AMD Ryzen Z1 Extreme GPU vs Intel Arc B370 Comparison

The Verdict

The recorded data shows two fundamentally different products that serve distinct roles. The AMD Ryzen Z1 Extreme GPU is a console-class integrated graphics solution built on the Phoenix chip, while the Intel Arc B370 is an integrated graphics processor belonging to the Panther Lake generation. The database contains no direct head-to-head benchmark results between these two parts, and the AMD Ryzen Z1 Extreme GPU has no recorded benchmark scores or nearest rivals listed. The Intel Arc B370, however, has one benchmark entry: a 3DMark Steel Nomad DX12 score of 1184.

Based strictly on the available information, the AMD Ryzen Z1 Extreme GPU holds a significant theoretical advantage. It delivers 8.294 TFLOPS of FP32 compute, which is 35% higher than the Intel Arc B370's 6.144 TFLOPS. The AMD part also features a higher boost clock of 2700 MHz against Intel's 2400 MHz, and it operates at a 30 W TDP compared to Intel's 25 W. The AMD solution uses 16 GB of dedicated LPDDR5 memory with 51.20 GB/s of bandwidth, whereas the Intel part relies on system shared memory with system-dependent bandwidth. For users who need a self-contained graphics solution with dedicated memory, the AMD Ryzen Z1 Extreme GPU is the clear choice from the data. The Intel Arc B370, built on Intel's 3 nm process, offers a lower power envelope and is positioned for portable devices, but its single benchmark score places it in the 5th percentile among all GPUs, indicating modest absolute performance.

Where Each One Wins

The AMD Ryzen Z1 Extreme GPU wins on raw compute throughput. Its FP32 performance of 8.294 TFLOPS outpaces the Intel Arc B370's 6.144 TFLOPS, a margin of roughly 35%. The AMD part also produces a higher pixel rate of 86.40 GPixel/s versus Intel's 48.00 GPixel/s, and a superior texture rate of 129.6 GTexel/s versus 96.00 GTexel/s. The AMD GPU has 768 shading units, 48 texture mapping units, and 32 raster operation units, compared to Intel's 1280 shading units, 40 TMUs, and 20 ROPs. Interestingly, Intel fields more shading units but fewer TMUs and ROPs, which explains the AMD advantage in fillrate metrics.

The Intel Arc B370 wins on power efficiency and process technology. It uses a 3 nm process from Intel's own foundry, while the AMD Phoenix chip uses TSMC's 4 nm process. The Intel part draws 25 W against AMD's 30 W, a 17% reduction in TDP. The Intel GPU also has a lower base clock of 300 MHz compared to AMD's 800 MHz, allowing it to idle or run at very low power states when demand is minimal. The Intel Arc B370's release date of 2026-01-26 makes it a newer design than the AMD part, which launched on 2023-06-12. For thermally constrained portable devices, the Intel part's lower power draw and newer node offer a power efficiency advantage.

In ray tracing, the AMD Ryzen Z1 Extreme GPU carries 12 ray tracing cores, while the Intel Arc B370 has 10. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part's higher RT core count suggests a potential lead in ray-traced workloads, though no direct benchmark data confirms this.

Architecture Differences

The AMD Ryzen Z1 Extreme GPU is based on the RDNA 3.0 architecture, implemented on the Phoenix chip. It uses TSMC's 4 nm process and integrates 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million transistors per square millimeter. The Intel Arc B370 uses the Xe3-LPG architecture on the Panther Lake chip, fabricated on Intel's 3 nm process. Intel's transistor count and die size are listed as unknown in the database, so no density comparison is possible.

Memory architecture differs fundamentally. The AMD part uses 16 GB of LPDDR5 memory on a 64-bit bus, providing a fixed bandwidth of 51.20 GB/s. The Intel Arc B370 uses system shared memory, meaning its bus width, memory type, and bandwidth are all system dependent. This makes the AMD solution more predictable in performance, while the Intel part's performance varies with the host system's memory configuration.

Clock behavior also differs. The AMD Ryzen Z1 Extreme GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, with memory clocked at 800 MHz or 6.4 Gbps effective. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with system shared memory. The AMD part's higher base clock suggests it maintains higher performance even under sustained loads, while Intel's lower base clock allows deeper power saving states.

