Intel Arc B370 vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Intel Arc B370 and NVIDIA RTX 3000 Mobile Ada Generation occupy different tiers of the mobile graphics landscape. The recorded data shows the Intel part is an integrated solution with modest compute resources, while the NVIDIA part is a dedicated mobile GPU with substantially higher specifications. The benchmark evidence, limited to a single 3DMark Steel Nomad DX12 run for the Intel Arc B370, places it in the 5th percentile of all GPUs. The RTX 3000 Mobile Ada Generation has no recorded benchmark scores in the database, so its 50th percentile ranking reflects its specification profile rather than direct measurements.

Where Each One Wins

The Intel Arc B370 wins in power efficiency by design. Its 25 W TDP is less than a quarter of the 115 W TDP of the RTX 3000 Mobile Ada Generation. This makes the Arc B370 suitable for thin, fanless, or passively cooled portable devices where thermal and power budgets are extremely tight. The integrated nature of the Arc B370, using the system's shared memory, eliminates the need for separate video memory allocation and reduces component count. The data shows the Arc B370 has no power connectors, which confirms it draws power through the motherboard rather than requiring a dedicated supply line.

The RTX 3000 Mobile Ada Generation wins in raw compute and graphics throughput. Its FP32 performance is 15.62 TFLOPS, which is 2.54 times the 6.144 TFLOPS of the Arc B370. The NVIDIA part also delivers 15.62 TFLOPS of FP16 performance in a 1:1 ratio, while the Intel part reaches 12.29 TFLOPS in a 2:1 ratio, meaning the NVIDIA GPU maintains its throughput across both precision formats. The RTX 3000 Mobile Ada Generation has 4608 shading units, 144 texture mapping units, and 48 render output units. The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The NVIDIA GPU has 3.6 times the shading units, 3.6 times the TMUs, and 2.4 times the ROPs.

The RTX 3000 Mobile Ada Generation also wins decisively in memory bandwidth. It uses 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The Arc B370 relies on system shared memory with bandwidth described as system dependent. In practical terms, the dedicated GDDR6 memory of the NVIDIA part provides predictable, high-bandwidth access for texture-heavy workloads, while the Intel part's performance depends entirely on the host system's memory configuration.

The RTX 3000 Mobile Ada Generation wins in ray tracing and AI acceleration features. It has 36 ray tracing cores and 144 tensor cores. The Arc B370 has 10 ray tracing cores and no tensor cores listed. This gives the NVIDIA GPU a substantial advantage in ray-traced rendering and any workload that can use tensor core acceleration.

Architecture Differences

The two GPUs come from different manufacturers and use different process technologies. The Intel Arc B370 uses the Xe3-LPG architecture built on Intel's 3 nm process node. The chip is codenamed Panther Lake and belongs to the Arc Graphics-M (Panther Lake) generation. The NVIDIA RTX 3000 Mobile Ada Generation uses the Ada Lovelace architecture built on TSMC's 5 nm process node. The chip is codenamed AD106 and belongs to the Ada-MW generation.

The NVIDIA part has publicly listed transistor and die data. It contains 22,900 million transistors on a 188 mm² die, giving a transistor density of 121.8 million transistors per mm². The Intel part has unknown transistor count and die size in the database, so a direct density comparison is not possible from recorded data.

Clock behavior differs significantly. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The NVIDIA RTX 3000 Mobile Ada Generation has a base clock of 1395 MHz and a boost clock of 1695 MHz.

The memory clock for the NVIDIA part is 2000 MHz with 16 Gbps effective data rate, while the Intel part's memory clock is listed as system shared.

The memory architecture is fundamentally different. The Intel Arc B370 uses system shared memory for size, type, bus width, and bandwidth. The NVIDIA RTX 3000 Mobile Ada Generation uses 8 GB of GDDR6 with a 128-bit bus and 256.0 GB/s bandwidth. The bus interface also differs: the Intel part uses an IGP (integrated graphics processor) interface, while the NVIDIA part uses PCIe 4.0 x16.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have display outputs described as portable device dependent. The NVIDIA part has a predecessor in Ampere-MW and a successor in Blackwell-MW. The Intel part has no predecessor or successor listed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc B370 and the NVIDIA RTX 3000 Mobile Ada Generation. The Intel part has a single recorded benchmark score: 1184 in 3DMark Steel Nomad DX12. The NVIDIA part has no recorded benchmark scores at all. Despite the absence of direct comparisons, the specification data provides clear performance deltas.

