Much like a previous exposé with Radeon HD 7950, the specifications of Radeon HD 7770 that were rumored in our previous article have been confirmed by users. It confirms several specifications, starting from the stream processor count of 640, to the 128-bit wide GDDR5 memory interface. The GPU has an out of the box core clock speed of 1.00 GHz, it could be possible that this is a factory-overclocked card, if not, the core clock speed rumor sparked off by the Verdetrol marketing campaign are true, after all.

TechPowerUp today released the latest version of GPU-Z, the popular graphics subsystem information and diagnostic utility. GPU-Z briefs you on the graphics hardware installed in the system, and lets you monitor clock speeds, voltages, temperatures, fan-speeds, and other information in real-time. The new version adds full-support for AMD's Radeon HD 7700 series "Cape Verde" GPUs (HD 7770 and HD 7750) that are bound for launch a little later this month. The new version also has an updated ASIC Quality calculation formula that makes reading on NVIDIA GPUs more reliable.

Other important updates include voltage monitoring support for Radeon HD 7970 and HD 7950; support for some rare GeForce GT 520 variants that are based on GF108, GeForce GTX 555 (OEM), GeForce 305M, and GeForce 610M; and more reliable memory size reading for AMD Radeon graphics cards with large memory sizes. Sensors now refresh in the background by default (and not just when the Sensors tab is in the foreground). The board ID is now displayed along with the BIOS version string.DOWNLOAD: TechPowerUp GPU-Z 0.5.9 | TechPowerUp GPU-Z 0.5.9 ASUS ROG-Themed

The complete change-log detailing even more updates follows.

Here is the first GPU-Z screenshot of a Radeon HD 7950 graphics card. Although put into a screenshot with ASUS GPU Tweak tool and Republic of Gamers-themed GPU-Z, the card doesn't appear to be an ASUS-made one, and is more likely HIS or PowerColor. The device ID checks out with the one HD 7950 has been associated with. Most other features match expectations. The HD 7950 is carved out of the 28 nm "Tahiti" GPU, with 28 GCN compute units (CUs) active, totaling 1,792 stream processors and 112 TMUs. The ROP count is untouched at 32, so is the memory, that's 3 GB GDDR5 across a 384-bit wide memory interface. With a memory clock of 5.00 GHz effective, it's churning out 240 GB/s of memory bandwidth. It's just the core clock speed where we weren't on target (from the previously-expected 800 MHz), either 880 MHz is the reference core clock speed of HD 7950, or this particular card is a factory-OC variant (PowerColor HD 7950 PCS?).

TechPowerUp today released the latest version of GPU-Z, our popular video subsystem information and diagnostic utility that provides you with accurate information about the graphics hardware installed, and lets you monitor their clock speeds, fan speeds, voltages, VRAM consumption, etc., in real-time. Version 0.5.8 introduces two new features. The first one is a render test that applies sufficient load (not stress) on the GPU to pull it out of PCI-Express link-state power-management, to ensure the Bus information is accurate. If you find the PCI-Express bus link speed or PCIe version displayed incorrectly, simply click on the "?" button next to the field to launch the load test.

The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.DOWNLOAD: TechPowerUp GPU-Z 0.5.8, TechPowerUp GPU-Z 0.5.8 ASUS ROG Themed

The full change-log follows.

If you thought the overclocking and benchmark feats we reported on a few days ago here and here were impressive, wait until you see what four cards can do. Overclocking champion Shamino over at Kingpin Cooling has set four 3DMark and one Unigene benchmark record:

Welcome to the first TechPowerUp news post of 2012! Read on for a couple of impressive overclocking feats with the HD 7970 graphics card.

It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest - excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.

VR-Zone have spent the New Year weekend overclocking this beast, having reached a whopping 1.26 GHz core clock speed with their HD 7970 - and decent benchmark improvements to go with it. Also, with the fan at 100%, the card never got above a very comfortable 68 degrees centigrade while running Furmark, which is amazing considering how this test is specifically designed to heat a graphics card to the max - but please see the update at the bottom of the article. The stock cooler may be noisy, but it's certainly very effective: an excellent result which will prolong the working life of the card.

TechPowerUp today released GPU-Z version 0.5.7, the latest version of our popular graphics system information and diagnostic utility. This release of GPU-Z comes just in time for the launch of AMD's Radeon HD 7000 series. It packs tested support for Radeon HD 7970 and HD 7350. It packs an updated PCI Express 3.0 detection routine, with better detection reliability. It fixes a bug related to "APIC counter broken" on AMD Fusion APU platforms. Detection is improved for some rare GPUs, such as HD 6450A, HD 6470M, and the more popular HD 5570.

