Intel Arc Pro B390 vs NVIDIA Jetson T4000 Comparison

Head-to-Head Benchmarks

The recorded database contains no completed benchmark runs for either the Intel Arc Pro B390 or the NVIDIA Jetson T4000. Both entries show an average benchmark score of zero and an empty benchmark history. Consequently, the head-to-head comparison cannot rely on measured performance deltas from actual workloads. What the data does provide is a percentile placement: both parts sit at the 50th percentile against all GPUs tracked in the database, indicating they occupy a similar middle-ground tier in the overall distribution of recorded graphics hardware.

Without direct benchmark scores, the comparative analysis must shift to specification-derived capabilities. The Intel Arc Pro B390 lists a peak FP32 throughput of 7.680 TFLOPS, while the NVIDIA Jetson T4000 lists 4.700 TFLOPS. That difference places the Intel part approximately 63% ahead in raw single-precision floating-point throughput. In FP16 compute, the gap widens further: the Arc Pro B390 delivers 15.36 TFLOPS with a 2:1 ratio, whereas the Jetson T4000 delivers 4.700 TFLOPS at a 1:1 ratio. The Intel part thus offers over three times the half-precision throughput on paper.

Pixel fillrate tells a similar story. The Arc Pro B390 achieves 60.00 GPixel/s, compared to 24.48 GPixel/s for the Jetson T4000. That represents a 145% advantage for the Intel part in pixel output. Texture fillrate shows 120.0 GTexel/s for the Arc Pro B390 versus 73.44 GTexel/s for the Jetson T4000, a 63% lead for Intel. These figures suggest the Arc Pro B390 holds a decisive edge in rasterization-bound workloads, assuming the shared-memory configuration does not bottleneck the implementation.

The Jetson T4000 counters with a memory specification that the Arc Pro B390 cannot match on paper. The NVIDIA part carries 64 GB of LPDDR5X memory across a 256-bit bus, yielding 273.2 GB/s of bandwidth. The Intel part uses system-shared memory with bandwidth described as system dependent. For workloads that stress memory capacity or sustained data movement, the Jetson T4000 presents a structural advantage that no amount of compute throughput can bypass.

Both parts share identical shading unit counts at 1536, identical TMU counts at 48, and identical ray-tracing core counts at 12. The ROP count differs: 24 for the Arc Pro B390 versus 16 for the Jetson T4000. That 8-ROP gap aligns with the pixel rate differential observed above. The Jetson T4000 additionally integrates 64 tensor cores, a feature class entirely absent from the Arc Pro B390's specification sheet.

Architecture Differences

The Intel Arc Pro B390 uses the Xe3-LPG architecture built on Panther Lake silicon, fabricated at Intel's 3 nm process node. The NVIDIA Jetson T4000 uses the Blackwell architecture on the GB10B chip, fabricated at TSMC's 5 nm process. These process nodes represent different manufacturing generations and different foundries, though the database does not record transistor counts for either part to enable density comparisons.

The Intel chip belongs to the Arc Graphics-WM (Panther Lake) generation, with a release date recorded as 2026-01-26. Its predecessor is listed as HD Graphics-WM. The NVIDIA chip belongs to the Server Blackwell (Bxx) generation, with a release date of 2026-01-04. Its predecessor is Server Hopper, and its successor is Server Rubin. The NVIDIA part entered the database roughly three weeks earlier than the Intel part.

Clock behavior differs substantially. The Arc Pro B390 lists a base clock of 300 MHz and a boost clock of 2500 MHz, an 8.3x boost range that indicates aggressive dynamic frequency scaling. The Jetson T4000 lists a fixed 1530 MHz for both base and boost, meaning no boost headroom beyond the nominal clock. The memory clock for the Jetson T4000 is 1067 MHz with 8.5 Gbps effective data rate, while the Intel part again relies on system-shared memory.

