The Verdict

The data presents two very different workstation solutions. The Intel Arc Pro B390 is an integrated GPU, meaning it shares system memory and draws from the host platform's resources. It offers higher raw compute figures in FP32 (7.680 TFLOPS) and FP16 (15.36 TFLOPS with 2:1 ratio), along with a faster boost clock of 2500 MHz. Its TDP of 80 W reflects that it is built into the processor package rather than being a standalone card.

The NVIDIA RTX A1000 is a discrete, single-slot PCIe 4.0 x8 card with its own 8 GB of GDDR6 memory and 192.0 GB/s of dedicated bandwidth. It has more shading units (2304 vs 1536), more TMUs (72 vs 48), more ROPs (32 vs 24), more RT cores (18 vs 12), and 72 tensor cores. Its power draw is lower at 50 W, and its performance percentile of 79 places it among capable workstation GPUs, with benchmark scores of 969 in 3DMark Steel Nomad DX12, 52078 in Geekbench OpenCL, and 49574 in Geekbench Vulkan.

For users building a compact workstation where a discrete GPU slot is unavailable, or where system memory is plentiful and shared memory is acceptable, the Intel Arc Pro B390 provides the higher FP32 compute ceiling and a much higher boost clock. For those who need guaranteed dedicated VRAM, tensor cores for AI workloads, and a proven track record in the database's benchmark percentile rankings, the RTX A1000 is the safer choice. The Intel part's percentile of 50 indicates it sits at the midpoint of all GPUs, whereas the RTX A1000's 79th percentile shows it outperforms the majority of the field.

Head-to-Head Benchmarks

Direct comparative benchmark data between these two specific cards is not recorded in the database, so the analysis relies on their individual specifications and the RTX A1000's measured benchmark scores.

The NVIDIA RTX A1000 has three recorded benchmark results. In 3DMark Steel Nomad DX12 it scored 969. In Geekbench OpenCL it scored 52078, and in Geekbench Vulkan it scored 49574. These results give it an average benchmark score of 34207 and a 79th percentile ranking. Its nearest rivals in the database are the NVIDIA RTX A2000 12 GB with an average score of 34154 (0.2% behind), the AMD Radeon RX 560 XT with 34133 (0.2% behind), the NVIDIA TITAN V with 34355 (0.4% ahead), and the AMD Radeon RX 480 with 33997 (0.6% behind). This clustering shows the RTX A1000 sits in a tightly contested performance band.

The Intel Arc Pro B390 has no recorded benchmark scores, an average benchmark score of zero, and an empty nearest rivals list. Its performance can only be estimated from its specification sheet. The FP32 throughput of 7.680 TFLOPS exceeds the RTX A1000's 6.737 TFLOPS, a lead of about 14%. The texture rate of 120.0 GTexel/s also beats the RTX A1000's 105.3 GTexel/s, and the pixel rate of 60.00 GPixel/s is higher than the RTX A1000's 46.78 GPixel/s. These specification advantages suggest the Intel part may outperform the RTX A1000 in fill-rate-bound workloads, but without actual benchmark scores in the database, that remains an inference from the recorded data.

The RTX A1000 counters with a higher shading unit count (2304 vs 1536), more TMUs (72 vs 48), more ROPs (32 vs 24), more RT cores (18 vs 12), and the presence of 72 tensor cores, which the Intel part lacks entirely. The RTX A1000 also has dedicated memory bandwidth of 192.0 GB/s versus the Intel part's system-dependent bandwidth. For memory-heavy workloads, the discrete VRAM of the RTX A1000 provides a structural advantage that shared memory cannot match.

Specification Differences

The Intel Arc Pro B390 and NVIDIA RTX A1000 differ across nearly every major specification category.

The Intel part uses the Panther Lake chip with Xe3-LPG architecture, fabricated on Intel's 3 nm process node. It has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores.

Architecture Differences

The architecture gap between these two parts is substantial. The Intel Arc Pro B390 is built on Xe3-LPG, Intel's low-power graphics architecture, fabricated on a 3 nm process node from Intel's own foundry. The NVIDIA RTX A1000 is built on Ampere, NVIDIA's workstation architecture from the Ax000 generation, fabricated on Samsung's 8 nm process. The Intel node advantage is significant, with a much smaller process geometry, though the RTX A1000's transistor count is recorded as 8,700 million on a 200 mm² die with a density of 43.5M transistors per mm². The Intel part's transistor count and die size are listed as unknown in the database.

