I was really under the gun when I was trying to finish up my GeForce GTX 970 and 980 review. As a result, I wasn't able to track down the cause of an interesting anomaly in my test results. Have a look at the theoretical peak pixel fill rate of the GTX 970 and 980 reference cards (along with the Asus Strix 970 card we tested) based on the GPU's active ROP count and clock speed:

  Peak pixel

One of the more intriguing capabilities Nvidia introduced with the GeForce GTX 970 and 980 is a feature called Dynamic Super Resolution, or DSR, for short. DSR is a way for a fast GPU to offer improved image quality on a lower-resolution display. Nvidia bills it as a means of getting 4K quality on a 2K display.

That sounds a little too good to be true, but still, my interest is piqued. Given that a whopping 77% of TR readers have monitors with a resolution of 1920x1200 or lower, I suspect DSR might ...

Typical PC enthusiasts may spend more on their PCs than you might think—and by the looks of it, their taste for high-end hardware isn't just limited to core components.

Those are two of the main takeaways from the TR Hardware Survey 2014, in which we invited readers to answer 26 questions about their PCs. Around ...

Flash memory is simultaneously shrinking and expanding. The actual memory cells are getting smaller thanks to advancements in fabrication technology, fueling an increase in density that enables higher-capacity chips. For the most part, that's just great. Higher bit densities reduce the cost per gigabyte, while higher-capacity chips facilitate SSDs with more total storage.

Unfortunately, stuffing more gigabytes into each chip also presents a problem. SSDs now require fewer chips to hit the same capacity, and in some cases, they ...

You won't believe how much data can be written to modern SSDs. No, seriously. Our ongoing SSD Endurance Experiment has demonstrated that some consumer-grade drives can withstand over a petabyte of writes before burning out. That's a hyperbole-worthy total for a class of products typically rated to survive only a few hundred terabytes at most.

Our experiment began with the Corsair Neutron GTX 240GB, Intel 335 Series 240GB, Samsung 840 Series 250GB, and Samsung 840 Pro 256GB, plus two Kingston HyperX 3K 240GB drives. They all surpassed their endurance specifications, but the ...

2014 has been a strange year for graphics chips. Many of the GeForce and Radeon graphics cards currently on the market are based on GPUs over two years old. Rather than freshening up their entire silicon lineups top-to-bottom like in the past, AMD and Nvidia have chosen to take smaller, incremental steps forward.

Both firms introduced larger chips based on existing GPU architectures last year. Then, two weeks ago, the Tonga GPU in the Radeon R9 285 surprised us with formidable new technology that's still somewhat mysterious. Before that, this past spring, Nvidia unveiled its ...

A staggering assortment of Serial ATA SSDs has passed through the Benchmarking Sweatshop in recent years. Seriously, we've got results for something like 70 drives on our current testbed alone. Most of them use eight-channel controllers either developed in-house by the drive makers or selected from Marvell or SandForce stocks. Each new generation brings lower prices thanks to NAND built on a finer fabrication process, but they all start to look the same after a while.

Then, every so often, one of them stands out. The Adata Premier SP610 isn't yet another die-shrunk spin on a familiar controller; it's based on an entirely unfamiliar Silicon Motion SM2246EN chip that gets by on ...

One of the funny things about Intel's workstation- and server-class Xeon processors is that we kind of think we know what's coming before each new generation arrives. For instance, the new generation of chips known as Haswell-EP is making its debut today, yet the Haswell microarchitecture has been shipping in client systems for over a year. The desktop derivative of this very silicon, Haswell-E, was introduced late last month, too.

What amazes me about the new Xeons, though, is how much more there is to them than one might have expected. Intel's architects and designers have crammed formidable new technologies into these chips in order to allow them to scale up to large ...

In many ways, AMD's FX processor series seems to have fallen by the wayside lately. While A-series APUs were refreshed with new Kaveri silicon this past January, the FX family has been trucking along with the same Vishera silicon since 2012. The accompanying 990FX chipset is a year older and begging for a replacement. At this point, one might have expected AMD to let the FX family die a dignified death—then fill in the gaps with high-octane Kaveri APUs.

But that's not ...

As a guy who reviews video cards, it's pretty easy to become cynical about these things. That's been especially true during the past couple of years, as we've seen the same handful of graphics chips spun into multiple "generations" of products. The core GPU technology is a technological wonder, but the endless re-spins get to be tiresome.

When AMD revealed the imminent arrival of the Radeon R9 285 recently, I have to admit, I wasn't exactly thrilled. Yes, the R9 285 would be ...

I recently reviewed Cooler Master's Elite 110 Mini-ITX case, and while I found it suitable for a mid-range gaming PC, I felt that it might leave the enthusiast builder wanting. Today, I'm taking a look at Corsair's latest enthusiast-oriented Mini-ITX enclosure, the Graphite Series 380T. With a built-in fan controller, enough room for high-end components and their accompanying coolers, and aggressive styling, the 380T seems set to play the Ferrari or Lamborghini to the subdued, subcompact Elite 110. Is there substance under all of that style? I'm going to fill 'er up with some high-performance components and find out.

At long last, Haswell-E is upon us—and it was worth the wait. Intel's latest high-end desktop processor crams up to eight cores and 16 threads into a single socket. It has enough PCIe Gen3 lanes to fuel exotic graphics configurations, and it's backed by quad channels of DDR4 memory. So, yeah, pretty awesome.

And the processor is just one part of the overall package. Haswell-E comes with a new chipset, dubbed X99, that replaces the aging X79 Express Intel has been milking since the Sandy Bridge era. This updated I/O hub brings ...

For a PC hobbyist who's into building high-end systems with elaborate water-cooling setups and multiple GPUs, it doesn't get any better than Intel's Core i7 Extreme processors. They're pricey, sure, but they're clearly the fastest, most capable CPUs on the planet.
