AMD has announced the introduction of its whole Radeon HD 7000 GPU family in the coming months, following the successful launch of its first 28nm GPU in January. Following the announcement of Nvidia’s upcoming flagship, the GeForce GTX 680, the Radeon HD 7870 looks very closely at the latest 7850 graphics cards in the series.
By ripping off the Radeon HD 7970, the GTX 680 nicknamed Kepler quickly became the ‘s tallest single GPU solution. AMD attempted to cushion the impact by slashing the pricing of its 7900 and 7800 series processors. But, in the end, the biggest news for AMD was the nearly total stock decrease of the GTX 680.
LGA 1155 motherboards are no longer in production and most of them have been sold out. You can’t run DDR4 memory on them anyway. If you want to upgrade you’ll have to switch processors as well. Read our article on Best LGA 1155 Motherboards to get your hands on if not best then one of the best motherboards that you can use with 1155 Motherboards.
Nvidia’s top Radeon HD 7970
In fact, finding a GeForce GTX 680 now is difficult, especially for those willing to pay more than the $499 stated price. Two months later, the Nvidia GeForce GTX 670 was released at a very affordable price of 39 399 dollars. At this pricing, the GTX 670 offers the same performance level as the Radeon HD 7970 at a lower cost.
However, Nvidia’s top Radeon HD 7970 was 5 percent faster on average, with certain bright spots of up to 30 percent faster. That is why it has fallen in price from $ 7970 to $ 449.
Fast forward to today, and it appears like AMD no longer has the right to be proud about getting GPU money on the cheap. The Radeon HD 7970 GHz edition, as the name suggests, runs at 1500MHz with a 1GHz core clock speed and overclocked GDDR5 memory. AMD intends to charge $ 499 extra for GHz cards, but is it justified?
7970 GHz is a more detailed version of 7970 GHz
There’s nothing new here for those who are acquainted with the Radeon HD 7970. It’s essentially the same graphics card, but with some manufacturer overclocking as well as a higher price.
While the used CPU prices continue to drop, used motherboard prices can stagnate or actually go up, especially for AM3+ motherboards. Our article on the Best Budget AM3+ Motherboard can lead you to not only the finest but one of the most affordable am3+ motherboards.
The GHz edition of the Radeon HD 7970 graphics cards has a core clock of 1000MHz and a memory frequency of 1500MHz, whereas the normal version has a core clock of 925MHz and a storage frequency of 1375MHz. That’s an increase of 8% in core overclocking and 9% in memory overclocking, which isn’t quite the same as the price increase of 11% over the normal HD 7970 card.
Surprisingly, Radeon HD 7970 cards with clock speeds of 1GHz and higher are currently available from the factory. The PowerColor PCS + AX7970 has a clock rate of 1.1GHz (core) and 1425MHz memory, and it costs only $ 490.
AMD feels that such a small change will be sufficient to beat the GeForce GTX 680, and we’ll discover that today.
Updated technical features.
The new Radeon HD 7970 1GHz Edition may not be as exciting for those who have purchased the previous AMD option, largely because their investment may have been underestimated, but it is a direct comparison to AMD’s products. Enough to defend against. In our reviews, the Radeon HD 7970 was a card that held on until it was given enough CPU power and used high resolutions with screen filters that outperformed the GTX 680. Took advantage of more bandwidth. Thus, he defended himself really well, passing many of our usual battery test tests.
The card also maintains its overall computing capacity at more than twice as fast as the GTX 680. This 1Tflop is capable of generating dual precision computing power that requires power for both gaming and gaming. Multimedia and professional applications where, for example, Photoshop CS6 is prominent. In fact, any program with good support from OpenCL will have an exceptional company in Radeon 7970 that will clearly and distinctly improve the performance of its applications.
Consumption and noise.
Now, the Geforce GTX 680 is undoubtedly a more efficient card, and I don’t mean cheap, because it produces more or less performance with less use. It’s a fact that now that AMD wants to compete, the GTX 680 has no choice but to compete in terms of performance. The new Radeon HD 7970 1GHz Edition is not a cooler card, it uses more than the previous card, and even its fan turbine (reference model) has more capacity than the Rio and if we put it under extraordinary load. If so, it makes more noise.
The card, like the previous model, requires an 8-pin and 6-pin PEG connection to be fully ready to offer the card’s 232w TDP with very little input from the motherboard’s PEG slot.
Software and drivers
Software and drivers. Six months have passed since the release of Radeon HD 7970. Six months of driver development and new software releases that make the most of AMD’s GCN architecture. OpenCL support for this architecture is exceptional, the power of computing is amazing, and it translates into more mature drivers with faster development in programs and better engagement at the level of games and software.
The first instance of driver changes is found in the more controlled and simple configuration of multiple monitors or in the new dynamic overclocking modes that allow this card, for example, its nominal without much interference. Can convert GHz frequency to 1.05GHz frequency. The card is TDP and dynamically controlled directly in the driver.
In terms of overclocking, the reference version we’ve been able to test doesn’t have much GPU capability. Reaching 1100MHz was our limit, although for RAM we achieved a slight increase with the final frequency of 1600MHz producing a total of 6400Gbps, which gives a little more than 300GB / s bandwidth, which is a bit for the card. Extra performance. About 5%.Intel’s processors are known for overclocking, and if your main concern is to get the best overclocking performance on a reasonable budget, then the i5 6600k can be a wise choice. Read our article on the Best Motherboards for i5 6600k to find affordable yet feature-packed motherboards that you can use with i5 6600k.
We’ve made a small comparison of the results of the old Radeon HD 7970 with the Nvidia GTX 680 and of course added our own tests with the new Radeon HD 7970 1GHz edition. A test machine is a conventional machine with a Core i7-3960X processor with a working frequency of 4.5GHz. This way we ensure that the processor will not interfere with the testing of all graphic chips. Dragon Edge 2. 2560×1440 Maximum quality. FSAA 4x. AF 16x.
As long as you don’t have unrealistic expectations the 775 platforms can still hold their own and come at a very affordable price, not kidding. Look into Best LGA775 Motherboards and start playing A title games without breaking the bank.
Six months after its launch and three days after the Geforce GTX 680 challenged AMD’s GCN architecture, the new 1GHz edition arrived. This card regains the throne of performance of single-chip graphics cards with amazing performance but it does so without looking at usage and it keeps the Geforce GTX 680 as a more energy-efficient option. Obviously AMD, at the moment you no longer have to justify your card’s performance, this is again the best, although the truth is that any user of the previous model will be happier at home because it is Still a card with exceptional performance. Oh, by the way, prices have dropped with the new 1GHz edition at the recommended price of 469 euros.
