Z1 Extreme Chip: An Equivalence to Which GPU?

Introduction

The Z1 Extreme chip is a powerful integrated GPU that currently stands as the most advanced option for PCs. While there is no direct equivalent GPU, its performance closely matches that of lower-tier but still capable desktop graphics cards such as the GTX 1050 or RX 560. This chip can also be compared to low-powered versions of the GTX 1650 or high-powered versions of the MX450 laptop GPUs, as well as the graphical unit found in the PS4 Pro. This article delves into the performance benchmarking and practical comparisons of the Z1 Extreme chip.

Performance Comparison

Low Power Scenarios

In low-power scenarios where devices are constrained by power and high latency DDR5 memory, the Z1 Extreme chip is often compared to the GTX 1050 Ti or 1060 3GB, or the Radeon RX 570. A device running on power and limited DDR5-4800 memory might score around 2975 on the Time Spy GPU benchmark, while a more powerful system with unlimited power, fantastic cooling, and low-latency DDR5-5600 memory might achieve a score of around 3350.

These scores fall between the GTX 1050 Ti and GTX 1650 in specific benchmark scenarios. For instance, the GDDR6 GTX 1650 scores about 3589 on the Time Spy GPU benchmark, just ahead of the RX 470, which scores around 3510.

High Power Scenarios

When comparing the Z1 Extreme chip to other high-performance GPUs, the differences become more pronounced. Despite the Z1 Extreme/7840HS having 768 shaders similar to the 1050 Ti, its high clock speeds (up to 2800MHz) and architectural advantages can make it competitive in certain gaming scenarios. The Z1 Extreme chip, like the 780M, excels in compute-intensive games but may struggle in memory-intensive ones.

Specific Gaming Comparisons

Comparison with 1060 and 570

The Z1 is capable of matching the performance of the 570/1060 3GB in certain titles at certain resolutions and settings due to its high clock speeds and architectural advantages. However, the 1050 Ti, with 768 shaders, runs in-game at around 1875MHz, limiting its potential in terms of sustained performance and overclocking abilities.

Advantages and Disadvantages

The Radeon 780M, while having a slightly higher clock speed, loses out to the Z1 Extreme/7840HS in latency issues due to slower RAM speeds. The Z1/7840HS, being an 8-core Zen-4 processor, ensures that the CPU won't lag behind the GPU, providing a more balanced gaming experience.

Conclusion

In conclusion, while there is no direct equivalent to the Z1 Extreme chip, it falls into a competitive range compared to lower-tier but still capable desktop graphics cards like the GTX 1050 or RX 550. Its performance is comparable to mid-range GPUs such as the GTX 1650, and it performs admirably in compute-intensive games while maintaining a competitive edge in other scenarios.
