AMD Radeon RX 9050 OEM vs Intel Arc B390 Comparison

# AMD Radeon RX 9050 OEM vs Intel Arc B390

Head-to-Head Benchmarks

The direct comparison between these two GPUs is complicated by the fact that the database contains a benchmark score for only one of the two cards. The AMD Radeon RX 9050 OEM has no recorded benchmark entries in the database, meaning its average benchmark score is listed as zero and its percentile rank against all GPUs sits at the 50th percentile. The Intel Arc B390, by contrast, has a single recorded 3DMark Steel Nomad DX12 result, scoring 1482 points, which places it in the 9th percentile of all GPUs in the database.

The lack of a comparable score for the AMD card means a direct head-to-head numerical comparison cannot be made from the recorded data. However, the Intel Arc B390's position relative to its nearest rivals provides context for its performance tier. The Arc B390 outperforms the NVIDIA GeForce GT 520MX by 1.3%, the NVIDIA GeForce 800M by 1.5%, the NVIDIA GeForce GT 625 OEM by 2.5%, and the NVIDIA GeForce GT 710 by 2.7%. These are very narrow margins, indicating that the Intel part occupies a performance class near the entry-level mobile segment, as defined by the nearest rivals in the database.

The AMD Radeon RX 9050 OEM, on the other hand, has no recorded benchmark data, so its wins column in the head-to-head table is zero, as is the corresponding column for the Intel card. The database simply does not yet contain the measurements needed to establish which card wins in any specific test. What can be stated from the available figures is that the Intel Arc B390 delivers a measurable, if modest, 3DMark Steel Nomad DX12 score, while the AMD card's performance remains unquantified in the database at this time.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The AMD Radeon RX 9050 OEM uses the Navi 44 chip, based on RDNA 4.0 architecture, belonging to the Navi IV (RX 9000) generation. It is fabricated on a 4 nm process at TSMC, with a transistor count of 29,700 million and a die size of 199 mm², yielding a transistor density of 149.2 million per square millimeter. The Intel Arc B390, by contrast, uses the Panther Lake chip, based on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel, with transistor count and die size listed as unknown, and no transistor density figure available.

The memory subsystems differ dramatically. The AMD card features 4 GB of GDDR6 memory on a 64-bit bus, with a memory clock of 2250 MHz (18 Gbps effective) and a bandwidth of 144.0 GB/s. The Intel Arc B390 uses system shared memory, with size, type, and bus width all listed as system shared, and bandwidth described as system dependent. This architectural choice means the Intel part relies on the host system's memory rather than dedicated VRAM, a fundamental difference in how each card accesses data.

The compute resources also diverge. The AMD Radeon RX 9050 OEM has 1024 shading units, 64 texture mapping units, 64 render output units, and 16 ray tracing cores. The Intel Arc B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Notably, the Intel card has 50% more shading units than the AMD card, but fewer TMUs and ROPs, and fewer ray tracing cores. The pixel rate for the AMD card is 166.4 GPixel/s, while the Intel card manages 60.00 GPixel/s. The texture rate for the AMD card is 166.4 GTexel/s, versus 120.0 GTexel/s for the Intel part.

Clock speeds show a different pattern. The AMD card has a base clock of 1330 MHz, a boost clock of 2600 MHz, and a game clock of 1920 MHz. The Intel card has a much lower base clock of 300 MHz, but a boost clock of 2500 MHz, with no game clock listed. The memory clock for AMD is 2250 MHz (18 Gbps effective), while the Intel card's memory clock is system shared. FP32 throughput for AMD is 10.65 TFLOPS, and FP16 is also 10.65 TFLOPS at a 1:1 ratio. The Intel card delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 at a 2:1 ratio, meaning it has substantially higher FP16 capability relative to its FP32 performance.

Where Each One Wins

Based on the recorded data, the Intel Arc B390 is the only card with a measurable benchmark score, so it wins the single recorded test by default. Its 1482 points in 3DMark Steel Nomad DX12, while placing it in the 9th percentile of all GPUs, does establish that the card is functional and delivers some level of 3D performance. The narrow margins over its nearest rivals suggest it sits at the bottom of the desktop GPU hierarchy in the database, but it does have a quantifiable result.

The AMD Radeon RX 9050 OEM, with no benchmark results in the database, cannot be said to win any recorded tests. However, its specifications suggest areas where it may hold advantages based on the available data. The AMD card has a significantly higher pixel rate (166.4 GPixel/s vs 60.00 GPixel/s) and texture rate (166.4 GTexel/s vs 120.0 GTexel/s), which could translate to better rasterization performance in fill-rate limited scenarios. Its FP32 throughput of 10.65 TFLOPS is roughly 39% higher than the Intel card's 7.680 TFLOPS, suggesting potentially stronger general-purpose compute and traditional shader workloads.

The Intel card, meanwhile, has more shading units (1536 vs 1024) and higher FP16 throughput (15.36 TFLOPS vs 10.65 TFLOPS), which could favor workloads that utilize half-precision math. The AMD card uses dedicated GDDR6 memory with 144.0 GB/s of bandwidth, while the Intel card depends on system shared memory with system dependent bandwidth, which is likely to be a disadvantage in memory-intensive scenarios. The AMD card also has more ray tracing cores (16 vs 12), though neither card's ray tracing performance is quantified in the database.

The Verdict

The data in the database points to very different use cases for these two GPUs. The Intel Arc B390 is an integrated graphics processor (IGP) with an 80 W TDP, using the Panther Lake chip on a 3 nm Intel process, with system shared memory and no power connectors. It is designed for portable devices, as indicated by its display outputs being listed as portable device dependent and its bus interface being IGP. Its single benchmark score of 1482 places it in the 9th percentile, meaning it performs near the bottom of all GPUs in the database, roughly on par with decade-old NVIDIA entry-level mobile parts like the GeForce GT 520MX and GT 710.

The AMD Radeon RX 9050 OEM is a discrete dual-slot card with a 92 W TDP, requiring a 1x 8-pin power connector and a 250 W suggested PSU, using a PCIe 5.0 x16 bus interface. It has dedicated 4 GB GDDR6 memory, a 64-bit bus, and 144.0 GB/s bandwidth. Its 50th percentile rank, while not based on any recorded benchmark score, suggests the database places it in the middle of the GPU distribution. The AMD card has no launch MSRP listed, and no benchmark scores, so its performance tier must be inferred from its specifications alone.

For users seeking a discrete GPU with dedicated memory, higher fill rates, and a standard PCIe slot form factor, the AMD Radeon RX 9050 OEM is the only option between these two. For portable devices or systems where integrated graphics with shared memory are the requirement, the Intel Arc B390 is the appropriate choice, though its benchmark data indicates it operates at the very low end of the performance spectrum. The selection between these two should be driven by form factor and memory architecture needs, as the benchmark data does not support a direct performance comparison.
