AMD Ryzen Z1 Extreme GPU vs Intel Arc B770 Comparison

FAQ

Q: What are the two products compared here?

A: The AMD Ryzen Z1 Extreme GPU, a console-class integrated graphics solution built on the RDNA 3.0 architecture, and the Intel Arc B770, a discrete desktop graphics card based on the Xe2-HPG architecture from the Battlemage (Arc 7) generation.

Q: How do their memory subsystems differ?

A: The AMD Ryzen Z1 Extreme GPU uses 16 GB of LPDDR5 memory on a 64-bit bus, delivering 51.20 GB/s of bandwidth. The Intel Arc B770 also has 16 GB, but it is GDDR6 on a 256-bit bus, yielding 512.0 GB/s, which is ten times higher bandwidth.

Q: What are the process nodes and die sizes?

A: The AMD chip is built on TSMC's 4 nm process with a die size of 178 mm² and 25,390 million transistors, giving a density of 142.6M per mm². The Intel Arc B770 uses TSMC's 5 nm node with a die size of 368 mm²; its transistor count is listed as unknown in the database.

Q: Which GPU has higher clock speeds?

A: The Intel Arc B770 has a base clock of 2100 MHz and a boost clock of 2400 MHz. The AMD Ryzen Z1 Extreme GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, so AMD boosts higher but starts much lower.

Q: What are the power requirements for each?

A: The AMD Ryzen Z1 Extreme GPU has a TDP of 30 W and uses no power connectors. The Intel Arc B770 has a TDP of 225 W, requires a 550 W suggested PSU, and uses one 6-pin plus one 8-pin power connector.

Q: Which GPU has higher raw compute throughput?

A: The Intel Arc B770 delivers 19.66 TFLOPS of FP32 compute and 39.32 TFLOPS of FP16 (2:1). The AMD Ryzen Z1 Extreme GPU delivers 8.294 TFLOPS of FP32 and 16.59 TFLOPS of FP16 (2:1), meaning Intel has roughly 2.4 times the FP32 throughput.

Where Each One Wins

The data splits clearly by workload category. The AMD Ryzen Z1 Extreme GPU wins in scenarios where power efficiency and compact integration matter most. Its 30 W TDP and 178 mm² die size make it suitable for constrained environments, especially portable console-class designs. The absence of external power connectors and a single USB Type-C display output reinforce that positioning. The Intel Arc B770, by contrast, is a full-sized dual-slot desktop card with PCIe 4.0 x16 interface, three DisplayPort 2.1 outputs, one HDMI 2.1a output, and a 225 W TDP, making it a dedicated add-in board for desktop systems.

For memory-sensitive workloads, the Intel Arc B770 wins decisively. Its 512.0 GB/s bandwidth is an order of magnitude higher than the AMD part's 51.20 GB/s. Any application that streams large textures, performs heavy data movement, or relies on rapid buffer access will favor the Intel card. The AMD GPU's 64-bit memory bus limits its ability to feed its shading units at high throughput, even though its boost clock reaches 2700 MHz.

Compute-heavy tasks also favor Intel. The Arc B770 has 4096 shading units, 256 texture mapping units, and 128 ROPs, versus 768, 48, and 32 respectively for the AMD part. The Intel card's FP32 throughput of 19.66 TFLOPS versus 8.294 TFLOPS gives it a clear lead in general-purpose GPU compute. Ray tracing workloads follow the same pattern, with Intel having 32 ray tracing cores versus AMD's 12.

The AMD Ryzen Z1 Extreme GPU does win on transistor density and process technology. Its 4 nm node and 142.6M transistors per mm² indicate a more advanced manufacturing process than the 5 nm node used by Intel. For systems where physical space and power draw are the primary constraints, AMD's design is the better fit. The Intel Arc B770 also has a later release date of 2025-12-31 versus 2023-06-12 for AMD, but the database shows both at the 50th percentile among all GPUs, indicating comparable overall standing in the broader performance distribution.

Architecture Differences

The AMD Ryzen Z1 Extreme GPU uses the RDNA 3.0 architecture on the Phoenix chip. It is classified as a Console GPU generation from AMD. The Intel Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, belonging to the Battlemage (Arc 7) generation. These are fundamentally different design philosophies: AMD's RDNA 3.0 is a streamlined graphics architecture optimized for integration, while Intel's Xe2-HPG is a high-throughput discrete architecture.

