NVIDIA GeForce GT 640 review roundup: a $99 card that fails to keep Kepler's promise
NVIDIA blew reviewers away with its flagship GTX 680, but building cards for the low-end is a whole different challenge. The GT 640 hits the $99 price point, where it sits right between the AMD Radeon HD 7750 at $109 and the last-gen Radeon 6670 at around $80. As it turns out, these rivals pull off something of a pincer movement, leaving NVIDIA's card little room to retaliate. The GT 640 contains a 28nm Kepler chip, but it's a cutdown version of the silicon with just 384 CUDA cores, a poor memory bandwidth of 28.5GB/s and no GPU Boost feature -- which means the card can't boost its 900MHz to make use of thermal headroom. These limitations have a significant impact on the benchmarks, as you'll see in our little review roundup after the break.
NVIDIA GeForce GTX 670 review round-up: 'just get here if you can'
While the world still waits for the GTX 680 to reach Newegg, NVIDIA has pushed ahead with the next card down in its stack: the $399 GTX 670. This more affordable option keeps most of the main Kepler credentials intact, but it necessarily makes a few compromises on the computational side, with fewer processing cores (1344 instead of 1536) and texture units (112 instead of 128) as well as slower base clock speed (915MHz instead of 1006MHz). Is that likely to be a problem? Judging from reviewers' responses published today, which cover cards from a range of vendors, probably not. In fact, as TechSpot puts it, "there's very little to critique," because the GTX 670 matches the performance of AMD's flagship Radeon HD 7970 at a much lower price. AnandTech's benchmarks put the reference board only ten percent (or a handful of fps) behind the GTX 680 in many recent games, leaving it "nipping at the 7970's heels," but it was still plenty powerful enough to play Arkham City or Battlefield 3 at 5760 x 1200 with high settings. PCPer's stats put the new card 15 to 20 percent behind the 680, but found good scaling in SLI mode. The Tech Report found the the GTX 670's cheap stock cooler let it down slightly, with a "friction-filled" idle noise well above the top-end Radeons and even above the dual-GPU GTX 690 -- but under load it conducted itself relatively well. We could go on, but ultimately if you're looking to buy this card then you'll want to do your own research at the links below, and then do a raindance.

An early look at Ivy Bridge motherboards: or, the side order without the main
Ssshh. Ivy Bridge is officially still a mystery, remember? Nevertheless, through some quirk of chronology, the accompanying Z77 chipset for motherboards has already been announced. If there's a reason for this early entrance, it's probably because Z77 is backwards compatible with Sandy Bridge, which means that the latest crop of motherboards from Asus, Gigabyte, Intel and MSI can be considered fully-fledged products in their own right. Well, kind of, anyway. In reality, some of the key selling points of Z77 won't get activated until you clamp on Ivy Bridge silicon -- including PCIe 3.0 support (hitherto only found on X79 big-momma-boards), so the real testing can't begin in earnest until the new kid arrives. With that caveat out of the way, read on for a quick review round-up.
NVIDIA GeForce GTX 680 review round-up: see ya later, AMD
We've already been hands-on with NVIDIA's first Kepler GPU, but all those fancy features count for nuthin' if the benchmarks don't back them up. So do they? Huh? Do they? NVIDIA told us to expect a 10 to 40 percent performance boost from the $499 GTX 680, versus AMD's pricier Radeon HD 7970, and it appears that was no exaggeration. If you've bought yourself a high-end 28nm AMD card recently, try to hold back those tears until you've glanced over the reviews after the break. Let's just hope for a fairer fight when NVIDIA's mainstream and low-end cards come out to tackle AMD's 7800- and 7700-series -- and hey, some timely price drops could help to balance things too.
