Re: Technology purchasing and "moments of weakness"

I currently suffer from the exact opposite problem: I go to a store with the intent of spending some money on something I want. I generally walk out empty handed. I've either gotten way too particular with my tastes or just become dull and depressed. Though in the past I did catch a sale on a Xeon P...

Re: How Apple Dethroned Intel As the World's Most Innovative Chipmaker

The video is bad but the idea that ARM gets to conserve energy by having a simpler instruction decoder. Having aligned instructions of (generally) the same length make fetch and decode pretty simple. Given the complexity of modern high performance execution units, the hit from the instruction decod...

Re: How Apple Dethroned Intel As the World's Most Innovative Chipmaker

The way I understand it ARM processors are decent for performing one task at a time, and to do a different task they need to be switched to do a different task in software. Not a good way to multitask. For raw horsepower, I don't think ARM will be able to beat the x86 design, based on, well, the wa...

Re: How Apple Dethroned Intel As the World's Most Innovative Chipmaker

Sometimes Motley Fool is insightful, but this is not one of those times. Setting aside the conspicuous lack of any actual sources, I question the author's understanding of how the ARM ecosystem actually works. But I guess it's good flamebait or whatever. Anyway, here are my predictions: -Apple will...

Gsync (rocking a 1080 so that's where I am, but I'd also be totally fine with HDMI 2.1(and thus, HDMI VRR) so long as Nvidia supports it on the 11 series as I'm likely to stick with the green team if I do get a new card) I would be surprised if any GPU supports HDMI 2.1 this year.

Re: Intel Processor bug incoming?

Well it looks like Spectre can break into SMM. This follows on the heels of another SMM attack in recent memory, coincidentally introduced in the first chips that Spectre could also be used.

Oh, and there is Spectre NG on the way too.

I believe a good chunk of the sales are clearancing out last year's model as the units announced at CES are finally shipping. Case in point, I picked up four LG 27" 4K IPS displays for $250 USD a piece and they're good units thus far. With pricing like that, the older 1920 x 1080 and 2560 x 144...

Re: The CPU-Z Benchmark Gallery

Hrm, are the 32 bit binaries using SSE at all? That could explain the big performance jump with the 64 bit version. AVX is only available in 64 bit mode but the numbers aren't aligning perfectly for that to be an explanation.

Re: Samsung FreeSync TVs in 2018

Why would Nvidia care? They don't make monitors. IIRC, GSync modules are still FPGAs and they haven't moved to ASICs yet. Nvidia probably cut all R&D of GSync modules a long time ago and are just milking the exclusivity to recoup R&D costs and get as much profit as possible until GSync sale...
