Qualcomm announces its first actual laptop CPU - Snapdragon 8cx - Core i5 performance

Considering the A12X (which claims to be as fast as an i7) this honestly isn't far fetched at all.

*a first gen dual i7 which barely matches core 2 quads

 

Honestly its kind of difficult to believe that anything based on current ARM architectures is capable of matching x86 CPU when given the same power budget (or lower ones).

I sincerely doubt that it can match an i5 in anything that browsing VERY basic web pages, and even then, that's more attributed to diminished returns on the performance the i5 offers.

It probably does but seeing as applications that need that performance will be emulated on ARM anyway, there's not much point.

Against a what generation i5? Can't be Kaby Lake-U.

I have No idea but I assume an older one.

 

Edit.

 

Did some Google's Core i5-7300

I meant Kaby Lake-R (it's been a day) but yeah, I assume an older i5 as well.

See me edit they say a Core i5-7300

Bold. We'll see how it fares in real-world tests.

[DrMacintosh]

Yeah no, I'd wager that those Y series Intel chips are better in than this ARM SoC 99% of scenarios.

It is literally in its infancy. Nothing uses it and the few things that do are beta testing platforms that cost more than an x86 equivalent. Did I mention that they are all also terrible?

Except the A12 and A12X can only beat an x86 processor in the tasks that programs like Geekbench test for. The A12/X couldn’t replace an Intel Core processor if it got shoehorned into running x86. The same thing is going to happen to this Qualcomm chip no matter how fast they claim to have made it. 

 

There is an instruction set barrier and until that is removed, you'll always be getting a worse experience with Windows on ARM

Mm, not quite. Back during the Acorn days, when ARM stood for "Acorn RISC Machine", there were a number of desktops sold with ARM CPUs.

 

Granted, that was before both of our times, but still! ARM on the desktop has been done before, by the original developers of the architecture.

Because it's impossible. I like Apple and what they have been able to do with their chips, but I'm no fool. ARM simply cannot match x86 parts and whoever thinks that an A12 is as fast as an i7 are ignoring context and what these benchmarks that claim those kinds of things are actually testing for.

Space travel has been done before, but It's safe to say that space travel is still in its infancy. 

 

Just because something was done before doesn't mean that it was worth while, done well, actually changed anything, or sparked a market trend.

tbh ARM PCs back then were mostly workstations rather than regular, general purpose desktops

Ahh so yes, emulating x86 on ARM is in its infancy

That much is in its infancy, yes.

Yea there is no way this is performing anywhere near as well as an i5. No one just trumps Intel not even AMD can do that.

What it actually means is you'll be getting a smaller battery.

Yup I am surprised at the capacity of the low discharge cells of a laptop. 50Wh is not much, used to dealing in hundreds and a thousand or two Wh. A laptop battery is an old lightbulb.

 

I would say its more the a "nice" boost in battery life.

It is a drastic improvement in battery life, for those that need it. Every place now has usb outlets to plug into.

I'm already waiting for Jan. Lisa Su must feed the beast at CES. It will be interesting to see if she gives a satisfying meal. More importantly, if she does, especially on the power figures, it is likely that AMD mobile parts will crush this ARM cpu hands down.

>Core i5U Performance

By what metric?
The way Instruction Sets work in ARM is completely different from x86-64 CPUs...(RISC vs CISC)...

 

Sounds like the same type of marketing mumbling people do whenever Tablet and Smartphone performance are pit against the traditional PC.

[Settlerteo]

Oh that's news!! 
I d love to see more manufacturers join pcmasterrace. The more slices the market-share pie has, the more we will benefit as consumers in terms of performance and price.
Let's welcome Qualcomm to the race and, please ARM  you are welcome to join too here.

[Phentos]

Still an ARM CPU, meaning it may be another decade before they catch up to x86 in terms of relevance for gaming or professional/datacenter markets. 

 

And that's me being optimistic lol.