Process technology differs. AMD is on TSMC's 4 nm node with 25,390 million transistors on a 178 mm² die. Intel is on TSMC's 5 nm node with a 368 mm² die, though its transistor count is unknown in the database. The AMD part achieves a transistor density of 142.6M per mm², while the Intel part's density is not recorded. The smaller die and higher density for AMD suggest a more tightly packed design, while Intel's larger die allows for more physical hardware units.

Core counts diverge sharply. AMD has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. Intel has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. Intel's core configuration is roughly five times larger in shading units and TMUs, and four times larger in ROPs. Ray tracing core count is 2.7 times higher on Intel.

Memory architecture is another fundamental split. AMD pairs its 64-bit bus with LPDDR5 memory at 6.4 Gbps effective, yielding 51.20 GB/s. Intel uses a 256-bit bus with GDDR6 at 16 Gbps effective, yielding 512.0 GB/s. The memory type difference (LPDDR5 versus GDDR6) reflects their intended use cases: integrated mobile/console versus discrete desktop.

The API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with AMD offering a single USB Type-C port and Intel providing one HDMI 2.1a and three DisplayPort 2.1 outputs. Power delivery also differs: AMD has no power connectors and a 30 W TDP, while Intel uses one 6-pin and one 8-pin connector with a 225 W TDP and a 550 W suggested PSU.

Specification Differences

Head-to-Head Benchmarks

The database shows no direct head-to-head benchmark entries between the AMD Ryzen Z1 Extreme GPU and the Intel Arc B770. However, the recorded specifications allow for direct quantitative comparison across every major performance metric.

The largest win for Intel is memory bandwidth. Intel's 512.0 GB/s is exactly ten times the AMD part's 51.20 GB/s. This is the single biggest proportional gap in the comparison. It means Intel can feed its 4096 shading units at a rate AMD cannot approach, which directly impacts texture-heavy rendering and high-resolution workloads.

In pixel throughput, Intel delivers 307.2 GPixel/s versus AMD's 86.40 GPixel/s, a 3.56 times advantage. Texture rate shows Intel at 614.4 GTexel/s versus AMD's 129.6 GTexel/s, a 4.74 times advantage. These ratios indicate that Intel's rasterization pipeline has substantially more fill rate capacity.

Compute throughput follows the same pattern. Intel's FP32 of 19.66 TFLOPS is 2.37 times AMD's 8.294 TFLOPS. FP16 (2:1) shows Intel at 39.32 TFLOPS versus AMD's 16.59 TFLOPS, a 2.37 times ratio as well. The consistency of these ratios suggests the architecture scales uniformly across precision formats.

Shader core count gives Intel a 5.33 times advantage (4096 versus 768), while TMU count is 5.33 times higher (256 versus 48) and ROP count is 4 times higher (128 versus 32). Ray tracing cores are 2.67 times higher on Intel (32 versus 12). These raw unit counts explain the throughput deltas.

AMD's counterpoints are clock speed and process node. AMD's boost clock of 2700 MHz exceeds Intel's 2400 MHz by 300 MHz, a 12.5% advantage. This partially compensates for the lower core count at the architectural level, but the sheer scale of Intel's core array overwhelms the clock advantage. AMD's 4 nm node versus Intel's 5 nm node gives AMD a process generation lead, reflected in its 142.6M transistors per mm² density, though Intel's larger die compensates with more absolute resources.

The TDP difference is stark: 30 W for AMD versus 225 W for Intel, a 7.5 times gap. This means Intel consumes substantially more power to achieve its performance figures, while AMD delivers its compute within a fraction of the power envelope. The performance-per-watt dynamic strongly favors AMD, though the database does not record direct efficiency benchmarks.

Both GPUs sit at the 50th percentile among all GPUs in the database, indicating that despite their massive specification differences, they occupy a similar overall standing in the broader GPU population. The launch MSRP of 699 USD for the AMD part, with no MSRP recorded for Intel, is the only pricing data available, and it is listed solely as a factual data point.

The release timeline shows AMD arriving on 2023-06-12 and Intel on 2025-12-31, a gap of roughly two and a half years. Intel's predecessor is listed as Alchemist, indicating a generational progression, while AMD's entry has no predecessor or successor recorded. The production status for AMD is Active; Intel's status is not recorded in the database.
