ATI CrossFireX versus NVIDIA SLI: performance scaling showdown
We know who the daddy is when it comes to single-card graphics performance, and we've even witnessed NVIDIA and ATI duking it out with multiple cards before, but this here roundup is what you might call comprehensive. Comparing a mind-boggling 23 different configurations, the Tech Report guys set out to determine the best bang for your DirectX 11 buck. Their conclusion won't shock those of you who've been following the recent love affair between reviewers and NVIDIA's GeForce GTX 460: a pair of these eminently affordable cards regularly outpaced the best single-GPU solutions out there. Slightly more intriguing, however, was the discovery that its elder siblings, the GTX 470 and 480, have improved in performance to the point of being markedly ahead of ATI's Radeon HD 5870, with the blame for this shift being put squarely on the shoulders of NVIDIA's driver update team. Hurry up and give the source a read while it's still fresh, we can't imagine ATI letting this be the status quo for too much longer.
12-core Apple Mac Pro orders are go
After a brief outage the Apple Store is back with the previously announced 12-core Mac Pro (and revamped quad- and 6-core models) ready to order. Prices start at $4,999 for a pair of 6-core Xeon Westmere processors humming along at 2.66GHz, 6GB of memory, a 1TB hard drive, SuperDrive, and ATI Radeon HD 5770 graphics. We configured ours with a pair of 2.93GHz CPUs, 2x HD 5770 graphics cards, 32GB of memory, 4x 512GB SSDs, and pair of optical drives for $16,249 just 'cause we could. Ships in 7 to 10 business days... bankruptcy in 365. [Thanks, Nathan]
Apple Mac Pro line overhauled with 12 processing cores, arriving in August for $4,999
So shall it be written, so shall it be done. The Mac Pro has at long last proven rumors of its impending refresh accurate, as Apple has just updated its most powerful hardware with even more grunt. As we'd heard previously, that means you can now get dual-CPU rigs that offer a full dozen cores to play with, courtesy of Intel's Xeon server-class chips, though in order to get in on that game you'll have to splash a cool $4,999 entry fee. The quad-core starting price is still $2,499, though the eight-core machines have jumped up to $3,499, with both variants getting mild speed bumps to 2.8GHz and 2.4GHz, respectively. Perhaps the most welcome upgrade is on the graphical front, where the Radeon HD 5770 takes up the mantle of default GPU, with additional options for a pair of such cards or a step up to a 1GB HD 5870 alternative if you're keen on maxing out those frame rates. Memory isn't neglected either, with choices ranging all the way up to 32GB of RAM, 4TB of conventional HDD storage, or an array of four 512GB SSDs -- though you're probably better off not asking how much that last one will set you back. The comprehensive specs can be found in the full press release after the break.%Gallery-98277%
ATI Radeon HD 5770 and 5750 steal away reviewers' hearts
The ATI onslaught of 40nm DirectX 11 parts continues today with two even cheaper variants coming from its Evergreen family of chips. Based on the Juniper core, the HD 5770 and 5750 represent ATI's mainstream value proposition, with compute performance of more than 1 TFLOPS and pricing between $109 and $159. There's a significant dropoff in specs from the world-conquering HD 5870 and similarly potent HD 5850, but reviewers found the latest cards were still up to the task, with the 5770's performance said to be "just shy" of the very recent top dog for ATI, the HD 4890. With low power consumption, competitive pricing and added features like Eyefinity and 7.1 HD audio, the new cards might not push performance boundaries, but they also leave you with little reason to look elsewhere for your next GPU purchase.
