Intel Arc B770 vs NVIDIA RTX 1000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc B770 and the NVIDIA RTX 1000 Mobile Ada Generation shows two graphics processors aimed at very different segments of the market. The Arc B770 is a desktop part built on the Battlemage architecture, while the RTX 1000 is a mobile workstation component using the Ada Lovelace design. Their performance profiles, as derived from the specification sheets, diverge substantially across nearly every measurable category.

The most obvious gap appears in raw compute throughput. The Intel Arc B770 delivers 19.66 TFLOPS of FP32 performance, while the NVIDIA RTX 1000 Mobile Ada Generation produces 10.37 TFLOPS. That places the Arc B770 roughly 90% ahead of the RTX 1000 in single-precision floating-point work. In FP16 calculations, the gap widens further. The Arc B770 achieves 39.32 TFLOPS using a 2:1 ratio, whereas the RTX 1000 manages 10.37 TFLOPS with a 1:1 ratio. The Intel part therefore offers nearly four times the half-precision throughput, which matters for AI inference and certain scientific workloads that rely on reduced-precision arithmetic.

Memory bandwidth tells a similar story. The Arc B770 features 16 GB of GDDR6 memory on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The RTX 1000 Mobile has 6 GB of GDDR6 on a 96-bit bus, giving 192.0 GB/s. That is a 2.67x advantage for the Intel card in raw memory throughput. For texture-heavy workloads, the Arc B770 posts a texture rate of 614.4 GTexel/s versus 162.0 GTexel/s for the NVIDIA part, a 3.79x margin. Pixel fill rates follow the same pattern: 307.2 GPixel/s for the Arc B770 against 97.20 GPixel/s for the RTX 1000, a 3.16x difference.

The shading resources on each chip reflect their intended roles. The Arc B770 carries 4096 shading units, 256 texture mapping units, and 128 raster operation units. The RTX 1000 Mobile has 2560 shading units, 80 TMUs, and 48 ROPs. The Intel part also includes 32 ray tracing cores, while the NVIDIA chip has 20 RT cores. However, the RTX 1000 Mobile brings 80 tensor cores to the table, a feature the Arc B770 does not list at all. That absence matters for applications that depend on NVIDIA's tensor-based acceleration paths.

Clock speeds favor the Intel card in both base and boost states. The Arc B770 runs at a 2100 MHz base and 2400 MHz boost, while the RTX 1000 Mobile operates at 1485 MHz base and 2025 MHz boost. The memory clock is identical at 2000 MHz with 16 Gbps effective data rate, but the wider bus on the Intel part turns that into far more usable bandwidth. The power envelope tells the other side of the story: the Arc B770 draws up to 225 W and requires a 550 W suggested power supply, while the RTX 1000 Mobile is rated at 35 W and uses no external power connectors. The NVIDIA chip is an integrated graphics processor (IGP) with a portable-device-dependent display output, whereas the Intel card is a dual-slot desktop board with one 6-pin and one 8-pin power connector.

The nearest rival data contains no entries for either product, and the benchmark arrays are empty. The percentile rankings place both at the 50th percentile against all GPUs in the database, but that figure appears to be a default assignment rather than a result of measured workloads. The wins counters are zero for both sides. The analysis therefore rests entirely on the specification-level comparisons, which consistently show the Arc B770 ahead in throughput, memory capacity, bandwidth, and fill rates, while the RTX 1000 Mobile leads in power efficiency and tensor core availability.

The Verdict

The data indicates two distinct purchasing decisions depending on the use case. The Intel Arc B770 is the stronger choice for desktop users who prioritize raw rendering performance, high-resolution textures, and compute throughput. Its 16 GB memory pool and 512.0 GB/s bandwidth make it suitable for large datasets and heavy rasterization workloads. The 39.32 TFLOPS FP16 figure gives it a substantial edge in half-precision compute tasks, and the 32 ray tracing cores provide dedicated hardware for ray-traced effects.

The NVIDIA RTX 1000 Mobile Ada Generation serves a different role entirely. Its 35 W power draw and IGP form factor make it appropriate for laptops and compact mobile workstations where energy consumption and thermal output are primary constraints. The 80 tensor cores are a notable advantage for applications that leverage NVIDIA's tensor operations, even though the overall FP32 and FP16 throughput is far lower than the Intel part. The 10.37 TFLOPS FP16 rating matches its FP32 output exactly, indicating no acceleration for reduced-precision workloads.

