The theoretical performance in FP32 is about 1.28 TFlops, which is quite good for a card approaching 7 years old. The peak fill rate is 16 GPix / s or 40 GTex / s. With these parameters, the memory bandwidth is about 72 GB / s.
This video card is based on the Capo Verde XT chip containing 1.5 billion transistors. The crystal area is 123 sq. mm. The card uses 1GB GDDR5 memory clocked at 1125 MHz (4500 MHz effective). The width of the data bus is 128 bits. Until now, 7770 cards can be found on sale, mainly in the secondary market. However, taking into account the fact that there are also new ones, we can conclude that the model turned out to be quite “tenacious”, despite the age of seven (the date of the map was released on ).
The Radeon HD 7770 was arguably the most popular in the entire 77xx line, as it combined sufficient performance at an affordable price. At the time of release, the price for one shader (UWB) was about $ 0.19 and was the lowest in the entire 77xx series. There were also minor differences in the series. So the chip frequencies in the 30th and 50th models were artificially lowered to 800 MHz (instead of 1000 MHz in the 70th and 90th models). In addition, 7790-based cards had 33% faster memory (1500 MHz instead of 1125 MHz).įor the rest of the characteristics, the adapters under consideration were absolutely identical.

So the 7700 series video adapters had the following core configurations: The main contribution to performance is made by UWB.

power consumption – from 47 to 85 watts.Īt the time of its appearance, these cards met the most modern requirements for hardware and software compatibility with all existing means for creating computing systems at that time.hardware API support – Direct X 11.1, partially 12.0 OpenGl – 4.2 OpenCl – 1.2.Overclocking AMD Radeon HD 7700 series AMD Radeon HD 7700 series specificationsĪMD Radeon HD 7700 series cards have the following features:.Radeon HD 7700 Series Graphics Accelerators.AMD Radeon HD 7700 series specifications.Therefore, until now, many AMD fans recall with horror the period when, having confused only two digits in the adapter index, it was possible to seriously miscalculate the performance. For example, the performance of the 79 differed by more than three times and the performances of the 77 were almost the same. To some extent, this made the 7700 series universal, since, on the one hand, the buyer could choose the performance he was interested in by purchasing a particular adapter. On the other hand, the presence of as many as 4 models with the same filling made a lot of confusion in the classification of video adapters.Ī similar confusion persisted in the next generation of AMD products – the R200 family, and only a couple of years later, with the advent of the R400, the situation with the classification improved markedly. Thanks to the modern 6nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks (depending on the CPU model).The explanation was quite simple: the models differed significantly in the number of unified shader processors. Of the entire HD 7xxx series, only the 7700 had this feature.

According to AMD, the Radeon 680M (in the 6800U) is faster than a dedicated Nvidia GeForce MX450 and best suited for 1080p gaming and low details (for AAA games). Compared to the dedicated Radeon 5300M (also RDNA), the 680M should still be significantly slower. Therefore, the 680M should be the fastest integrated graphics card in early 2022.
Thanks to the new architecture, high core count and the increased maximum core clock, the Radeon 680M should be clearly faster then the old Radeon Vega 8 iGPUs. The 680M and 660M iGPUs are the first integrated graphics card with hardware raytracing support, although the performance is too slow to use it in current games. The GPU is based on the RDNA2 architecture and has 12 CUs (= 768 shaders) clocked at up to 2,400 MHz (depending on the CPU model). The AMD Radeon 680M is an integrated GPU in the Ryzen 6000 series for laptops (Rembrandt, e.g.
