1 Blu-ray drive and HD capable monitor required.
2 Requires a 10-bit display
3 The ATI Radeon™ HD 4550 delivers 96 GigaFLOPS compared with the ATI Radeon HD 3450 which delivers 48 GigaFLOPS.
4 ATI CrossFireX™ technology requires an ATI CrossFireX Ready motherboard and may require a specialized power supply.
5 The ATI Radeon HD 4550 GPUs can upscale video display to 2560x1600 on dual-link monitors which is almost twice the display resolution of 1080p displays.
6 Over a one year period the ATI Radeon™ HD 4550 consumes 113.88 watts of energy in comparison with the ATI Radeon HD 3650 D2 which consumes 283.24 watts of energy based on the following calculations:
ATI Radeon HD 4550: 73 watts per year (8 hours a day at maximum power) + 40.88 watts per year (16 hours a day at idle)
ATI Radeon HD 3650: 195.64 watts per year (8 hours a day at maximum power) + 87.6 watts per year (16 hours a day at idle)
This results in an expected energy savings of 169.36 watts for the ATI Radeon HD 4550. This may differ paces on the amount of time your computer is on and the percentage of time it is under full load.

[Galai]

eheh subito prontissimo

[War_Wolf]

WOW
Qualcuno sa dirmi +/- quanto verranno a costare?

[diegofio]

sostituiranno le 3800 quindi siamo nella fascia media

[War_Wolf]

quindi nn le venderanno più quelle della serie 3800?

[Ibanez89]

le gddr5 promettono bene

[diegofio]

quindi nn le venderanno più quelle della serie 3800?

se escono queste progressivamente non verranno più vendute
comunque si tratta ancora di indiscrezioni ma ati deve rinnovare la fascia media soprattutto tra la 3870 e la 3870 x2 c'è un buco, magari aggiustano i prezzi

[Ibanez89]

certo però è un tempo d'oro per farsi il pc, ram le buttano dietro la schiena vga fascia media a prezzi decenti e cpu con i saldi...

[Galai]

si è vero.. sull'usato gli 8x00 si trovano a buoni prezzi..

[diegofio]

aggiunta 4870 x2 e aggiornate le specifiche

[vodka]

salve a tutti , io mi son appena acchiappato una 8800 gts della gigabyte ma nn ne son alquanto convinto in termini di immagine, le ati sembravano aver qualcosa in + , ma nn nei giochi , ... imho dite che se ritorno ad ati con una di queste una 4800 , faccio bene o rimango con la mia 8800 gts 512 mb !!
anche xkè adesso il discorso , che fabbricheranno nn + cpu + gpu.............. ma un bel VGPU ad ...octocore !!!
fonti

[diegofio]

chi può dirlo devono ancora uscire sulle prestazioni non si sa nulla
per la vgpu ne parleremo tra qualche tempo non in questa serie

[=Snake=(ITA)=]

certo però è un tempo d'oro per farsi il pc, ram le buttano dietro la schiena vga fascia media a prezzi decenti e cpu con i saldi...

Lo so che è un tempo d'oro comunque beh, direi che con la 4870x2 crysis non avrà problemi no apparte gli scherzi, si sa qualcosa sui consumi di queste schede video?

[diegofio]

c'e' scritto fratello

[=Snake=(ITA)=]

Ops sry, mi era sfuggito come puoi già immaginare ho la bava per la HD4870 X2 ehehehe