The RTX A1000 includes 72 tensor cores, which the Intel Arc Pro B390 does not have. This is a defining architectural difference: tensor cores enable accelerated AI and machine learning workloads, while the Intel part has no such hardware. The RTX A1000 also has more RT cores (18 vs 12), giving it a higher ray tracing hardware count, though both support DirectX 12 Ultimate with ray tracing capabilities.

FP16 processing differs markedly. The Intel Arc Pro B390 delivers 15.36 TFLOPS of FP16 with a 2:1 ratio relative to FP32, indicating it can process half-precision at double the rate of single-precision. The NVIDIA RTX A1000 delivers 6.737 TFLOPS of FP16 at a 1:1 ratio, meaning it processes half-precision at the same rate as FP32. For workloads that leverage FP16, the Intel part has a theoretical advantage, while the RTX A1000's ratio suggests a different design priority focused on consistent precision across formats.

The Intel part is an integrated GPU with system shared memory, meaning its memory subsystem is entirely dependent on the host platform. The RTX A1000 is a discrete GPU with dedicated GDDR6 memory. This fundamental architectural distinction affects latency, bandwidth consistency, and memory capacity availability. The RTX A1000's memory is fixed at 8 GB, while the Intel part can access however much system memory the host provides, but with system-dependent bandwidth.

Where Each One Wins

The Intel Arc Pro B390 wins in scenarios that favor raw compute throughput and fill rates. Its FP32 performance of 7.680 TFLOPS is higher than the RTX A1000's 6.737 TFLOPS, so single-precision compute tasks see a theoretical advantage. Its FP16 performance of 15.36 TFLOPS more than doubles the RTX A1000's 6.737 TFLOPS, making it the stronger choice for half-precision workloads if software can exploit the 2:1 ratio. Its texture rate of 120.0 GTexel/s and pixel rate of 60.00 GPixel/s both exceed the RTX A1000's 105.3 GTexel/s and 46.78 GPixel/s, indicating an edge in texture-heavy and pixel-fill-bound rendering. Its boost clock of 2500 MHz is substantially higher than the RTX A1000's 1462 MHz, which benefits latency-sensitive workloads that scale with clock speed. The 3 nm process node also suggests a more modern manufacturing approach than the RTX A1000's 8 nm node.

The NVIDIA RTX A1000 wins in scenarios that require dedicated memory, higher hardware resource counts, and proven measured performance. Its 8 GB of GDDR6 memory with 192.0 GB/s bandwidth provides consistent, dedicated memory performance that the Intel part cannot guarantee with system shared memory. Its 2304 shading units, 72 TMUs, and 32 ROPs give it more parallel hardware units than the Intel part's 1536 shading units, 48 TMUs, and 24 ROPs. The 72 tensor cores are exclusive to the RTX A1000, making it the only option here for tensor-accelerated AI workloads. Its 18 RT cores exceed the Intel part's 12, providing more ray tracing hardware. Its TDP of 50 W is lower than the Intel part's 80 W, making it more power-efficient in absolute terms. The RTX A1000 also has recorded benchmark scores and a 79th percentile ranking, placing it above the majority of GPUs in the database, while the Intel part's 50th percentile and zero recorded benchmarks leave its real-world standing unverified.

The RTX A1000's nearest rival data shows it competes within 0.6% of the NVIDIA RTX A2000 12 GB, AMD Radeon RX 560 XT, NVIDIA TITAN V, and AMD Radeon RX 480. This positions it in a familiar performance class with established peers. The Intel Arc Pro B390 has no such positioning data, so its competitive standing in the database is unmeasured. For users who need a discrete card with dedicated VRAM, tensor cores, and verified benchmark results, the RTX A1000 is the clear pick from the recorded data. For users who need maximum FP32 and FP16 throughput on an integrated solution with no additional card slot, the Intel Arc Pro B390 offers the higher specification figures.
