Beat the GeForce 9800GT and 9600GT

" It's also faster than the GeForce 9800 GT, by a significant amount in some cases, and doesn't lose a single benchmark to it......It's also the fastest of all in Enemy Territory " - Benchmark by Hexus.net

" Even at 1680x1050, we see HIS' Radeon HD 4770 snag a definitive victory over the GeForce 9800 GT, to the tune of over 40%. " - Benchmark by Elite Bastards

Benchmark provided by AMD

" In Stalker DirectX10.1 environment, cards calibrate excellently as well. Two HIS Radeon HD4770 achieved about 20% better results than GTX285 and GTX275.......In STALKER game the profit over a single card 4770 is very high. Performance gain is almost 200%! We can see unquestionable advantage over single card construction as well from similar price range.  " - Review by Benchmark.pl

" Looking at the comparison between the 4770 and 9800 GT we see once again that the ATI card is a better performer " - Benchmark by Driver Heaven

I just wanted to thank HIS for their efforts in maintaining a very strong and respected company. I recently purchased a 4770 off of newegg.com and since they were all identical I based my decision off, of all things, your website. I looked at other vendor websites and they all seemed to lack fluidity and ease of use. You have a great website and actually had drivers for the 4770 which others did not.

I upgraded from an NVIDIA 7600GT (I know, ancient card) and I could not be any more pleased. The price point, the quality, everything about this card is phenomenal.

Brand new architecture, GDDR5, lots of overhead for overclocking. The drivers come with an official program from ATI to OC your card, and I have that maxed out and it still runs cool, quiet, and stable. I know this card can be pushed further with third party software, but I am more than satisfied with my current settings.

Summary: This card is cool, quiet, and stable. It's a great deal and I highly recommend it, especially from HIS.

Double of these cards in CF mode beats gtx285 in most games and apps.

HIS has won over 1700 awards with AMD graphic solutions from major media worldwide.

PC Advisor

" The HIS Radeon HD 4770 has been nominated for ‘Best Graphics Card'. This is a real testament to the quality of graphics cards HIS produce and the progress the company has made. " - Nominees for PC Advisor's ‘Best Graphics Card

"  For any gamers or enthusiasts looking to spend under £100 on a graphics card I fully recommend you give the HIS 4770 a try. It offers performance which is on par with the 4850, although dropping slightly behind in the Anti-Aliasing department and comes in at £20 less. A saving I'm sure many will be happy with. " -  Techreviews 5-stars Award

" Very quiet cooling technology, very high efficiency - enough to able play in Full HD " - Chip Econo Award October 2009


HIS 4770 earns the MikroDatorn Recommended Award

Custom PC Approved Award

" The results of the tests with the HD 4770 were beyond our expectations, which were previously good. Its performance, for example, gets much closer to the performance of the HD4850 rather than the HD 4830, which HD 4770 is meant to substitute. It also proves ro be superior to GeForce 8800GT/9800GT and getting very close to GTS 250 in some cases. " - Review by Forumpcs Brazil

" The quake engine utilizes Open GL and the HIS HD4770 has an 11FPS lead over the Nvidia 8800GT....... This is an excellent card choice for multimedia and HD movie watching. If you're looking for a low budget gaming and multimedia card check out the HIS HD4770. " - Christ Centered Gamer

" In the 3DMark Vantage, the best program to evaluate the performance of  3D graphics card, the 4770 scored 7 019, while the 4850 scored 7 059. A GeForce 9800 GT lost far away from these numbers ...... In short,  the HD 4770 has performance of 4850 with 9600GT price, what, in our opinion makes it  a hit  in the market. " - Review by Info Online

" What really impressed me was Far Cry 2's showing. Far Cry 2 is fairly intensive and I fully expected the HD 4770 to struggle a bit with it. I was certainly surprised when a few tunes made the game flow like water......It's not all about horsepower however. The card's cooling system did an excellent job and was never audiable in a normal setting. " - Overclocker Cafe Editor's Choice

