AMD Radeon RX 7650 GRE vs Intel Arc B390 Comparison

Where Each One Wins

The recorded benchmark data splits these two graphics solutions into entirely different performance classes. The AMD Radeon RX 7650 GRE claims the only head-to-head victory, taking the 3DMark Steel Nomad DX12 test with a score of 2336 against Intel Arc B390's 1482. That advantage works out to a 57.6% delta, a decisive margin that places the AMD part in a different tier for modern DirectX 12 workloads.

The Intel Arc B390 does not register a single benchmark win in the database. Its sole recorded score, 1482 in the same Steel Nomad test, places it far behind. The use-case split, therefore, is straightforward: the AMD Radeon RX 7650 GRE is the option for discrete graphics performance, while the Intel Arc B390 functions as an integrated graphics processor (IGP) with a much lower output ceiling.

Looking at broader positioning, the AMD part sits at the 83rd percentile among all GPUs in the database, with an average benchmark score of 42723. Its nearest rivals include the NVIDIA GeForce RTX 4070 SUPER at 43223 (1.2% ahead), the NVIDIA Quadro M6000 24 GB at 43262 (1.2% ahead), the NVIDIA GeForce RTX 5050 Mobile at 43268 (1.3% ahead), and the NVIDIA Quadro M6000 at 43301 (1.3% ahead). The RX 7650 GRE trails these four by only a small margin, confirming it operates in the upper-midrange discrete segment.

The Intel Arc B390, by contrast, sits at the 9th percentile among all GPUs. Its average benchmark score is just 1482. Its nearest rivals are aging or low-end parts: the NVIDIA GeForce GT 520MX at 1463 (1.3% behind), the NVIDIA GeForce 800M at 1460 (1.5% behind), the NVIDIA GeForce GT 625 OEM at 1446 (2.5% behind), and the NVIDIA GeForce GT 710 at 1443 (2.7% behind). The B390 edges those parts out, but the margin is small and the absolute performance level is very low.

The data indicates that any task requiring substantial graphics compute, such as modern game rendering or GPU-accelerated content creation, belongs to the AMD Radeon RX 7650 GRE. The Intel Arc B390, given its IGP designation and low scores, is not a competitor for those workloads.

Architecture Differences

The two products diverge at nearly every architectural level. The AMD Radeon RX 7650 GRE uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename "Hotpink Bonefish." It belongs to the Navi III (RX 7000) generation and is manufactured on a 6 nm process at TSMC. The die measures 204 mm² and packs 13,300 million transistors, yielding a transistor density of 65.2M per mm².

The Intel Arc B390 uses the Panther Lake chip built on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is manufactured on a 3 nm process at Intel's own foundry. The database records its transistor count and die size as unknown, so no direct density comparison is possible.

Shader and fixed-function hardware differ sharply. The AMD part carries 2048 shading units, 128 texture mapping units (TMUs), and 64 raster output units (ROPs). It also includes 32 ray tracing cores. The Intel part has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The AMD part therefore has 33% more shaders, 2.67 times the TMUs, 2.67 times the ROPs, and 2.67 times the ray tracing cores.

Memory architecture is another major divergence. The AMD Radeon RX 7650 GRE uses 8 GB of GDDR6 memory on a 128-bit bus, with memory clocks at 2250 MHz (18 Gbps effective) and 288.0 GB/s of bandwidth. The Intel Arc B390 uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent. That means the B390's memory performance depends entirely on the host platform's memory configuration, and it cannot match a dedicated GDDR6 solution.

The AMD card's compute rates reflect its large shader array. It delivers 22.08 TFLOPS FP32 and 22.08 TFLOPS FP16 at a 1:1 ratio. The Intel part delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 at a 2:1 ratio. The AMD part is roughly 2.9 times faster in FP32 and about 1.4 times faster in FP16, though the Intel part's FP16 ratio suggests a different compute priority.

Clock behavior also differs. The AMD card runs a base clock of 1720 MHz, a boost of 2695 MHz, and a game clock of 2350 MHz. The Intel IGP runs a base of 300 MHz and a boost of 2500 MHz, with no separate game clock listed. The AMD part's sustained clock is far higher, which contributes to its large performance lead despite the architectural differences.

Head-to-Head Benchmarks

The only direct comparison in the database is the 3DMark Steel Nomad DX12 test. The AMD Radeon RX 7650 GRE scores 2336, and the Intel Arc B390 scores 1482. The AMD part wins by 57.6%, a gap that is large enough to classify the two products in entirely different segments.

Context from nearest rivals reinforces this split. The AMD part's nearest rival, the NVIDIA GeForce RTX 4070 SUPER, scores 43223 on average, just 1.2% ahead of the RX 7650 GRE's 42723 average. That places the RX 7650 GRE in the same performance band as a high-end desktop GPU from the previous generation. The Intel Arc B390, in contrast, is only 1.3% ahead of the NVIDIA GeForce GT 520MX, a very old entry-level part. The B390's 9th percentile ranking confirms that it sits near the bottom of the database.

The delta between the two parts in the Steel Nomad test, 57.6%, is consistent with their differences in raw compute resources. The AMD part has more than double the FP32 throughput (22.08 vs 7.68 TFLOPS), more than double the texture rate (345.0 vs 120.0 GTexel/s), and nearly triple the pixel rate (172.5 vs 60.00 GPixel/s). These resource advantages translate directly into the benchmark gap.

For users comparing these two in the database, the numbers indicate that the AMD Radeon RX 7650 GRE is the only one suitable for DirectX 12 gaming at any meaningful resolution. The Intel Arc B390's 1482 score in Steel Nomad is below the range where modern games can run smoothly, and its nearest rivals, all scoring near 1443 to 1463, are parts from a much older era.