The largest advantage for the NVIDIA part is in FP32 compute. At 15.62 TFLOPS versus 6.144 TFLOPS, the NVIDIA GPU delivers 2.54 times the throughput. In real workloads, this translates to faster shader execution and higher frame rates in compute-bound scenarios. The texture rate shows an even larger gap: 244.1 GTexel/s versus 96.00 GTexel/s, which is 2.54 times higher. The pixel rate is 81.36 GPixel/s versus 48.00 GPixel/s, a 1.70 times advantage.

The shading unit count advantage is substantial. With 4608 shading units versus 1280, the NVIDIA GPU has 3.6 times the parallel processing lanes. The TMU count is 144 versus 40, also 3.6 times. The ROP count is 48 versus 20, a 2.4 times advantage. The ray tracing core count is 36 versus 10, a 3.6 times advantage. The NVIDIA GPU has 144 tensor cores, while the Intel part has none listed.

Memory bandwidth is another major differentiator. The NVIDIA part has 256.0 GB/s of dedicated GDDR6 bandwidth. The Intel part's bandwidth is system dependent, meaning it shares the host memory bus and competes with CPU and other system traffic. For texture-heavy and memory-intensive workloads, the NVIDIA part's dedicated bandwidth provides a significant advantage.

The Intel part's main advantages are in power efficiency and clock range. Its 25 W TDP versus 115 W represents a 78% reduction in power draw. The boost clock of 2400 MHz is 705 MHz higher than the NVIDIA part's 1695 MHz, which helps the Intel part close some of the gap in lightly threaded or clock-sensitive workloads. The base clock of 300 MHz allows very low idle power draw.

The benchmark percentile rankings reflect the specification gap. The Intel Arc B370 sits in the 5th percentile of all GPUs, while the NVIDIA RTX 3000 Mobile Ada Generation sits in the 50th percentile. The Intel part's nearest rivals in the database are older discrete and mobile GPUs: the ATI Mobility Radeon HD 5570 (1186, 0.2% higher), the ATI Radeon HD 5770 (1190, 0.5% higher), the AMD Radeon HD 7650M (1192, 0.7% higher), and the AMD FirePro M2000 (1168, 1.4% lower). This places the Arc B370's measured performance in the range of legacy low-end graphics hardware, not modern mid-range parts.

The Verdict

The data supports a clear separation of roles. The Intel Arc B370 is an integrated GPU designed for minimum power consumption and system simplicity. Its 25 W TDP, IGP bus interface, system shared memory, and lack of power connectors make it appropriate for ultra-portable devices where battery life and thermals take priority over graphics performance. Its measured 3DMark Steel Nomad DX12 score of 1184 and 5th percentile ranking indicate it handles only light graphics workloads.

The NVIDIA RTX 3000 Mobile Ada Generation is a dedicated mobile GPU with substantially higher specifications. Its 15.62 TFLOPS FP32 performance, 8 GB of GDDR6 memory with 256.0 GB/s bandwidth, 4608 shading units, 36 ray tracing cores, and 144 tensor cores position it for demanding gaming, content creation, and compute workloads. Its 115 W TDP requires robust cooling and power delivery, making it suitable for larger laptops and mobile workstations.

Users who need maximum graphics performance in a mobile platform should select the NVIDIA RTX 3000 Mobile Ada Generation based on its specification advantages across every compute metric. Users who prioritize minimal power draw and integrated simplicity should select the Intel Arc B370, which delivers usable graphics at a fraction of the power envelope. The absence of direct benchmark comparisons means these conclusions rest on the recorded specification deltas, which are consistent and large. The NVIDIA part leads in compute throughput, memory bandwidth, texture rate, pixel rate, and feature hardware. The Intel part leads in power efficiency and clock ceiling. There is no overlap in their intended performance classes.