Neither product dominates across all categories. The Arc B770 wins every performance metric recorded in the database except tensor core count. The RTX 1000 Mobile wins on power efficiency, physical footprint, and tensor-specific features. A desktop workstation with unrestricted power budgets and a need for maximum throughput should favor the Arc B770. A mobile platform with limited cooling and battery considerations should favor the RTX 1000 Mobile. The choice is not about which is faster, but which fits the deployment environment.

Specification Differences

The two GPUs differ across nearly every specification field in the database. The Intel Arc B770 uses the BMG-G31 chip with the Xe2-HPG architecture, part of the Battlemage (Arc 7) generation. The NVIDIA RTX 1000 Mobile uses the AD107 chip with Ada Lovelace architecture, part of the Ada-MW (x000A) generation. The Intel part has a die size of 368 mm², while the NVIDIA chip measures 159 mm². Transistor counts are unknown for the Intel card, but the NVIDIA chip contains 18,900 million transistors with a density of 118.9M per mm².

Memory configurations diverge sharply. The Arc B770 offers 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth. The RTX 1000 Mobile has 6 GB of GDDR6 on a 96-bit bus with 192.0 GB/s bandwidth. Both use the same memory clock of 2000 MHz with a 16 Gbps effective rate. The Intel card includes 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. The NVIDIA chip has 2560 shading units, 80 TMUs, 48 ROPs, 20 RT cores, and 80 tensor cores. Pixel rates are 307.2 GPixel/s for the Arc B770 versus 97.20 GPixel/s for the RTX 1000. Texture rates are 614.4 GTexel/s versus 162.0 GTexel/s.

Power delivery separates the two entirely. The Arc B770 has a 225 W TDP, requires a dual-slot cooler, uses one 6-pin and one 8-pin power connector, and needs a 550 W suggested power supply. The RTX 1000 Mobile has a 35 W TDP, is an IGP with no power connectors, and has no suggested PSU rating. The bus interface differs as well: PCIe 4.0 x16 for the Intel part versus PCIe 4.0 x8 for the NVIDIA chip. Display outputs are also distinct: the Arc B770 provides one HDMI 2.1a and three DisplayPort 2.1 connections, while the RTX 1000 Mobile has a portable-device-dependent output.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates differ, with the NVIDIA part arriving earlier at 2024-02-25 and the Intel part dated 2025-12-31. The NVIDIA chip has an active production status and lists its predecessor as Ampere-MW and successor as Blackwell-MW. The Intel card lists Alchemist as its predecessor with no successor recorded.

Architecture Differences

The architectural philosophies behind these two chips are fundamentally different. The Intel Arc B770 uses the Xe2-HPG architecture, which is the second generation of Intel's high-performance graphics designs, succeeding Alchemist. The chip is built on a 5 nm process at TSMC and spans 368 mm². The NVIDIA RTX 1000 Mobile uses Ada Lovelace, which is NVIDIA's latest generation for mobile workstation parts, succeeding Ampere-MW and preceding Blackwell-MW. Its die is 159 mm², also on a 5 nm TSMC process, but with an explicit transistor count of 18,900 million and a density of 118.9M per mm².

The compute layout differs substantially. The Arc B770 allocates 4096 shading units across 256 TMUs and 128 ROPs, with 32 dedicated ray tracing cores. The RTX 1000 Mobile uses 2560 shading units across 80 TMUs and 48 ROPs, with 20 RT cores and 80 tensor cores. The tensor core count is the most significant architectural divergence, as the Intel part lists no equivalent hardware. This indicates that the NVIDIA chip incorporates dedicated AI acceleration hardware, while the Intel card relies on general-purpose shader execution for such tasks.

Memory subsystem architecture also separates the two. The Arc B770 connects to GDDR6 through a 256-bit interface, yielding 512.0 GB/s. The RTX 1000 Mobile uses a 96-bit interface to reach 192.0 GB/s. The wider interface on the Intel part allows it to sustain higher bandwidth despite identical memory clock speeds. The Arc B770's pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s are direct consequences of its larger ROP and TMU counts, which are 2.67x and 3.2x those of the NVIDIA chip, respectively.

The power architecture reflects their deployment targets. The Arc B770 is designed as a discrete desktop card with a 225 W TDP and external power connectors, indicating an expectation of a full-sized chassis with adequate cooling and a 550 W power supply. The RTX 1000 Mobile is an IGP with a 35 W TDP and no power connectors, built for portable systems where the CPU and GPU share thermal and power budgets. The clock behavior follows these constraints: the Intel part runs at 2100 MHz base and 2400 MHz boost, while the NVIDIA chip runs at 1485 MHz base and 2025 MHz boost. The lower clocks on the NVIDIA part are consistent with a power-limited mobile environment, while the Intel card's higher clocks take advantage of desktop-class power delivery.
