Re: [id-android] WTI Samsung Menipu Nilai Benchmark S4

Silahkan diintip, om Amer

Ada link ke AnandTech nya beserta screen capture

Jadi ketika pakai Benchmark tertentu, kecepatan cpu dan gpu naik, min 10%. Bahkan ada yang berlipat lebih 2x
Ketika untuk kerja biasa, kembali turun

Sayangnya, atau sialnya, ada 1 benchmark yang tidak tercantum di script agar naik kecepatan
Hehehehehhe

Naiknya menggunakan script tertentu

Jadi ngga ada kaitannya dengan sgs4 yang octacore atau bukan octacore

Maksudnya clock nya om. Waktu diumumkan pake yg setelah oc atau sebelum.

Om Amer
Cpu yang digunakan adalah sudah yang Octacore
Yang menemukan pertama kali adalah AnandTech

Masalahnya saat score itu diumumkan digunakan cpu yg berapa? Yg sudah di oc atau yg bukan? Itu akan jadi pembedaan antara mengakali dengan menipu.

Kayaknya judulnya harusnya mengakali, bukan menipu. Kan kenyataannya governornya bisa diset ke mode performance.

Samsung Rigged the S4 to Unnaturally Perform Better in Benchmark Tests

The Samsung Galaxy S4 is a damn fine phone. It's fast, it's big, it's thin and it's completely deserving to be in most people's pockets. But apparently that's not enough for Samsung. Samsung has gotten caught cheating benchmark tests to make itself look better. Basically, the S4 is specifically tweaked to be better at benchmarking than anything else it does.

Anandtech found that the S4 games its GPU to spit out a 533MHz clock speed in certain benchmark tests (AnTuTu, GLBenchmark 2.5.1 and Quadrant) while most every other app and game performance is limited to 480MHz (some other benchmark apps show a lower clock speed too). 533MHz obviously sounds a lot more impressive than 480MHz.

It's gets funnier. Even the S4's CPU spits out lies in certain benchmark tests. In GLBenchmark 2.5.1, the CPU clocks in at 1.2GHz and never dips below it. In GFXBench 2.7, the CPU can go to 500MHz (250MHz virtual frequency). Basically, when the S4 is in GLBenchmark 2.5.1 (and other benchmark tests), it's allowed to run in a higher performance benchmark mode, an unnatural boost to make its numbers look better in fake situations while hiding its actual real life performance.

But could it be different benchmark tests giving different results? No. Anandtech found a stringthat shows the S4 is hardcoded to specficailly perform better in certain apps for benchmark testing, with "Quadrant standard, advanced, and professional, linpack (free, not paid), Benchmark Pi, and AnTuTu" being mentioned:
