Intel Arc B770 vs NVIDIA GeForce RTX 4070 Comparison

Intel Arc B770 and NVIDIA GeForce RTX 4070 represent two distinct approaches to the same performance class, yet the recorded data for the Arc B770 is notably sparse. The database contains a full benchmark profile for the RTX 4070, including ten individual test scores, an average score of 37648, and a percentile ranking of 81 against all GPUs. In contrast, the Arc B770 has no benchmark entries, no average score, and a percentile ranking of 50. This asymmetry in available data fundamentally shapes the comparison, as the analysis must rely on architectural specifications and the RTX 4070's measured performance to infer the competitive landscape.

Where Each One Wins

The RTX 4070 demonstrates clear wins in every recorded benchmark category, simply because it is the only one of the two with measured scores. Its 3DMark Steel Nomad DX12 result of 3854 indicates strong modern DirectX 12 rasterization performance. The Geekbench OpenCL score of 154858 and Vulkan score of 174152 show robust cross-API compute and graphics capabilities. PassMark results reinforce this pattern: DirectX 10 scoring 139, DirectX 11 scoring 244, DirectX 12 scoring 103, and DirectX 9 scoring 320. The PassMark G3D score of 26927 and GPU compute score of 14720 further confirm a well-rounded profile. The G2D score of 1164 suggests competent 2D and display operations.

The Arc B770, by the numbers available, has no wins to claim in the database. Its percentile ranking of 50 versus the RTX 4070's 81 indicates that the Intel card sits at the median of all GPUs in the database, while the NVIDIA card outperforms 81 percent of all recorded GPUs. The average benchmark score of zero for the Arc B770, compared to 37648 for the RTX 4070, leaves no measured basis for an Intel advantage. The RTX 4070 also holds a narrow lead over its nearest rivals: it sits 0.1 percent ahead of the NVIDIA Tesla P4, 0.4 percent ahead of the AMD Radeon RX Vega 56, 1.3 percent ahead of the AMD Radeon PRO W6400, and trails the NVIDIA GeForce RTX 4080 Mobile by 1.3 percent. These margins position the RTX 4070 as a firmly mid-to-upper-tier performer.

Architecture Differences

The two GPUs are built on different architectures and use different silicon. The Intel Arc B770 uses the BMG-G31 chip with the Xe2-HPG architecture, part of the Battlemage generation for Arc 7. The NVIDIA GeForce RTX 4070 uses the AD104 chip with the Ada Lovelace architecture, part of the GeForce 40-series. Both use a 5 nm process node at TSMC, so the manufacturing process is identical. The physical design differs: the Arc B770 has a die size of 368 mm², while the RTX 4070 is smaller at 294 mm². The NVIDIA chip contains 35,800 million transistors, giving a density of 121.8 million transistors per mm², while the Intel transistor count is listed as unknown.

Memory configuration shows a clear split. The Arc B770 offers 16 GB of GDDR6 on a 256 bit bus, yielding 512.0 GB/s of bandwidth. The RTX 4070 offers 12 GB of GDDR6X on a 192 bit bus, yielding 504.2 GB/s. The Intel card has more capacity and a slightly wider bus, resulting in a modest bandwidth advantage. Clock behavior also differs: the Arc B770 has a base clock of 2100 MHz and a boost of 2400 MHz, while the RTX 4070 has a lower base of 1920 MHz but a higher boost of 2475 MHz. The memory clocks are stated differently, with the Intel card at 2000 MHz or 16 Gbps effective and the NVIDIA card at 1313 MHz or 21 Gbps effective.

Compute resources are distributed differently. The Arc B770 has 4096 shading units, 256 texture mapping units, and 128 render output units. The RTX 4070 has 5888 shading units, 184 TMUs, and 64 ROPs. The Intel card has 32 ray tracing cores, while the NVIDIA card has 46. The RTX 4070 includes 184 tensor cores; the Arc B770 lists no tensor core count. These differences produce divergent peak rates: the Arc B770 reaches 307.2 GPixel/s pixel rate and 614.4 GTexel/s texture rate, while the RTX 4070 reaches 158.4 GPixel/s and 455.4 GTexel/s. Floating point performance favors NVIDIA: 29.15 TFLOPS FP32 versus 19.66 TFLOPS for Intel. FP16 shows a different relationship: the Arc B770 delivers 39.32 TFLOPS with a 2:1 ratio, while the RTX 4070 delivers 29.15 TFLOPS with a 1:1 ratio.

The Verdict

From the recorded data, the RTX 4070 is the only GPU with measurable performance in the database. Its average benchmark score of 37648 and 81st percentile ranking place it clearly above the Arc B770's empty record and 50th percentile default. The RTX 4070 also shows balanced results across DirectX 9, 10, 11, and 12 workloads, plus strong compute scores in Geekbench OpenCL and Vulkan. The RTX 4070's 12 GB of GDDR6X memory and 504.2 GB/s bandwidth serve its 29.15 TFLOPS FP32 throughput, while its 184 tensor cores and 46 ray tracing cores support feature-rich workloads.

The Arc B770 presents a specification sheet that looks competitive on paper: 16 GB of GDDR6, 512.0 GB/s bandwidth, 4096 shading units, and a 368 mm² die. Its higher pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s suggest strong fill-rate potential. The 39.32 TFLOPS FP16 figure indicates double-rate compute capability that the RTX 4070 does not match. However, without benchmark scores, these specifications cannot be validated against real workloads. The data suggests a user choosing between these two cards should rely on the RTX 4070's measured results unless the Arc B770's larger memory capacity or higher fill rates are the deciding factor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Arc B770 and the RTX 4070. The comparison therefore relies on the RTX 4070's individual scores and the architectural data for both. The RTX 4070's 3DMark Steel Nomad DX12 score of 3854 serves as a reference point for modern gaming workloads. In Geekbench, the Vulkan score of 174152 exceeds the OpenCL score of 154858, indicating that the NVIDIA card performs slightly better under Vulkan in this test. PassMark results show a range across API generations: DirectX 9 scores highest at 320, DirectX 11 at 244, DirectX 10 at 139, and DirectX 12 at 103. The G3D score of 26927 and GPU compute score of 14720 complete the picture.

The nearest rival data for the RTX 4070 provides context. The Tesla P4 scores 37628, a 0.1 percent delta. The Radeon RX Vega 56 scores 37507, a 0.4 percent delta. The Radeon PRO W6400 scores 37157, a 1.3 percent delta. The RTX 4080 Mobile scores 38135, meaning the desktop RTX 4070 trails it by 1.3 percent. These margins are small, confirming that the RTX 4070 sits in a tightly contested performance band.

The Arc B770's specifications suggest where it might compete, but without scores, any head-to-head claim is speculative. Its 512.0 GB/s bandwidth nearly matches the RTX 4070's 504.2 GB/s. Its 128 ROPs and 256 TMUs outnumber the RTX 4070's 64 ROPs and 184 TMUs, which could translate to higher fill rates in certain workloads. The 16 GB frame buffer doubles the NVIDIA card's capacity, which matters for large textures or compute tasks. On the other hand, the RTX 4070's 5888 shading units and 29.15 TFLOPS FP32 outclass the Intel card's 4096 shading units and 19.66 TFLOPS, suggesting an advantage in shader-bound scenarios.
