Arm a72?

Sorry, was thinking about 32-bit code. Yes, standard v8 does require Neon. If it is vectorized, it's very poorly done. A7 with the Accelerate library can push over 8 GFlops/s DGEMM per core, while geekbench reports less than 2. Obviously these libraries aren't available for Android, but the...

Arm a72?

I think it's actually running at 2.0 GHz, not the 1.57 GHz listed. The MediaTek part has 2 A72 cores @ 2.0 GHz and 2 A53 @ 1.6 GHz. I really doubt these results are on the A53 cores.

Arm a72?

Oh nice! Didn't realize there were benchmarks out yet. I don't think any of the geekbench benchmarks are vectorized, as they have to run on all hardware (no-neon, etc). If that were the case the A7 FP numbers would be much higher.

Arm a72?

I'm guessing Apple A7 will still be faster than A72. Single core performance, I mean.

When is the best time to buy a new Intel cpu? (tick vs tock vs refresh/new vs used)

Only 10-20 tabs? This seems pretty high, I usually have like 5-8 tabs though it sometimes peaks to 30+ tabs across multiple windows. Obviously it depends on what's running in those tabs, but I'm using 2600K with HT off on Linux and my cpu utilization is around 2% across all cores. I have a...

AMD Carrizo Pre-release thread

Excavator supports 256-bit AVX2 instructions, but it needs to split them up into 2 micro instructions. So any 256-bit AVX2 instruction will look worse or be a wash compared to 128-bit AVX/SSE.

If all you do is game, then there is absolutely no reason to upgrade. Only thing I can think of is if you want 8 threads, go for i7.

Apple A9X the new mobile SoC king

Do you have a link to the source? Or did you just disassemble the app?

Apple A9X the new mobile SoC king

Yes, I totally agree. The common code argument only goes so far. For well known benchmarks (dhrystone, Spec CPU) compilers will optimize out a lot of the code. Take for example, libquantum in CPU2006.

Apple A9X the new mobile SoC king

If it used the Accelerate library you'd see quite a large increase in many of the tests, especially in the GEMMs.

With Intel's 99% share of x86 server market, they are doing pretty well with margins these days.

iPhone 6S' performance is monstrous

A8 had 1M L2, just like A7. In terms of CPU performance, Apple is at least a year ahead of any ARM part. If they can scale frequency up, they could take on Intel. Of course there is the issue with x86 dominance, but Apple has gone through architecture changes before and quite seamlessly for the...

Apple A9X the new mobile SoC king

Correction, my statement are +20% over A8 at same frequency. At 1.8 GHz, most of the tests are showing +50-60% improvement over 1.4 GHz A8.

It only skews it by ~200/300 points. A lot of the tests went up by 20+%.

Disable CPU Core #2 Through BIOS Settings

Awesome, great to hear that it solved your issues! I suppose you can create a startup service to automatically set this up for you. But as long as you don't shutdown, you should be fine. I'm not sure what would happen on standby/sleep, hopefully it sticks.

Disable CPU Core #2 Through BIOS Settings

Okay, if you can boot into Linux and have sudo access, try this: First read to see original value: sudo lspci -s 00:18.3 -xxxx | grep 190 Should see something like this: 190: 00 00 00 00 00 00 00 00 00 00 00 04 00 00 00 00 Now set bit 2 of F3x190: (assuming cores ordered 0, 1, 2, 3...

Disable CPU Core #2 Through BIOS Settings

What I mean is not OS downcoring, but system downcoring. If you set bit 2 for register F3x190, then core 2 will be disabled on reboot. If you can boot to anything and have access to PCI space this is the easiest thing to do. The BIOS downcoring options would typically disable the cores in reverse.

Does anyone know how Anandtech is running CPU2000 on iPhone? Did they create an app, or using a jailbroken device via command line? CPU2006 version of mcf will be difficult to run with only 2GB RAM. The way these phone/tablet OS's segment off memory (without swap) the devices tend to crash and...

iPhone 4 as second computer screen?

You can jailbreak it, install synergy and use it somewhat as a second screen. Use your desktop mouse and keyboard to control the apps on your phone!
