Intel Arc Pro B390 vs NVIDIA GeForce RTX 5050 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two GPUs. The NVIDIA GeForce RTX 5050 holds a substantial lead in raw compute performance, with its FP32 throughput measured at 13.17 TFLOPS compared to the Intel Arc Pro B390's 7.680 TFLOPS. That represents an advantage of roughly 71% for the NVIDIA part in single-precision floating-point work. The texture rate tells a similar story: the RTX 5050 delivers 205.8 GTexel/s against 120.0 GTexel/s for the Intel part, a 71.5% margin. Pixel throughput also favors NVIDIA, with 82.30 GPixel/s versus 60.00 GPixel/s, a 37% lead.

The RTX 5050's average benchmark score of 21035 places it at the 66th percentile among all GPUs in the database. Its nearest rivals include the AMD Radeon RX Vega M GL at 21153 (0.6% ahead), the AMD Radeon HD 8970M at 21237 (1% ahead), and the NVIDIA RTX A4000 Mobile at 21379 (1.6% ahead). The AMD Radeon RX 5600 XT trails the RTX 5050 by 1.6%. These tight margins indicate that the RTX 5050 sits in a competitive mid-range cluster, but the gap to the Intel Arc Pro B390 is far from tight.

The Intel Arc Pro B390, by contrast, has no recorded benchmark scores in the database and no nearest rivals listed. Its percentile ranking of 50 places it at the median of all GPUs, but without direct measurement data, the head-to-head comparison relies entirely on recorded specifications. The FP32, texture, and pixel rate figures above are the only quantitative basis for comparing performance, and in every one of those metrics, the RTX 5050 wins by a wide margin.

In FP16 compute, the situation flips in an interesting way. The Intel part achieves 15.36 TFLOPS using a 2:1 ratio, which is higher than its FP32 output. The RTX 5050 delivers 13.17 TFLOPS in FP16 with a 1:1 ratio, meaning it does not gain any throughput advantage from reduced precision. So while the RTX 5050 dominates in FP32, the Intel Arc Pro B390 actually exceeds it in FP16 peak throughput by roughly 17%. This is one of the few areas where the Intel part can claim a numerical win, though it comes with the caveat that the Intel implementation is not a true 1:1 FP16 path.

The RTX 5050's individual benchmark entries show consistent results across different test suites. Its 3DMark Steel Nomad DX12 score is 2502. Geekbench results include 90334 in OpenCL and 89381 in Vulkan. Passmark scores range from 66 in DirectX 12 to 186 in DirectX 9, with a G3D score of 17326 and a GPU compute score of 9184. The G2D score of 1113 reflects 2D graphics performance. The Intel Arc Pro B390 has no comparable entries, so the database contains no direct test-by-test comparison.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc Pro B390 uses the Xe3-LPG architecture built on a 3 nm process node manufactured by Intel. Its chip is codenamed Panther Lake. The NVIDIA GeForce RTX 5050 uses the Blackwell 2.0 architecture on a 5 nm process from TSMC, with the GB207 chip. The process node difference is significant: the Intel part uses a more advanced 3 nm node, which typically allows for higher density and lower power per transistor, while the NVIDIA part uses a mature 5 nm node.

The Intel part is an integrated graphics processor (IGP) with no separate memory. It uses system shared memory, meaning the GPU draws from the same memory pool as the CPU. The memory bus width is listed as "System Shared" and bandwidth is "System Dependent," which means performance scales with the host system's memory configuration. The NVIDIA part is a discrete GPU with 8 GB of dedicated GDDR6 memory on a 128 bit bus, delivering 320.0 GB/s of bandwidth. This is a critical architectural difference: dedicated memory with fixed bandwidth versus shared memory with variable bandwidth.

The transistor counts and die sizes are only recorded for the NVIDIA part. The RTX 5050 has 16,900 million transistors on a 149 mm² die, giving a transistor density of 113.4M per mm². The Intel part's transistor count and die size are listed as unknown. The manufacturing foundry also differs: Intel fabricates its own chip, while TSMC fabricates the NVIDIA chip.

The Intel Arc Pro B390 uses the Xe3-LPG architecture, which is a low-power graphics variant. Its shading units number 1536, with 48 texture mapping units and 24 render output units. It has 12 ray tracing cores but no tensor cores listed. The NVIDIA RTX 5050 has 2560 shading units, 80 TMUs, 32 ROPs, 20 ray tracing cores, and 80 tensor cores. The presence of tensor cores on the NVIDIA part enables AI-accelerated workloads that the Intel part cannot accelerate in the same way, since its tensor core count is not recorded.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. They are identical in API support. The power delivery architecture differs drastically: the Intel part is an IGP with no power connectors and a 130 W TDP for the NVIDIA part versus 80 W for the Intel part. The Intel part is embedded in a system, so power delivery is handled by the platform, while the NVIDIA part uses a single 8-pin power connector and recommends a 300 W power supply.

Where Each One Wins

The NVIDIA RTX 5050 wins decisively in raw rendering performance. Its FP32 throughput of 13.17 TFLOPS, texture rate of 205.8 GTexel/s, and pixel rate of 82.30 GPixel/s make it the stronger choice for traditional rasterization workloads, as long as those workloads are not bottlenecked by memory bandwidth. The 320.0 GB/s dedicated memory bandwidth provides consistent performance regardless of what else the system is doing. The 8 GB frame buffer also allows for larger textures and higher resolutions than the system shared memory approach of the Intel part.

The RTX 5050 also wins in ray tracing. It has 20 ray tracing cores compared to 12 for the Intel Arc Pro B390, and its higher overall compute throughput means each ray tracing core has more raw horsepower behind it. The tensor cores, 80 of them, add another dimension for AI-based rendering techniques such as DLSS-style upscaling, though the database does not record specific DLSS benchmarks. The RTX 5050's 66th percentile ranking among all GPUs reflects its position as a solid mid-range performer.

The Intel Arc Pro B390 wins in power efficiency at the package level. Its 80 W TDP is significantly lower than the 130 W TDP of the RTX 5050, and it requires no external power connectors. For compact or integrated systems where power delivery is limited, the Intel part is the only viable option among these two, since it is an IGP that does not occupy a slot. The RTX 5050 is a dual-slot card that needs a PCIe 5.0 x8 slot and a power supply rated at 300 W.

The Intel part also wins in FP16 compute throughput with 15.36 TFLOPS versus 13.17 TFLOPS for the NVIDIA part. This could benefit workloads that operate primarily in half precision, though the 2:1 ratio on the Intel part means it splits its FP32 units, while the NVIDIA part's 1:1 ratio indicates dedicated FP16 paths. The practical advantage depends on the software's precision requirements.

The process node advantage goes to Intel. The 3 nm node is more advanced than the 5 nm node used by NVIDIA, which could lead to better transistor density and potentially lower leakage currents, though the database does not record density figures for the Intel part. The Intel part is also newer, with a release date of January 2026, while the RTX 5050 launched in June 2025.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Intel Arc Pro B390 uses a Panther Lake chip with Xe3-LPG architecture, built on Intel's 3 nm process. The NVIDIA GeForce RTX 5050 uses the GB207 chip with Blackwell 2.0 architecture, built on TSMC's 5 nm process. The RTX 5050 has a recorded transistor count of 16,900 million and a die size of 149 mm², while the Intel part lists both as unknown.

Clock speeds differ significantly. The Intel Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5050 has a base clock of 2317 MHz and a boost clock of 2572 MHz. The memory clock for the RTX 5050 is 2500 MHz with 20 Gbps effective data rate, while the Intel part uses system shared memory with no dedicated clock.

Memory configuration is a major differentiator. The RTX 5050 has 8 GB of GDDR6 on a 128 bit bus with 320.0 GB/s bandwidth. The Intel Arc Pro B390 has system shared memory with system dependent bandwidth. The bus width is also system shared for the Intel part.

Compute unit counts show the NVIDIA part with more resources across the board: 2560 shading units versus 1536, 80 TMUs versus 48, 32 ROPs versus 24, 20 ray tracing cores versus 12, and 80 tensor cores versus none recorded for Intel. The pixel rate is 82.30 GPixel/s for NVIDIA and 60.00 GPixel/s for Intel. The texture rate is 205.8 GTexel/s for NVIDIA and 120.0 GTexel/s for Intel.

Power specifications differ by 50 W: the RTX 5050 has a 130 W TDP with a 1x 8-pin power connector and a 300 W suggested power supply, while the Intel Arc Pro B390 has an 80 W TDP with no power connectors and no suggested PSU listed. The slot width is dual-slot for NVIDIA and IGP for Intel. The bus interface is PCIe 5.0 x8 for NVIDIA and IGP for Intel.

Display outputs also differ. The RTX 5050 provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The Intel Arc Pro B390 lists display outputs as "Portable Device Dependent," reflecting its integrated nature. The NVIDIA part has a launch MSRP of 249 USD.
