPs. The ray tracing core count also favors AMD: 28 RT cores against 12. NVIDIA does hold an advantage in tensor cores, listing 64 tensor cores to AMD's null entry. The AMD part has no tensor core field populated in the database.

Clock behavior differs in an important way. The AMD Steam Machine GPU has a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. The NVIDIA Jetson T4000 runs at a fixed 1530 MHz for both base and boost. This means the AMD part can scale its frequency upward under load, while the NVIDIA part stays flat. The gap in boost clocks alone is 920 MHz.

Power draw is close but not equal. AMD records a TDP of 110 W, while NVIDIA records 90 W. The Jetson T4000 also lists a suggested PSU of 250 W, a field that is not populated for the AMD part. Both devices use no external power connectors.

The Verdict

The data describes two devices with fundamentally different purposes. The AMD Steam Machine GPU is a rasterization-focused graphics processor. Its high pixel rate, high texture rate, and 17.56 TFLOPS FP32 output align with real-time rendering workloads. The NVIDIA Jetson T4000 is a server-class Blackwell part with a 64 GB memory pool, a 256 bit bus, and tensor cores. Its compute throughput is lower, but its memory capacity is eight times larger.

Benchmark results indicate that the AMD part wins on every raw rendering metric: pixel rate, texture rate, FP32, and FP16. The NVIDIA part wins on memory capacity, tensor core presence, and physical footprint. The Jetson T4000 is an IGP with no display outputs, while the Steam Machine GPU has one HDMI 2.1a port and one DisplayPort 2.1 port. For any workload that requires a display output, the AMD part is the only option between the two.

The AMD Steam Machine GPU is the choice for rendering workloads, gaming, and any task that depends on rasterization throughput. The NVIDIA Jetson T4000 is the choice for memory-bound server workloads, AI inference via its 64 tensor cores, and compact embedded deployments. The 90 W TDP and 15 mm width of the Jetson T4000 make it suitable for tightly constrained environments. The 110 W TDP and larger dimensions of the AMD part indicate a broader physical envelope.

Neither device has recorded benchmark scores in the database, so percentile comparisons are not available. The absence of head-to-head results means the verdict rests on architectural analysis rather than measured performance deltas.

Architecture Differences

The AMD Steam Machine GPU is built on RDNA 3.0 architecture with the codename Hotpink Bonefish, using the Navi 33 chip. It belongs to the Console GPU (Valve) generation. The NVIDIA Jetson T4000 is built on Blackwell architecture with the GB10B chip and belongs to the Server Blackwell (Bxx) generation.

The process nodes differ by one nanometer: AMD uses 6 nm, NVIDIA uses 5 nm. Both are TSMC parts, but the die sizes diverge sharply. AMD's die is 204 mm² with 13,300 million transistors. NVIDIA's die is 391 mm², nearly double the area, but its transistor count is not recorded in the database.

The cache and memory hierarchy are not directly comparable. AMD uses GDDR6 memory, which is a discrete memory type, while NVIDIA uses LPDDR5X, an integrated package memory. The NVIDIA part's 256 bit bus is twice the width of AMD's 128 bit bus, yet the bandwidth difference is small because AMD runs its memory at a much higher effective speed.

Compute architecture differs in specialization. AMD dedicates its silicon to shading units, TMUs, and ROPs, with 28 RT cores for ray tracing. NVIDIA distributes its resources across 1536 shading units, 48 TMUs, 16 ROPs, 12 RT cores, and 64 tensor cores. The presence of tensor cores on the NVIDIA part indicates a design focus on matrix operations, while the AMD part's high ROP and TMU counts indicate a design focus on rasterization.

The fixed clock behavior of the NVIDIA part, with base and boost both at 1530 MHz, contrasts with AMD's variable clock scheme. AMD's boost clock of 2450 MHz is 920 MHz higher than its base clock of 1720 MHz. This suggests the AMD part can adapt its frequency to thermal and power headroom. The NVIDIA part is locked at a single frequency.

API support also separates the two. AMD exposes DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for consumer graphics applications. NVIDIA lists N/A across all three APIs, reinforcing its server-oriented positioning. The Jetson T4000 has no display outputs, while the Steam Machine GPU has HDMI 2.1a and DisplayPort 2.1.

Where Each One Wins

The AMD Steam Machine GPU wins in every metric related to graphics rendering. Its pixel rate of 156.8 GPixel/s is 6.4 times the NVIDIA part's 24.48 GPixel/s. Its texture rate of 274.4 GTexel/s is 3.74 times NVIDIA's 73.44 GTexel/s. Its FP32 output of 17.56 TFLOPS is 3.74 times NVIDIA's 4.700 TFLOPS. The AMD part also has more shading units, more TMUs, more ROPs, and more RT cores. For any workload that involves drawing frames, shading geometry, or rasterizing triangles, the AMD Steam Machine GPU is the stronger part.

The AMD part also wins on memory bandwidth, recording 288.0 GB/s against NVIDIA's 273.2 GB/s. This is a modest margin, but it holds despite AMD having a narrower bus. The AMD part also supports modern graphics APIs, while the NVIDIA part lists none.

The NVIDIA Jetson T4000 wins on memory capacity with 64 GB, which is 8 times the AMD part's 8 GB. This makes it the stronger option for workloads that need to hold large datasets in memory. The NVIDIA part also has 64 tensor cores, a feature the AMD part does not list. For matrix-based workloads such as inference or training support, the Jetson T4000 has dedicated hardware that the Steam Machine GPU lacks.

The NVIDIA part wins on physical compactness. Its dimensions of 87 mm by 100 mm by 15 mm are far smaller than AMD's 156 mm by 152 mm by 162 mm. Its 90 W TDP is 20 W lower than the AMD part's 110 W. The Jetson T4000 is an IGP with no external power connectors and no display outputs, which suits embedded server deployments. The AMD part has display outputs and a larger footprint, which suits consumer-facing rendering systems.

The NVIDIA part also has a documented predecessor and successor, indicating an established product line. Its launch MSRP is recorded at 1,999 USD. The AMD part has no MSRP recorded and no lineage in the database.

In summary, the AMD Steam Machine GPU is the winner for rendering throughput, pixel output, texture output, and graphics API support. The NVIDIA Jetson T4000 is the winner for memory capacity, tensor core compute, compactness, and power efficiency. The choice between them depends entirely on whether the workload is graphics rendering or memory-bound server processing.
