Inače do sada a i nadalje sam veliki zagovornik ATI-ja. Najviše je tome pridonjelo druženje s ATI-ijem kroz generacije modela i razne igre. Sjećam se moje prve 9600XT koja mi je priuštila prva iskustva sa igrama na računalu. Slijedio je solidan redosljed nasljednika X850 pa X1850 pa prve hd grafike HD2800, HD3870X2 (koju nikada neću prežaliti),

HD4850 dvije u crossfire modu pa na kraju  jedna HD4850. Proizvođači su se mjenjali ali je uvijek bio ATI.  Sada sam odabrao HD5770. Ponukan DX11 igrama (Dirt2) i razmišljanjima o budućnosti uzeo sam novu generaciju grafike. Koja možda malo kaska za HD4890 ali taman koliko kaska toliko je i jeftinija. Inače ako niste razmišljali o tome 4800 serija od ATI-ja je trošila poprilično struje, dok nova generacija je učinkovitija s manje energije, manje je zagrijavanje. Definitivno kako je rekao prokomentirao čovjek kod kojeg sam kupovao grafiku:

“ Gle, koju god uzeo pogriješio si. Sada je 4870 i 4890 u vrhuncu, a cijena je fantastična, nove 5770 i 5870 su  skuplje ali nose DX11, imaju manju potrošnju energije, manje zagrijavanje, i u svakom slučaju nova tehnologija.“

Izbor ostaje na svakome pojedinačno da li se odlučivati za novu genraciju 5800 ili 5700 ili stariju 4800 ali koja još uvijek dobrano drma.

No primimo se HD5770. Po meni ulazna gamer grafika nove ATI generacije, cijenom izrazito prihvatljiva u odnosu na performanse. Cijena od cca 1200-1300kn je dobar omjer uloženog dobivenog. Rađena je da bude mlađi brat HD5870. Priča se po netu da je 5770 uštopana od strane ATI-ja kako ne bih bila konkurrencija 5870 modelu koji je poprilično skuplji od nje. Zasnovana je također na novom 40nm čipu koji se  razvio te nas u zadnje vrijeme  proizvođači zatrpavaju novim modelima sa DX11 tehnologijom. HD5770 bude dolazila dvjema inačicama.Prva 512mb DDR5 i druga 1gb DDR5. Slično kao 4870 kada je došla. ATI je sa ovim modelom učinio DX11 grafike prihvatljivima širokom puku. Otežao nam je odabir jer za neznatno više novca imamo novu generaciju grafike. Inače poprilično zgodna stvar su izlazi. Zato što možete prikazivati sliku na tri ekrana. Korisno ne samo za gamere nego i web dizajnere, projektante i slčne korisnike koji koriste više displaya. Na kraju se sve svodi na osobni odabir. Razmislite ozbiljno o nabavi HD5770 ako kupujete novu grafiku.

Bus Type

PCI-E 2.0 

GPU Clock MHz

The main attributes of the GPU are the core clock rate, which typically ranges from 250 MHz to 1200 MHz.  850 - 875 MHz 

Stream Processors

Through the use of stream processing, computer benefit from the ability to transparently access a large number of 'cores' (or, computational units) on a chip without having to separately manage each and every one of them along with their associated busses, memories, I/O, etc.  800 

Memory Interface Bus (bit)

The bit data rate between memory and the GPU.  128 

Memory Type

VRAM was typically based on DDR technology. During and after that year, manufacturers moved towards the vastly superior DDR2, GDDR3 and GDDR4.  DDR5 

Memory Size (MB)

the video card will have its own video memory which is called Video RAM or VRAM. The VRAM capacity of most modern video cards range from 128 MB to 2.0 GB.  1024 MB 

Memory Clock (MHz)

The memory clock rate in modern cards are generally between 400 MHz and 2.4 GHz.  4800 - 5200 MHz 

Microsoft® DirectX® Support

The standard for today's PCs and next-generation consoles enables stunning and complex effects for cinematic realism. XFX graphics cards offer the most complete implementation of the Shader Model feature set-including vertex texture fetch (VTF)-to ensure top-notch compatibility and performance for all DirectX applications.  11 

Shader Model Support

Enables stunning and complex special effects. Next-generation shader architecture delivers faster and smoother gameplay.  5.0 

Open GL Optimization and Support

Ensures top-notch compatibility and performance for OpenGL applications.  3.2 

Minimum Power Requirement (Watt)

This is the minimum power supply wattage requirement for the graphics card to perform properly.  450W with one 6-pin power cable 

Cooling Fansink

Sometimes known as an active cooling device, a small electrical fan which drives air across a heat sink and as such will generate a small amount of noise. It is more effective than a heat sink alone at cooling.  √ 

ROHS

The RoHS Directive stands for "the restriction of the use of certain hazardous substances in electrical and electronic equipment". This Directive bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.  √ 

Profile

Some graphics cards have the capability to swap out the current bracket to make it compatible with low-profile computer systems that require a lower bracket card.  Double 

ATI Radeon CrossFireX™ Technology

ATI CrossFireX™Technology with up to quad GPU support offers superior scalability so your system is ready to level up when you are.  √ 

ATI Radeon PowerPlay™

Advanced power management technology for optimal performance and power savings. Performance-on-Demand allows you to constantly monitor GPU activity and dynamically adjust clocks and voltage based on user scenarios.  √ 

ATI Radeon Stream Technology

ATI Radeon Stream technology is a set of advanced hardware and software technologies that enable AMD graphics processors (GPU), working in concert with the system’s central processor (CPU), to accelerate many applications beyond just graphics.
