AnandTech benchmarked the new RTX graphics cards, and concludes:
So where does that leave things? For traditional performance, both RTX cards line up with current NVIDIA offerings, giving a straightforward point-of-reference for gamers. The observed performance delta between the RTX 2080 Founders Edition and GTX 1080 Ti Founders Edition is at a level achievable by the Titan Xp or overclocked custom GTX 1080 Ti’s. Meanwhile, NVIDIA mentioned that the RTX 2080 Ti should be equal to or faster than the Titan V, and while we currently do not have the card on hand to confirm this, the performance difference from when we did review that card is in-line with NVIDIA's statements.
The easier takeaway is that these cards would not be a good buy for GTX 1080 Ti owners, as the RTX 2080 would be a sidegrade and the RTX 2080 Ti would be offering 37% more performance for $1200, a performance difference akin upgrading to a GTX 1080 Ti from a GTX 1080. For prospective buyers in general, it largely depends on how long the GTX 1080 Ti will be on shelves, because as it stands, the RTX 2080 is around $90 more expensive and less likely to be in stock. Looking to the RTX 2080 Ti, diminishing returns start to kick in, where paying 43% or 50% more gets you 27-28% more performance.
Neither of the two new RTX cards seem to be particularly smart purchases at this point - the 2080 barely performs any better than a 1080 Ti, and while the 2080 Ti does offer a decent performance improvement over the 1080 Ti, it's also $1200. You might want to wait to see if NVIDIA's raytracing efforts pay off and gets adopted in video games, and if said raytracing features don't suck too much performance.
Does anyone remember our articles regarding unscrupulous benchmark behavior back in 2013? At the time we called the industry out on the fact that most vendors were increasing thermal and power limits to boost their scores in common benchmark software. Fast forward to 2018, and it is happening again.
Companies lie. They lie all the time. As with anything related to performance measuring and comparisons - wait for trusted third party benchmarks from places like AnandTech and GamersNexus. Company-provided figures are almost always anything from unrealistic best-case scenarios at best, or downright lies at worst.
It's well-known that you should measure the performance of your code, and not rely only on the opcode's "cycle counts".
But how fast is an IBM PC 5150 compared to a PCjr? Or to a Tandy 1000? Or how fast is the Tandy 1000 HX in fast mode (7.16Mhz) compared to the slow mode (4.77Mhz)? Or how fast is a nop compared to a cwd?
I created a test (perf.asm) that measures the performance of different opcodes and run it on different Intel 8088 machines. I run the test multiple times just to make sure the results were stable enough. All interrupts were disabled, except the Timer (of course). And on the PCjr the NMI is disabled as well.
There's no point in any of these benchmarks, but that doesn't make them any less interesting.
The "Bionic" part in the name of Apple's A11 Bionic chip isn't just marketing speak. It's the most powerful processor ever put in a mobile phone. We've put this chip to the test in both synthetic benchmarks and some real-world speed trials, and it obliterates every Android phone we tested.
As far as SoCs go, Apple is incredibly far ahead of Qualcomm and Samsung. These companies have some serious soul-searching to do.
I can't wait for AnandTech to dive into the A11 Bionic, so we can get some more details than just people comparing GeekBench scores.
Intel's latest 10-core, high-end desktop (HEDT) chip - the Core i9-7900X - costs Â£900/$1000. That's Â£500/$500 less than its predecessor, the i7-6950X. In previous years, such cost-cutting would have been regarded as generous. You might, at a stretch, even call it good value. But that was at a time when Intel's monopoly on the CPU market was as its strongest, before a resurgent AMD lay waste to the idea that a chip with more than four cores be reserved for those with the fattest wallets.
AMD's Ryzen is far from perfect. But when you can buy eight cores that serve even the heaviest of multitaskers and content creators for well under half the price of an Intel HEDT chip, i9 and X299 are a hard sell (except, perhaps, to fussy gamers that demand a no-compromises system).
The question is: Are you willing to pay a premium for the best performing silicon on the market? Or is Ryzen, gaming foibles and all, good enough?
I've said this countless times, but I want to keep bringing this one home: this is what competition does. It lowers prices, improves performance, and makes Intel looks like a stumbling fool. And what better day to celebrate the benefits of competition than today?
Cheers, America. Party safe!
So there you have it. As of October 4, Google Now has a clear lead in terms of the sheer volume of queries addressed, and more complete accuracy with its queries than either Siri or Cortana. All three parties will keep investing in this type of technology, but the cold hard facts are that Google is progressing the fastest on all fronts.
Not surprising, really, considering Google's huge information lead. Still, I have yet to find much use for these personal assistants - I essentially only use Google Now to set alarms and do simple Google queries, but even then only the English ones that do not contain complicated names.
With the exception of Apple and Motorola, literally every single OEM we've worked with ships (or has shipped) at least one device that runs this silly CPU optimization. It's possible that older Motorola devices might've done the same thing, but none of the newer devices we have on hand exhibited the behavior. It's a systemic problem that seems to have surfaced over the last two years, and one that extends far beyond Samsung.
Pathetic, but this has been going on in the wider industry for as long as I can remember - graphics chip makers come to mind, for instance. Still, this is clearly scumbag behaviour designed to mislead consumers.
On the other hand, if you buy a phone based on silly artificial benchmark scores, you deserve to be cheated.