The physical specifications reflect their intended use cases. The AMD Ryzen Z1 Extreme GPU is a discrete-style component measuring 280 mm in length, 111 mm in height, and 21 mm in width, with a single USB Type-C display output. The Intel Arc B370 is an integrated graphics processor (IGP) with no dimensions listed, no power connectors, and display outputs that are portable device dependent. The AMD part has no power connectors either, relying on the 30 W TDP budget. The Intel part's 25 W TDP and IGP form factor make it suitable for compact, low-power portable systems.

Both GPUs support identical API feature sets: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores listed. The AMD part's launch MSRP was 699 USD, while the Intel part has no launch MSRP recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen Z1 Extreme GPU and the Intel Arc B370. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. However, the available specifications allow a quantitative comparison of theoretical performance ceilings.

The most significant advantage for the AMD Ryzen Z1 Extreme GPU is in FP32 compute. At 8.294 TFLOPS, it outperforms the Intel Arc B370's 6.144 TFLOPS by 2.15 TFLOPS, a 35% lead. This translates directly to higher shader throughput in compute-heavy workloads. The AMD part's pixel rate of 86.40 GPixel/s is 80% higher than Intel's 48.00 GPixel/s, meaning the AMD GPU can fill the screen with rendered pixels faster at high resolutions. Its texture rate of 129.6 GTexel/s is 35% higher than Intel's 96.00 GTexel/s, which benefits texture-heavy scenes.

The Intel Arc B370 counters with a lower TDP of 25 W versus 30 W, a 17% reduction. It also uses a smaller 3 nm process node, though Intel's transistor count and die size are unknown, so the density comparison cannot be quantified. The Intel part has more shading units (1280 versus 768), but fewer TMUs (40 versus 48) and ROPs (20 versus 32). This configuration explains why Intel's fillrate metrics lag despite a higher shader count.

In ray tracing, the AMD Ryzen Z1 Extreme GPU features 12 RT cores versus Intel's 10, a 20% advantage in dedicated ray tracing hardware. Both GPUs support DirectX 12 Ultimate, so ray-traced games can run on either, but the AMD part's higher RT core count suggests it may handle ray tracing workloads more efficiently.

Memory bandwidth is another area of clear differentiation. The AMD part's dedicated 51.20 GB/s of LPDDR5 bandwidth is fixed and predictable. The Intel Arc B370's bandwidth is system dependent, so it could be higher or lower depending on the host platform's memory speed and channel configuration. In a best-case scenario with fast system memory, the Intel part might close the gap, but its performance remains contingent on the surrounding hardware.

The Intel Arc B370's single recorded benchmark score of 1184 in 3DMark Steel Nomad DX12 places it at the 5th percentile among all GPUs. Its nearest rivals, all with scores within 1.4% of its result, include the ATI Mobility Radeon HD 5570 (1186), ATI Radeon HD 5770 (1190), AMD Radeon HD 7650M (1192), and AMD FirePro M2000 (1168). This cluster of scores indicates that the Intel Arc B370 performs at a level comparable to older entry-level discrete GPUs, despite its modern 3 nm process and Xe3-LPG architecture.

The AMD Ryzen Z1 Extreme GPU has no benchmark scores or nearest rivals in the database, and its percentile rank is 50, exactly the median. This lack of recorded data means its real-world performance cannot be positioned relative to other GPUs using benchmark results. The specifications alone, however, point to a substantially more capable graphics solution. Its higher TFLOPS, faster fillrates, dedicated memory, and larger RT core count all favor the AMD part in raw performance terms.

For users prioritizing performance, the AMD Ryzen Z1 Extreme GPU is the stronger choice based on compute throughput, memory bandwidth, and fillrate. For users prioritizing power efficiency and the smallest possible footprint, the Intel Arc B370's 25 W TDP, 3 nm process, and IGP form factor make it an attractive option for ultraportable devices. The data does not show a direct performance comparison, but the specification sheet gives the AMD part a decisive lead in most measurable graphics metrics.
