Apple M1 対 Intel i7:ベンチマークの戦い

初めてではありませんが、Apple は自社のコンピューターが使用する基本的なテクノロジーを完全に変更しました。 1995 年に会社が Motorola CPU から IBM PowerPC に移行したときにそれが起こりました。そして 2006 年に Intel に移行したときに再び起こりました。現在、Apple の ARM ベースの M1 チップを使用する 3 つの新しい Mac があります。

これは、Intel Core i7 などと比較されている iPad 由来の CPU です。 Apple M1 対 Intel Core i7 という考えは理にかなっていますか?パフォーマンス重視の新しい Mac をお探しの場合は、このまま読み進めてください。すべてを詳しく説明します。

M1 の何が特別なの?

M1チップは「Appleシリコン」と呼ばれています。つまり、Apple が社内で設計したカスタム マイクロプロセッサです。これは、大部分の携帯電話やタブレットが使用する ARM 命令セットを使用します。これは、世界中のほとんどのデスクトップおよびラップトップ コンピューターで使用されている Intel x86 命令セットとは対照的です。

Apple の ARM チップはいくつかの理由で特別です。まず、ほとんどのモバイル ARM CPU に比べてサイズが大きく複雑です。また、CPU、キャッシュ、RAM、GPU を含むシステム全体を緊密に統合します。

これらのチップは、Apple の iOS および ARM ベースの macOS ソフトウェアを可能な限り効率的に実行するようにも設計されています。このゼロから開発された社内設計は、驚異的なパフォーマンスを約束します。少なくとも理想的な状況では。問題は、Apple M1 は、一般的なプロ仕様の高性能チップと比べてどれくらい速いかということです。 Intel Core i7 のような CPU?

はい、M1 は Intel i7 (および i9!) を上回っています

M1 MacBook Air、Macbook Pro、および Mac Mini は、執筆時点では予約注文のみ可能です。ただし、メディアの一部のメンバーは、所有しているユニットを持っています。また、M1 と Core i7-1165G7 などのチップを比較するベンチマークがリークされています。

ベンチマークには、Cinebench R23 と Geekbench が含まれます。これらは、さまざまな CPU アーキテクチャと命令セットでパフォーマンスをテストできるプログラムです。このベンチマークの異なるバージョンは CPU に同じワークロードを提示するため、CPU が実際に作業を行う能力を表しています。

Techradar の記事によると、リークされた結果は、MacBook Pro 13 の M1 が Cinebench R23 のシングルコア テストで 1498 ポイントを獲得したことを示しています。 Core i7-1165G7 は 1382 ポイントを獲得しました。 The M1 is also slightly ahead in the multi-core test.

Even more impressive, Apple Insider reports that the M1 is outperforming the Core i9 in the recent MacBook Pro 16. At least when it comes to Geekbench scores. However, keep in mind that a Macbook Pro 16 costs thousands of dollars!

The bottom line is that anyone concerned about raw performance when it comes to these new Macs doesn’t have anything to worry about. They are a clear step above (or at least equal to) anything Apple has ever released.

The M1 Is About More Than Performance

Performance is only a part of the equation when it comes to the M1. Apple computers such as the Macbooks have been struggling with high power consumption and hot CPU temperatures for years now. Intel has failed to deliver cooler, more power-efficient chips. This leads to performance throttling.

The M1 addresses both of these issues. ARM processors are designed to do more work with less power. Which translates to longer battery life and less heat. The M1 is so good at this that Apple has not put any fans on the M1 Macbook Air at all. This means its name is now just a little ironic.

With a much longer battery life, the mobile usability of these new Macbooks is increased by a large margin. That means you make no sacrifices in raw performance and get longer battery life. Seems like a pretty good deal, right?

It’s also worth noting that the M1 Macbook Air, despite having the same chip as the Pro, won’t perform to the same level. That’s thanks to the passive cooling solution Apple is using. This restricts how hard the M1 can push itself. So don’t expect the M1 in the Air to be as fast as an air-cooled i7 processor running a sustained load!

M1 vs Intel i7:It’s Complicated

Here is where the good news becomes a little less rosy. The M1 is a fast and power-efficient chip. However, Apple has to run computer code designed for Intel chips through a complex translation system called Rosetta 2.

While this allows M1 Macs to run any software designed for Intel Macs, it comes with a performance penalty. For some programs, the reduced performance doesn’t make a difference in any practical sense. For others, it might be a problem. The issue is that there’s no way to know how well or poorly x86 software will perform on an ARM Mac until someone tests it.

Software Support Matters

That brings us to software support for M1 Apple computers. Apple itself provides native, full-performance versions of all its software for the M1. As you can imagine, creative and productivity applications that current Mac users rely on are also being ported to work natively on the M1. How quickly your mission-critical macOS apps will be translated to M1-compatible code depends on each developer.

It also depends on the complexity of the program in question. Some companies have a head start. For example, Adobe has already ported the core code for PhotoShop to ARM for iOS.

Speaking of which, iOS apps will run natively on M1-equipped Macs. Giving you access to the iPad and iPhone software libraries. That’s another bonus to consider when weighing an M1 Mac as a total package.

In the end, a computer that runs the software you need poorly isn’t very useful. No matter how good it looks on paper.

Should You Buy an M1 Computer?

The big question is whether you should jump in and order an M1 Mac to replace your current unit. In the case of the Mac Mini, we would say the answer is generally “no” right now. The M1 Mac Mini can’t be upgraded, has a slower network connection than the old model, and is less attractive as an overall package.

With the M1 Macbooks, things get more interesting. Both the M1 Macbook Air and M1 Macbook Pro 13 laptops are physically almost identical to the Intel-based models. They will run all of the same software as the Intel models, as well as iOS apps and (obviously) M1-native applications. Their battery life has improved massively and their performance with native code is significantly higher than the same Intel-version apps running on Intel Macbook models.

They do take a variable performance hit when running through Rosetta 2, but in many cases, this makes them no slower than the Intel Macbooks running those same apps natively.

Overall, it seems that most users would appreciate the quality of life and performance improvements of the M1 Macbooks. However, there are certain situations in which you should think twice:

• Specific applications you need run poorly via Rosetta.
• You wish to use Boot Camp to run Windows on your Mac.

Other than that, it’s a fairly safe move as far as we can tell. Apple Silicon is the future of Mac. The only other caveat is that these first-generation M1 Macs are likely to be replaced with better implementations of the technology soon. So if you aren’t due for an upgrade, your current Macs will be just fine in the meantime.
