Analysis: AMD Radeon 760M vs Intel Arc B770
The Verdict
The database places these two products in entirely different segments. The AMD Radeon 760M is an integrated graphics processor (IGP) designed for low-power Phoenix-based laptops, sitting in the 35th percentile of all GPUs with an average benchmark score of 6019. The Intel Arc B770 is a dual-slot discrete desktop graphics card based on the Battlemage architecture, occupying the 50th percentile of all GPUs, though it currently has no recorded benchmark scores in the database. The Radeon 760M is best suited for light gaming and everyday computing in thin-and-light systems where its 15 W TDP and integrated design fit naturally. The Arc B770 targets high-refresh-rate 1080p and 1440p gaming, with 16 GB of dedicated GDDR6 memory and a 225 W TDP that requires a 550 W suggested power supply. The data shows no direct head-to-head matchups, so the comparison relies on architectural and specification differences rather than recorded benchmark deltas.
Where Each One Wins
The AMD Radeon 760M wins in power efficiency and system integration. Its 15 W TDP allows it to operate without any power connectors, drawing everything from the motherboard. The 760M uses system-shared memory, meaning the system's RAM serves as both its framebuffer and bandwidth source, which simplifies the laptop design and reduces cost. Its PCIe 4.0 x8 interface provides adequate bandwidth for an integrated solution. The 760M also carries a production status of Active, indicating it is currently in the market.
The Intel Arc B770 wins decisively in raw performance potential. Its 4096 shading units, 256 texture mapping units, and 128 render output units dwarf the 760M's 512 shading units, 32 TMUs, and 16 ROPs. The B770's 19.66 TFLOPS FP32 throughput is roughly 3.7 times the 760M's 5.323 TFLOPS. The B770 also has dedicated 16 GB GDDR6 memory on a 256-bit bus delivering 512.0 GB/s of bandwidth, whereas the 760M's memory bandwidth is system dependent. The B770's 32 ray tracing cores versus the 760M's 8 RT cores gives it a substantial advantage in ray-traced workloads. The B770 also provides four display outputs (one HDMI 2.1a and three DisplayPort 2.1), while the 760M's outputs are motherboard dependent.
Architecture Differences
The two chips come from different foundries, process nodes, and design philosophies. The AMD Radeon 760M uses the Phoenix chip built on RDNA 3.0 architecture, manufactured on a 4 nm process at TSMC with 25,390 million transistors on a 178 mm² die. This yields a transistor density of 142.6 million per square millimeter. The 760M is part of the Navi III IGP generation, classified as a direct successor to the Navi II IGP line.
The Intel Arc B770 uses the BMG-G31 chip based on Xe2-HPG architecture, manufactured on a 5 nm process at TSMC. Its die size is 368 mm², more than double the 760M's die area. Intel does not disclose the transistor count for this chip, and no transistor density is recorded. The B770 belongs to the Battlemage (Arc 7) generation, with the Alchemist architecture as its predecessor.
Clock behavior differs substantially. The 760M has a base clock of 800 MHz and a boost clock of 2599 MHz, a wide boost range typical of integrated parts that scale with thermal headroom. The B770 runs a base clock of 2100 MHz and a boost clock of 2400 MHz, a narrower range that reflects a desktop part already running near its limits. The B770's memory clock is 2000 MHz with 16 Gbps effective speed, while the 760M's memory clock is system shared and dependent on the host system's RAM.
Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 760M's FP16 performance matches its FP32 at 5.323 TFLOPS (1:1 ratio), whereas the B770 doubles its FP16 throughput to 39.32 TFLOPS (2:1 ratio), indicating better utilization of its compute units for FP16 workloads.
FAQ
Q: Which GPU has higher raw compute throughput?
A: The Intel Arc B770 delivers 19.66 TFLOPS FP32 performance, which is approximately 3.7 times the AMD Radeon 760M's 5.323 TFLOPS. In FP16 workloads, the gap widens further: the B770 reaches 39.32 TFLOPS versus the 760M's 5.323 TFLOPS.
Q: How does memory configuration affect these two GPUs?
A: The Arc B770 includes 16 GB of dedicated GDDR6 memory on a 256-bit bus with 512.0 GB/s bandwidth. The Radeon 760M uses system shared memory with system dependent bandwidth, so its performance scales with the host system's RAM speed and configuration.
Q: What power delivery does each GPU require?
A: The Radeon 760M operates at 15 W TDP with no power connectors and an integrated form factor. The Arc B770 runs at 225 W TDP, requires one 6-pin and one 8-pin power connector, is dual-slot in size, and needs a 550 W suggested power supply.
Q: Which GPU supports ray tracing?
A: Both GPUs support ray tracing. The Arc B770 includes 32 ray tracing cores, while the Radeon 760M includes 8 RT cores. The B770's higher RT core count suggests substantially better ray tracing performance, though no direct benchmark data confirms this.
Q: What are the display output capabilities?
A: The Arc B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The Radeon 760M's display outputs are motherboard dependent, meaning the laptop or board manufacturer determines what ports are available.

A: The Radeon 760M released on January 30, 2024 and remains in Active production. The Arc B770 has a release date of December 31, 2025, and its production status is not recorded in the database.
Head-to-Head Benchmarks
The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 760M and Intel Arc B770. The 760M has ten recorded benchmark scores, while the B770 has none. This absence of direct measurement data means the comparison must rest on the architectural and specification differences.
The 760M's recorded scores show its performance profile. In 3DMark Steel Nomad DX12, it scores 400. Geekbench OpenCL returns 20255, and Geekbench Vulkan returns 30336. Passmark results are mixed: DirectX 10 scores 19, DirectX 11 scores 52, DirectX 12 scores 25, DirectX 9 scores 65, G2D scores 890, G3D scores 5310, and GPU compute scores 2840. The average benchmark score across all tests is 6019, placing it in the 35th percentile of all GPUs.
The nearest rivals to the 760M provide context for its performance tier. The AMD Radeon RX 6400 scores 6001, a 0.3 percent delta from the 760M's 6019 average. The NVIDIA GeForce GTX 770M also scores 6000, another 0.3 percent delta. The NVIDIA RTX PRO 6000 Blackwell Server scores 5996, a 0.4 percent delta. The NVIDIA Quadro P2000 scores 6049, which is 0.5 percent higher than the 760M. These tight margins show the 760M sits squarely in a performance band around 6000 average benchmark points, roughly matching entry-level discrete GPUs from several generations ago.
The Arc B770's lack of recorded benchmarks means its nearest rivals list is empty and its average benchmark score is 0. The database does show its percentile ranking at 50, which places it above the 760M's 35th percentile, but without actual scores this ranking cannot be verified against measured data. The B770's theoretical specifications suggest it should far exceed the 760M's scores, but the database cannot confirm this with recorded numbers.