AMD's 'sweet spot' Radeon HD 7870 and 7850 graphics cards get reviewed, recommended
AMD's Radeon HD 7000-series onslaught continues, with still no 28nm retort from NVIDIA. The latest offerings are the 7870 priced at $349, and the 7850 priced at $249. Both are based on the Pitcairn GPU and hog the mainstream gamer spot below the Tahiti-based 79xx cards and far above the 77xx options. In terms of competition, these cards go head-to-head with the older NVIDIA GeForce GTX 570 and GTX 560Ti, which currently retail for between $20 and $50 less. However, most reviewers found plenty of reasons to side with AMD despite the extra outlay, as you'll discover at the links below.HotHardware -- hailed the performance, low power consumption, noise levels and features of both cards, but noted that they're "not much faster than previous gen counterparts." For example, 3DMark 11 benchmarks generally beat NVIDIA's rivals by around two or three percent, while the Radeon HD 7850 barely scored any higher than its predecessor, the 6850, in that test.AnandTech -- found the 7870 to be "faster, cooler and quieter" than the GTX 570, with a roughly nine percent performance advantage that puts AMD "in the clear for the time being." As for the 7850, it was regarded as less of a steal, trailing the cheaper GTX 560Ti in some games -- including an eight percent lag in Battlefield 3.TheTechReport -- reckoned both the 7870 and 7850 are "better options than comparable GeForces," because they deliver more FPS-per-dollar when Arkham City, Battlefield 3, Crysis 2 and Skyrim performances are averaged out.PC Perspective -- concluded that the Radeon HD 7870 "more or less matches" the GTX 570 in the six games it compared, with two wins, two losses and two draws for the AMD card, but is still "pretty impressive" for the price. The HD 7850, meanwhile, "completely dominates the performance metrics" while using "56 fewer watts!"TechSpot -- gave the Radeon HD 7850 slightly higher marks for being the "best mainstream card to buy at $250," while also praising the HD 7870 delivering "excellent performance and overclocking" and "almost reaching the level of the more expensive HD 7900 boards."
AMD Llano desktop APU gets reviewed: the best integrated graphics in town
AMD is due to release a batch of new Llano APUs next month that are specifically tailored to desktops rather than laptops. The most powerful among them will be the 2.9GHz A8-3850, which has already caused a stir on the review circuit for one simple reason: it pulls off a brutal "one shot one kill" on Intel's HD 3000 integrated graphics. AnandTech raised an impressed eyebrow at the fact that all its benchmarking games were playable on the $135 AMD chip, which roughly doubled frame rates in titles like Modern Warfare 2, Bioshock 2 and World of Warcraft compared to the more expensive Sandy Bridge i5 2500K. TechSpot declared the APU its "new budget king," with graphical performance "on another level" compared even to an i7. However, the superlatives quickly evaporated once reviewers shifted their focus to the CPU. TechReport spotted that pure CPU performance per dollar was actually lower than what you'd get from a lowly i3. Moreover, it reckoned you'd only have to spend an extra $70 to buy a much more powerful CPU and a separate graphics card -- an option that comes "awfully close to making the A8-3850 seem irrelevant." Ouch. Nevertheless, if an affordable processor with integrated graphics is what you're after, then it's fair to say this one sets the standard. Click the source links below for full reviews.
AMD elevates the low-end with trio of sub-$100 cards: Radeon HD 6670, 6570, and 6450
Graphics card companies don't live and die by the enthusiast market alone. That may be where the glory is, but it's the budget cards that really bring in the bacon. For the entry level, AMD just unleashed a trio of sub-$100 cards, the Radeon HD 6670, 6570, and 6450. How do they perform? Well, let's just say you get what you pay for. Reaction from reviewers has been one of mild indifference. Depending on manufacturer, fan noise does appear to be an issue, possibly precluding the cards from being a viable HTPC choice. Otherwise, even the lowly, $55 6450 is a worthy upgrade over an integrated graphics chip or a two-year-old discrete card, but it can't match the performance of NVIDIA's GT 430, which can be had for only a few dollars more. Consensus was that, with prices of the older 5000 series being slashed, purchasers can get more bang for their GPU buck by sticking with last generation cards (like the Radeon HD 5750) if they're looking for pure gaming prowess. That said, the GDDR5 flavors of the 6670 provide perfectly playable performance on most modern games (it averaged 45 FPS in Call of Duty: Black Ops) for just $99 (the 6570 runs about $79). Just beware those models shipping with GDDR3. Benchmarks galore below.

Nikon D3 review round-up: survey says you'll want one
We've already seen it previewed and unboxed, but now that Nikon's super high-end D3 DSLR has been out for a little while, we're starting to get some full-on reviews of the camera and, as you might have guessed if you've been lucky enough to get your hands on one, there's plenty of consensus going on. Indeed, the praise being heaped on the camera is among the loftiest we've seen, with Photography Blog calling it "pretty much peerless," Think Camera declaring that "the files coming out of the Nikon D3 look better than any camera we've seen to date," and Ken Rockwell flat out calling it "the best camera ever made by Nikon." Needless to say, the upsides to the camera are a little long to list here, but it particularly fares well when it comes to rapid-fire image capture and low light photography, which makes it especially well-suited to press photographers. The biggest single complaint the reviewers could find was a lack of any built-in sensor cleaning technology, with only a couple of minor design flaws (like a lack of a spring inside the CF card door) attracting their attention otherwise. There's also, of course, that nearly $5,000 price tag, but we're guessing anyone actually in the market for the camera make do with that in turn for the results they'll get.Read - Photography Blog (5 out of 5)Read - Think Camera (9 out of 10)Read - KenRockwell.com ("the best camera ever made by Nikon")
