AMD Steam Machine GPU vs Intel Arc Pro B50 Comparison

The Verdict

The data presents a clear split between two very different GPU designs. The AMD Steam Machine GPU, built on the Navi 33 chip with RDNA 3.0 architecture, is positioned as a high-performance console component. The Intel Arc Pro B50, using the BMG-G21 chip with Xe2-HPG architecture, is a professional workstation card. The recorded benchmarks show the Intel Arc Pro B50 holds a 50th percentile rank among all GPUs, while the AMD Steam Machine GPU has no recorded benchmark scores in the database, making direct performance comparisons impossible from the available data.

The Intel Arc Pro B50 has an average benchmark score of 2660 across its recorded tests. Its nearest rivals in the database include the NVIDIA GeForce GT 1030 at 2662 (0.1% behind), the NVIDIA Quadro K1100M at 2664 (0.2% behind), the NVIDIA GeForce GT 440 at 2645 (0.6% ahead), and the NVIDIA GeForce RTX 5070 SUPER at 2690 (1.1% behind). These deltas indicate the Arc Pro B50 sits in a narrow performance band around these competitors, with no significant advantage or disadvantage over any of them in aggregate scoring.

For the AMD Steam Machine GPU, the absence of benchmark data means the database cannot confirm its performance tier. Its percentile rank of 50 suggests it sits at the median of all GPUs, but this is not supported by actual test scores. The card's specifications, however, indicate a design focused on raw throughput rather than professional compute features. The Intel Arc Pro B50 is the only option with verified measurements, and it is the appropriate choice for users who need documented performance data and professional display outputs.

Where Each One Wins

The Intel Arc Pro B50 demonstrates clear strengths in specific benchmark categories. Its PassMark G3D score of 12553 is its highest recorded result, indicating solid overall graphics performance. The PassMark G2D score of 717 shows competent 2D acceleration. The GPU compute score of 6037 confirms respectable compute capabilities for professional workloads. The DirectX 11 test score of 100 is the highest among its DirectX tests, suggesting strong legacy API performance. The DirectX 9 score of 144 also indicates good older-game compatibility. The 3DMark Steel Nomad DX12 score of 1604 provides a modern API data point.

The AMD Steam Machine GPU wins on architectural design for gaming. Its pixel rate of 156.8 GPixel/s is nearly four times higher than the Intel Arc Pro B50's 41.60 GPixel/s. Its FP32 throughput of 17.56 TFLOPS exceeds the Intel card's 10.65 TFLOPS by a substantial margin. The AMD card's 288.0 GB/s memory bandwidth is higher than the Intel card's 224.0 GB/s. These specifications suggest the Steam Machine GPU would excel in resolution-heavy gaming scenarios, but without benchmark scores, this remains an inference from specifications rather than measured results.

The Intel Arc Pro B50 wins on power efficiency and professional features. Its 70 W TDP is significantly lower than the AMD card's 110 W. The Intel card requires only a 250 W suggested PSU, while the AMD card's power connector specification is listed as none. The Intel card offers four mini-DisplayPort 2.1 outputs, compared to the AMD card's single HDMI 2.1a and single DisplayPort 2.1. For multi-display professional setups, the Intel card has a clear connectivity advantage.

Architecture Differences

The two GPUs use fundamentally different architectures. The AMD Steam Machine GPU is built on RDNA 3.0 architecture with the codename Hotpink Bonefish, belonging to the Console GPU (Valve) generation. It uses a 6 nm process from TSMC. The Intel Arc Pro B50 uses Xe2-HPG architecture under the Battlemage (Pro Series) generation, fabricated on a 5 nm TSMC process. The smaller process node gives Intel a density advantage.

Transistor counts differ substantially. The AMD chip contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Intel chip contains 19,600 million transistors on a 272 mm² die, achieving 72.1 million per square millimeter. The Intel die is larger and denser, reflecting its more complex compute architecture.

Core configurations diverge significantly. The AMD card has 1792 shading units, 112 texture mapping units, and 64 ROPs. It also includes 28 ray tracing cores. The Intel card has 2048 shading units, 128 TMUs, but only 16 ROPs. It includes 16 ray tracing cores. The AMD card's higher ROP count directly explains its much higher pixel rate. The Intel card's higher shading unit and TMU counts support its higher texture rate of 332.8 GTexel/s versus the AMD card's 274.4 GTexel/s.

Memory architectures differ in capacity and speed. The AMD card uses 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. The Intel card uses 16 GB of GDDR6 on the same 128-bit bus width but with 224.0 GB/s bandwidth. The AMD card's memory clock is 2250 MHz (18 Gbps effective), while the Intel card runs at 1750 MHz (14 Gbps effective). The AMD card has less capacity but higher bandwidth, while the Intel card doubles capacity at lower speed.

Clock behavior also differs. The AMD card specifies base, boost, and game clocks of 1720 MHz, 2450 MHz, and 2250 MHz respectively. The Intel card lists only base (1700 MHz) and boost (2600 MHz) clocks, with no game clock specification. The Intel card has a higher boost clock, but the AMD card's game clock provides a stable performance target for sustained gaming workloads.

Head-to-Head Benchmarks

The database records no head-to-head benchmark comparisons between the AMD Steam Machine GPU and the Intel Arc Pro B50. The winsA and winsB fields both show zero. This absence of direct measurement data means the comparison must rely on the Intel card's individual benchmark results and the architectural specifications of both cards.

The Intel Arc Pro B50's recorded performance shows a clear profile. Its PassMark G3D score of 12553 is the strongest result, followed by the GPU compute score of 6037. The 3DMark Steel Nomad DX12 score of 1604 represents modern API performance. The DirectX legacy tests show scores of 144 for DirectX 9, 100 for DirectX 11, 64 for DirectX 12, and 58 for DirectX 10. The G2D score of 717 completes the picture. These results place the card in the company of the NVIDIA GeForce GT 1030 and Quadro K1100M, with the RTX 5070 SUPER being 1.1% faster and the GT 440 being 0.6% slower.

For the AMD Steam Machine GPU, the specification data provides the only comparison points. Its FP32 throughput of 17.56 TFLOPS is 64.9% higher than the Intel card's 10.65 TFLOPS. Its pixel rate of 156.8 GPixel/s is 277% higher than the Intel card's 41.60 GPixel/s. Its texture rate of 274.4 GTexel/s, however, is lower than the Intel card's 332.8 GTexel/s, a difference of 21.3% in Intel's favor. The AMD card's memory bandwidth of 288.0 GB/s is 28.6% higher than the Intel card's 224.0 GB/s.

The FP16 capabilities show a notable divergence. The AMD card achieves 17.56 TFLOPS in FP16 with a 1:1 ratio to FP32. The Intel card achieves 21.30 TFLOPS in FP16 with a 2:1 ratio, meaning it processes half-precision at double the rate of single-precision. For workloads that leverage FP16, the Intel card has an advantage, while the AMD card's 1:1 ratio indicates it treats FP16 and FP32 identically.
