Apple A20 Pro Benchmark Comparison: What Early 2nm iPhone Results Actually Show

Apple’s A20 Pro is Apple’s first 2nm iPhone chip, powering the iPhone 18 Pro, iPhone 18 Pro Max and iPhone Duo. The first Geekbench database entries suggest a meaningful leap in peak CPU performance and an especially large graphics gain. The important qualification: early benchmark listings measure short bursts, not the heat, battery draw and frame-rate stability that determine performance in real games and video workloads. 149

The headline A20 Pro results

A likely iPhone 18 Pro Max entry identified as iPhone19,3 recorded 4,725 single-core and 12,575 multi-core in Geekbench. A separate Geekbench Metal run recorded 64,069. The chip is listed with a six-core CPU in a 2+4 arrangement, and reports place its two performance cores at about 4.93GHz. 9

Benchmark	Reported A20 Pro score	What it primarily indicates
Geekbench single-core	4,725	Peak speed in lightly threaded work
Geekbench multi-core	12,575	Throughput when software uses all CPU cores
Geekbench Metal	64,069	Apple-platform GPU compute/graphics performance

Single-core performance is most relevant to short, responsive tasks that cannot spread well across many cores. Multi-core performance matters more for heavily parallel work. Neither figure directly tells a buyer how much faster every app will feel, and Metal is not a valid score for comparing an iPhone GPU directly with Android GPUs.

How A20 Pro compares with A19 Pro

Early reporting puts the A20 Pro roughly 21%–23% ahead in single-core and 27%–28% ahead in multi-core Geekbench performance versus A19 Pro. 4 Apple says the A20 Pro has a six-core CPU, seven-core GPU and 32-core Neural Engine, and claims up to 40% faster sustained performance than A19 Pro. That is Apple’s claim, not yet an independent stress-test result. 6

The reported 64,069 Metal result is about 37.1% above a cited A19 Pro Metal result of 46,725. This is a large apparent generational GPU increase, but it should not be attributed solely to the 2nm process: A20 Pro also moves to a seven-core GPU configuration. 16

In practical terms, the GPU result suggests more headroom for demanding games, video effects and graphics-heavy processing. It does not prove that an iPhone will maintain that advantage after a long gaming session.

A20 Pro vs. Xiaomi Xring O3

Reported Geekbench 6 results for Xiaomi’s 10-core Xring O3 are 3,854 single-core and 15,086 multi-core. 1926 Using those figures:

• A20 Pro’s 4,725 single-core result is about 22.6% higher.
• A20 Pro’s 12,575 multi-core result is about 16.6% lower.

That split is consistent with a chip designed around a higher core count achieving stronger all-core throughput while Apple retains a very high single-core result. Still, this is not a final winner-and-loser verdict. The Xring figures have been reported from reference hardware, and benchmark versions, device cooling, power settings and test conditions can materially change the outcome. 2628

What about Snapdragon 8 Elite Extreme Gen 6 and Dimensity 9600 Pro?

The available Snapdragon and Dimensity figures remain leak-based, inconsistent and tied to pre-release hardware. One early Snapdragon 8 Elite Extreme Gen 6 listing reported 3,434 single-core and 9,334 multi-core, while an earlier Dimensity 9600 listing reported 2,653 and 7,516 respectively. 27 A later report cited a Dimensity 9600 Pro result of 4,137 single-core and 12,751 multi-core, illustrating why it is too early to assign a durable ranking. 30

Reports also describe the presumed Snapdragon 8 Elite Gen 6 Pro and Dimensity 9600 Pro as TSMC N2P designs. If those claims prove correct, Apple’s exclusive advantage from reaching 2nm first would narrow at the manufacturing-process level. Process technology is only one part of the result, however: CPU design, GPU architecture, memory bandwidth, software drivers, device cooling and power tuning all affect real-world performance. 21

Why the cooling system matters as much as the benchmark

Apple is pairing A20 Pro with a vapor-chamber cooling system. Reuters reported that Apple says this combination is designed to support demanding workloads, while Apple’s stated sustained-performance claim reaches up to 40% over A19 Pro. 16

That matters because a phone’s peak benchmark is only the opening condition. Under extended gaming, recording, rendering or AI workloads, the device must move heat away from the chip or reduce clocks to control temperature. A better thermal path should delay or lessen throttling, but it cannot eliminate thermal limits in a thin sealed phone.

The evidence still needed is straightforward: independent sustained benchmark loops, game frame-rate logs, surface-temperature measurements and power-draw data from retail devices. Until those arrive, the strongest conclusion is that A20 Pro looks extremely fast in short tests and that Apple has made a credible architectural and thermal push to preserve more of that speed under load.

Why Metal cannot settle the Android GPU race

Geekbench Metal uses Apple’s Metal API. Snapdragon, Dimensity and Xring devices do not run Metal, so there is no meaningful Apple-versus-Android Metal comparison.

A fair GPU comparison needs cross-platform workloads such as 3DMark or GFXBench, plus actual game testing at matched settings. Sustained frame rate, power consumption and device temperature are more useful than a single short-run score when choosing a flagship phone for gaming or video creation.

2nm cost pressure: expensive silicon, uncertain per-phone impact

Industry estimates place a TSMC 2nm wafer at around $30,000, compared with roughly $20,000 for 3nm. That implies a premium of about 50%; using a lower 3nm estimate of $18,500 produces a difference closer to 62%. Wafer prices are estimates rather than TSMC list prices, so a range is more defensible than one exact percentage. 5055

Memory costs add a separate source of pressure. A TrendForce-based report projected conventional DRAM contract prices to rise 58%–63% quarter over quarter in Q2 2026, while NAND Flash was projected to rise 70%–75%, not 55%–60%. 58

These inputs do not translate directly into a per-iPhone price increase. The eventual cost of a chip depends on die size, yield, packaging, the number of usable dies per wafer, supply agreements and volume. But the direction is clear: leading-edge logic and memory both make premium-phone component bills harder to manage.

What the iPhone 18 Pro Max AnTuTu listing adds

AnTuTu’s reported backend listing for iPhone19,3—identified as the likely iPhone 18 Pro Max by its 2,868 × 1,320 display—shows A20 Pro, 12GB of RAM, 512GB of storage and iOS 27. It recorded an overall AnTuTu iOS V11 score of 3,551,073, including 920,410 in CPU and 1,397,374 in GPU. 33

The 512GB figure describes the tested configuration, not the entry-level model. Apple’s Pro models are offered in 256GB, 512GB, 1TB and 2TB capacities. 32 The listing supports the view that A20 Pro ships in a more generously configured flagship platform, but it does not establish battery life, AI capability or long-session performance on its own.

Bottom line

A20 Pro’s early numbers make Apple the apparent leader in the reported single-core comparison and show a substantial generational graphics uplift. Xiaomi’s reported Xring O3 score remains ahead in multi-core throughput, while Snapdragon and Dimensity results are too preliminary and inconsistent for a definitive pecking order. 4192730

For buyers, the most promising A20 Pro story is not the 4,725 single-core score alone. It is the combination of high peak performance, a seven-core GPU and a new vapor-chamber approach intended to keep more performance available when workloads last longer. Independent retail-device testing will determine whether that promise holds up. 16
