AMD Ryzen Z1 GPU vs Intel Arc G3 Extreme Comparison

The Verdict

The database records two very different mobile graphics solutions. The AMD Ryzen Z1 GPU is a compact, low-power integrated part built on TSMC's 4 nm process, designed to fit into small consoles or handhelds. The Intel Arc G3 Extreme is a far larger and more capable integrated graphics processor, built on Intel's 3 nm process and intended to power high-end portable devices. The data clearly shows the Intel part is the performance leader, delivering 3.0x the FP32 throughput of the AMD part, with a higher pixel rate and texture rate. However, the AMD part operates at a much lower power envelope, using 30 W compared to the Intel part's 80 W. The choice between them depends entirely on the target device's power budget and performance needs. For a fanless or battery-constrained handheld where efficiency is paramount, the AMD Ryzen Z1 GPU is the logical pick. For a device with active cooling and a larger battery, the Intel Arc G3 Extreme offers a substantial performance advantage.

Architecture Differences

The AMD Ryzen Z1 GPU uses the Phoenix chip and is built on the RDNA 3.0 architecture. It is manufactured by TSMC on a 4 nm process node. The chip contains 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6 million per square millimeter. The Intel Arc G3 Extreme uses the Panther Lake chip and is built on the Xe3-LPG architecture. It is manufactured by Intel on a 3 nm process node. The database does not record the transistor count or die size for the Intel part.

The two parts differ significantly in their core configurations. The AMD Ryzen Z1 GPU has 256 shading units, 16 texture mapping units (TMUs), and 8 raster output units (ROPs). It also has 4 ray tracing cores. The Intel Arc G3 Extreme has 1536 shading units, 48 TMUs, and 24 ROPs. It has 12 ray tracing cores. This means the Intel part has 6.0x the shading units, 3.0x the TMUs, and 3.0x the ROPs compared to the AMD part. The Intel part also has 3.0x the ray tracing cores.

Memory configurations also differ. The AMD Ryzen Z1 GPU has 16 GB of dedicated LPDDR5 memory with a 64-bit bus width and a bandwidth of 51.20 GB/s. The Intel Arc G3 Extreme uses system shared memory, with its size, type, and bus width all being system dependent. The database does not record a dedicated bandwidth for the Intel part; instead, it is listed as system dependent. The AMD part's memory clock is 800 MHz, which translates to 6.4 Gbps effective. The Intel part's memory clock is listed as "System Shared".

Feature support is similar. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part has no display outputs, while the Intel part's display outputs are listed as "Portable Device Dependent". The AMD part has a 280 mm length, 111 mm height, and 21 mm width. The Intel part has no recorded dimensions, as it is an integrated graphics processor (IGP). The Intel part has a slot width of "IGP" and a bus interface of "IGP", while the AMD part does not record a bus interface. Neither part requires a power connector.

Head-to-Head Benchmarks

The database does not include any direct head-to-head benchmark results for these two parts. The benchmarks array is empty for both, and the wins count is zero for each. However, the recorded specification data allows for a meaningful comparison of their theoretical peak performance. The Intel Arc G3 Extreme delivers 7.680 TFLOPS of FP32 compute, which is exactly 3.0x the 2.560 TFLOPS delivered by the AMD Ryzen Z1 GPU. In FP16, the Intel part delivers 15.36 TFLOPS (2:1), which is also 3.0x the AMD part's 5.120 TFLOPS (2:1).

The pixel rate and texture rate follow a similar pattern. The Intel Arc G3 Extreme achieves a pixel rate of 60.00 GPixel/s, which is 3.0x the AMD part's 20.00 GPixel/s. The Intel part achieves a texture rate of 120.0 GTexel/s, which is 3.0x the AMD part's 40.00 GTexel/s. These ratios are consistent across all compute and rasterization metrics, indicating that the Intel part is a uniform 3.0x scaling of the AMD part in terms of raw throughput.

Clock speeds tell a more nuanced story. Both parts have the same 2500 MHz boost clock. The AMD part has a base clock of 1500 MHz, while the Intel part has a much lower base clock of 300 MHz. The AMD part's higher base clock means it can maintain a higher minimum performance level. However, the Intel part's massive core count advantage (1536 vs 256 shading units) means that even at a lower base clock, it can still deliver far more aggregate compute when boosted. The AMD part's memory bandwidth of 51.20 GB/s is a fixed figure, while the Intel part's bandwidth is system dependent, meaning the actual achievable bandwidth will vary based on the host device's memory configuration.

FAQ

Q: Which part has higher raw compute performance?

A: The Intel Arc G3 Extreme has significantly higher raw compute performance. It delivers 7.680 TFLOPS of FP32, which is exactly 3.0x the 2.560 TFLOPS delivered by the AMD Ryzen Z1 GPU. The same 3.0x ratio applies to FP16 performance, with the Intel part delivering 15.36 TFLOPS versus the AMD part's 5.120 TFLOPS.

Q: What is the power consumption difference?

A: The AMD Ryzen Z1 GPU has a TDP of 30 W, while the Intel Arc G3 Extreme has a TDP of 80 W. The Intel part consumes 2.67x the power of the AMD part. This is a substantial difference that affects cooling requirements and battery life.

Q: How do their memory configurations compare?

A: The AMD Ryzen Z1 GPU uses 16 GB of dedicated LPDDR5 memory with a 64-bit bus and 51.20 GB/s bandwidth. The Intel Arc G3 Extreme uses system shared memory, with no dedicated VRAM. Its memory size, type, and bus width are all system dependent, as is its bandwidth.

Q: Which part has more ray tracing cores?

A: The Intel Arc G3 Extreme has 12 ray tracing cores, which is 3.0x the 4 ray tracing cores found in the AMD Ryzen Z1 GPU. This suggests the Intel part has a higher capacity for ray tracing workloads.

Q: Are there any display output differences?

A: Yes. The AMD Ryzen Z1 GPU has no display outputs, meaning it cannot drive a display directly. The Intel Arc G3 Extreme has display outputs that are listed as "Portable Device Dependent", meaning its display capabilities depend on the host portable device.

Where Each One Wins

The AMD Ryzen Z1 GPU wins in power efficiency. Its 30 W TDP is the clear advantage. For a handheld console or a compact device where battery life and heat dissipation are critical, this part is the better fit. Its dedicated 16 GB of LPDDR5 memory with 51.20 GB/s bandwidth provides a fixed, predictable memory subsystem that does not depend on the host system. Its higher base clock of 1500 MHz also means it maintains a more consistent performance floor, even before boosting to its 2500 MHz maximum.

The Intel Arc G3 Extreme wins decisively in raw performance. Its 3.0x advantage in FP32 throughput, pixel rate, and texture rate makes it the clear choice for demanding workloads. The 1536 shading units, 48 TMUs, and 24 ROPs provide substantial rasterization capacity. Its 12 ray tracing cores give it 3.0x the ray tracing hardware of the AMD part. For a device with active cooling and a robust power delivery system, this part delivers a much higher level of graphical fidelity and frame rates. Its system shared memory architecture means it can potentially access a larger pool of memory, though the actual bandwidth will depend on the host device's memory subsystem.

The choice ultimately comes down to the device's design goals. A device prioritizing portability, low heat, and long battery life should use the AMD Ryzen Z1 GPU. A device prioritizing maximum graphical performance in a larger form factor should use the Intel Arc G3 Extreme.
