The future of the big apple looks promising, and A19 and A19 Pro surprise: chips are smaller than the A18 and still offer more performance and a larger GPU!
For those out of the loop, a brief context: Apple presented a significant evolution in its chipsets with the A19 series.
Unlike regular updates, new A19 and A19 Pro bring a series of improvements in relation to the A18 models of the previous generation.
One recent technical analysis indicates which chips equip the iPhone 17 line had a reduction in die area of ​​up to 10%.
However, before we proceed with more detailed explanations, check out a summary table with the main questions e answers on the topic:
| Question | Response |
|---|---|
| What is the main evolution of the A19 and A19 Pro chips? | They have a die area up to 10% smaller than the A18 generation, despite TSMC’s manufacturing process only allowing a 4% reduction. |
| How did Apple reduce the chip size so much? | With design innovations such as a more efficient layout of the SLC cache and blocks like the ISP, freeing up space for cores and GPU. |
| Are performance cores much more powerful? | They have a higher clock rate, but their size has decreased by 4%. The biggest gains are in the efficiency cores. |
| What has changed in the A19 Pro’s efficiency cores? | They had architectural changes that resulted in up to 29% more performance without a significant increase in consumption. |
| What is the practical result of these improvements? | The A19 Pro leads in performance per watt against chips like the Snapdragon 8 Elite Gen 5 and Dimensity 9500 in Geekbench 6. |
| Who makes these chips for Apple? | TSMC (Taiwan Semiconductor Manufacturing Company) manufactures the A19 and A19 Pro chips on its 3nm process (N3P). |
| And what’s next with the A20 chips? | The next generation, A20 and A20 Pro, are expected to be manufactured on TSMC’s 2nm process, promising new advances. |
How Apple achieved a greater area reduction than the manufacturing process
Returning to the main theme, the TSMCan Apple supplier, with its new 3nm N3P process makes it possible to reduce the area by 4% compared to N3E, also 3nm.
However, Apple engineers achieved a 9% to 10% decrease in the new chips. This was made possible through innovations in internal design.
The report of the SemiAnalysis (shared above) details that, although the SLC cache stay in 4MBits implementation in A19 occupies 0.98 mm²contra 1,08 mm² no A18. The reorganization of blocks such as the image signal processor and media engine freed up space for other components.
Revamped architecture prioritizes efficiency and GPU cores
A redistribution of internal area It mainly benefited the efficiency cores and the graphics processing unit. Us A19 and A19 Pro modelsthe performance cores operate at a higher clock rate, but have had their size reduced by 4%.
The biggest change occurred in A19 Pro efficiency coreswho passed through profound architectural changes. These changes resulted in a performance gain of up to 29% without a significant increase in energy consumption.
Practical results and leadership in performance per watt
These advancements give the A19 Pro a advantage in multi-core benchmarks. The energy efficiency achieved positions Apple’s chipset with performance metrics per watt superior to those of current competitors, such as Snapdragon 8 Elite Gen 5 and Qualcomm and the Dimensity 9500 and MediaTekin tests such as Geekbench 6.
Design optimization, therefore, brought notable gains in both power of processing as in autonomy.

A19 and A19 Pro are surprising: chips are smaller than the A18; conclusions on the future of 2nm lithography
The trajectory of innovation should continue with the next generation. It is anticipated that the future A20 chips e A20 Pro from Apple are manufactured on TSMC’s new 2nm process.
To finishwe highlight that this migration should allow new technological leaps, driven by more advanced lithography and other design improvements.
The same design approach should be applied to next generation Mac chipso M6planned for the new models of the MacBook Pro.