Several reliability updates were introduced. This includes fixed (improved) fillrate calculation on Fermi architecture, fixed ROP count on GT 420, GT 520, HD 5450, HD 6450; fixed random values showing as default clocks on some NVIDIA cards; fixed random value showing as shader clock on NVIDIA cards without shader clock; and addition of process size, die size, transistor count for Radeon E6760.DOWNLOAD: TechPowerUp GPU-Z 0.5.7 and TechPowerUp GPU-Z 0.5.7 ROG-Themed

TechPowerUp released a new version of GPU-Z, version 0.5.6. GPU-Z is our popular graphics card information and diagnostic utility that gives you technical details of the graphics hardware installed in your PC, and lets you monitor fine details such as clock speeds, temperatures, and voltages. The new version adds preliminary support for some of NVIDIA's upcoming GeForce Kepler family GPUs. It also adds support for NVIDIA GeForce GTX 560 Ti 448 CUDA cores, which will be launched this 29th. Support is also added for AMD Radeon HD 6320, FirePro V9800, FirePro V4900, GeForce GTX 460 V2 (GTX 460 based on GF114), Quadro NVS 420, Quadro NVS 450, and Quadro FX 380 LP. A small bug related to incorrect shader reading on "Blackcomb" is fixed.DOWNLOAD: TechPowerUp GPU-Z 0.5.6 | GPU-Z 0.5.6 ASUS ROG Edition

A complete list of changes with this version follows.

The enthusiast community's favourite trial-by-fire for graphics cards, FurMark, has been updated to versions 1.8.5 and 1.9.1. Its developers maintain two branch versions of the program, since version 1.8 is popular, and 1.9 is the latest, bleeding-edge in the suite of stress test routines it has. FurMark is an OpenGL-based 3D graphics hardware stress-testing and benchmarking program. Its stress-testing functions are widely used to test stability of overclocked graphics hardware, and is dreaded by GPU manufacturers.

Version 1.8.5 is a maintenance release, which packs improved score submission, an updated number of window resolutions available, and improved graphics hardware detection using an updated ZoomGPU code. The FurMark 1.7 mode is removed. A bugfix filters the spikes in temperature graphs. Minimizing the window now can't be done in full-screen mode. Version 1.9.1, on the other hand, adds support for new AMD and NVIDIA GPUs with updated detection code, supports GPU-Z 0.5.1 and GPU Shark 0.5.1; added a workaround for a bug in AMD Catalyst GLSL compiler, which led to wrong lighting of the furry donut.DOWNLOAD: FurMark 1.8.5 and 1.9.1

A list of changes follows.

NVIDIA shook the high-end PC hardware industry earlier this month with the surprise launch of its GeForce GTX 580 graphics card, which extended the lead for single-GPU performance NVIDIA has been holding. It also managed to come up with some great performance per Watt improvements over the previous generation. The reference design board, however, made use of a clock speed throttling logic which reduced clock speeds when an extremely demanding 3D application such as Furmark or OCCT is run. While this is a novel way to protect components saving consumers from potentially permanent damage to the hardware, it does come as a gripe to expert users, enthusiasts and overclockers, who know what they're doing.

GPU-Z developer and our boss W1zzard has devised a way to make disabling this protection accessible to everyone (who knows what he's dealing with), and came up with a nifty new feature for GPU-Z, our popular GPU diagnostics and monitoring utility, that can disable the speed throttling mechanism. It is a new command-line argument for GPU-Z, that's "/GTX580OCP". Start the GPU-Z executable (within Windows, using Command Prompt or shortcut), using that argument, and it will disable the clock speed throttling mechanism. For example, "X:\gpuz.exe /GTX580OCP" It will stay disabled for the remainder of the session, you can close GPU-Z. It will be enabled again on the next boot.

On the eve of a big development in the GPU industry, TechPowerUp introduced the latest version of GPU-Z, the popular graphics subsystem diagnostic utility that provides you with detailed tech-specs of your installed graphics processors, and lets you monitor clock speeds, voltages, temperatures and fan speeds. Version 0.4.8 features support for new GPUs, most notably, full support for the NVIDIA GeForce GTX 580, support for some upcoming GF104-based consumer SKUs, and some handy stability updates.

Apart from the GeForce GTX 580, GPU-Z 0.4.8 supports GeForce GT 420 and GT 440 (which are currently OEM-only products). It also features an updated TMU and texture fill-rate calculation method, and updated reliability on ATI cards using certain unsupported kinds of voltage controllers.DOWNLOAD: TechPowerUp GPU-Z 0.4.8