The NVIDIA die measures 391 mm², a figure recorded in the database. The Intel die size remains unknown. The Jetson T4000 uses a PCIe 5.0 x8 bus interface and includes no display outputs. The Arc Pro B390 uses an integrated graphics processor (IGP) bus interface with display outputs described as portable device dependent. Neither part requires external power connectors, with the Arc Pro B390 drawing an 80 W TDP and the Jetson T4000 drawing a 90 W TDP.

API support separates the two sharply. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not positioned as a general-purpose graphics rendering device in the consumer API sense. This reinforces the Jetson T4000's orientation toward embedded or server compute workloads rather than display-driven applications.

The Jetson T4000 includes 64 tensor cores, a feature absent from the Arc Pro B390's specification list. Tensor cores accelerate matrix operations commonly used in neural network inference and training. The Intel part relies on its 1536 shading units and 12 ray-tracing cores for general compute and graphics, with no dedicated tensor hardware recorded.

Where Each One Wins

The Intel Arc Pro B390 wins in every measured compute and graphics throughput category recorded in the database. Its FP32 output of 7.680 TFLOPS exceeds the Jetson T4000's 4.700 TFLOPS by a wide margin. Its FP16 output of 15.36 TFLOPS dwarfs the Jetson T4000's 4.700 TFLOPS, particularly because the Intel part uses a 2:1 ratio while the NVIDIA part operates at 1:1. Pixel rate of 60.00 GPixel/s versus 24.48 GPixel/s and texture rate of 120.0 GTexel/s versus 73.44 GTexel/s both favor Intel substantially. The Arc Pro B390 also supports the full modern graphics API stack with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it the only one of the two that can function as a general-purpose rendering device.

The NVIDIA Jetson T4000 wins in memory capacity, memory bandwidth, and form factor specificity. Its 64 GB of dedicated LPDDR5X memory with 273.2 GB/s bandwidth is a fixed resource, whereas the Intel part depends entirely on whatever system memory the host platform provides. The Jetson T4000 also includes 64 tensor cores, giving it a hardware path for matrix operations that the Intel part lacks. Its fixed 1530 MHz clock with no boost variability may appeal to environments requiring predictable performance envelopes. The Jetson T4000's die size of 391 mm² is recorded, while the Intel part's remains unknown, which suggests the NVIDIA design is a larger, more complex silicon implementation. The Jetson T4000 also has a recorded launch MSRP of 1,999 USD, whereas the Intel part has no listed MSRP.

The Verdict

The data points in opposite directions for these two parts. The Intel Arc Pro B390 is a rendering and compute device with strong rasterization throughput, modern API support, and a 3 nm process. Its 7.680 TFLOPS FP32, 60.00 GPixel/s pixel rate, and 120.0 GTexel/s texture rate position it as the superior choice for graphics workloads, particularly those that leverage DirectX 12 Ultimate features or Vulkan 1.4. The 80 W TDP and integrated design suggest deployment in portable or space-constrained systems where display output is required.

The NVIDIA Jetson T4000 is a server-oriented Blackwell part with 64 GB of fixed memory, 273.2 GB/s bandwidth, and 64 tensor cores. Its lack of graphics API support and absence of display outputs indicate it is not intended for conventional rendering. The 90 W TDP, PCIe 5.0 x8 interface, and 391 mm² die size align with embedded or edge server roles where memory capacity and tensor operations matter more than pixel throughput. The 1:1 FP16 ratio at 4.700 TFLOPS suggests the part prioritizes consistent precision over the 2:1 mixed-precision approach used by the Intel part.

Users requiring a graphics-capable processor with high fillrates and modern API coverage should select the Intel Arc Pro B390. Users requiring large fixed memory capacity, tensor core acceleration, and a server-oriented Blackwell architecture should select the NVIDIA Jetson T4000. The 50th percentile placement for both parts in the global database indicates neither sits at the top of the performance hierarchy, but each occupies a distinct functional niche that the other cannot fill.