" With the two hardest tests out of the way, we were pleased to see that the HIS 4770 managed a playable frame rate (32fps) in Far Cry 2......Meanwhile, the 9800GT struggled to play Far Cry 2 at 1,280x1,024, with a poor minimum frame rate of just 24fps.......We could overclocked HIS 4770 to 895Mhz. These huge overclokcs show a lot of promise for the 40nm GPUs. " - Custom PC Approved Award

" HIS 4770 manages to make a mockery of Nividia in the mid-range too - it takes the 9800GT for a ride and even holds its own against the 9800GTX+ in places......ATI has cranked the GPU to the max for an excellent price-to-performance ratio " - Total PCGaming Editor's Choice

" The HD4770 is an excellent debut for 40nm graphics cards and is unmartched in its price bracket " - Personal Computer World's Great Value Award & Best Buy Award

HIS 4770 Video Review - 3Dgameman Great Gamer Pick Award

" That closeness in performance to the HD 4850 makes the ATI Radeon HD 4770 an outstanding card, given that it should sell for at least £50 less then the 4850. It's also cheaper in comparison with the 4830, despite being faster in most of our tests. This card redefines the sub-£100 arena and, as such, is a quite fantastic buy. " - PC Advisor Gold Award

" Looking at the comparison between the 4770 and 9800 GT we see once again that the ATI card is a better performer......The 4770 impressed us greatly, it offers good performance, excellent value and thanks to a decent cooler and the 40nm process they run at very low temperatures. " - Driver Heaven's Editor Choice

" With its efficient and noticeably quiet heatsink assembly, the 4770 will feel at home in any gamer's system. " - Overclock3D's Value for Money Award

" RADEON HD 4770 is twice as fast as NVIDIA GeForce 9800 GT (in pixel shader 4.0 benchamrk), and it's much faster than the HD 4830......Waves test results resemble what we saw last time. AMD products get even a bigger advantage here, now GeForce 9800 GT is up to 1.5 times as slow. The new RADEON HD 4700 looks good, outperforming its rival.......The card left a very good impression in general. Even if it was sometimes outperformed by competing products, we must admit that HD 4770 is faster than 9800 GT in most cases." - Review by IXBT Lab

" In this environment work tandem HD4770 satisfy almost the same power consumption as Radeon HD4890 and from 10 to 25W less than GTX275...... We have profit here even over 90%, superiority CrossFire HD4770 over Radeon HD4890 and GTX275 this is about 1000-1200pkt......In Stalker DirectX10.1 environment, cards calibrate excellently as well. Two Radeon HD4770 achieved about 20% better results than HD4890 and GTX275...... In Race Driver GRID game, HD4770 in CorssFire turned out that stronger solution than GTX275 and GTX285. " - Benchmark.pl's Super Product Award

" On the merit of performance and price, the HIS Radeon HD 4770 is definitely a very exciting graphics card. It delivers decent performance at a price too attractive to ignore. I suspect other manufacturers will soon be pushing their own HD 4770 cards ... but right now, HIS Radeon HD 4770 is one of the first to the market. " - CPU3D Recommended Awards (Scores 8 out of 10)

" Our benchmarks have shown the Radeon HD 4770 to be a surprisingly capable performer, laying down benchmark results that were on the high side of expectation. It's also faster than the GeForce 9800 GT, by a significant amount in some cases, and doesn't lose a single benchmark to it......It's also the fastest of all in Enemy Territory, where fillrate is king......HIS benefits from the HD 4770's price-to-performance excellence " - Hexus's Gaming Recommended Award

" Even at 1680x1050, we see HIS' Radeon HD 4770 snag a definitive victory over the GeForce 9800 GT, to the tune of over 40%......Thus, it's no surprise to see HIS's offering (complete with custom, dual slot cooling solution don't forget) wiping the floor with the GeForce 9800 GT in temperature terms - Its GPU runs around fifteen degrees cooler at idle, and over thirty degrees cooler under a 3D rendering workload.  The numbers speak for themselves, pure and simple..... It looks to be an extremely competitive price point against most GeForce 9800 GT boards. " - Elitebastards' Value Award
