4750 nu a aparut, aia o sa fie un 4770 mai slab. dar nu sunt unul si acelasi lucru. bine, asa era vb, poate nu mai apare. oricum, 4770 merita din plin.

asculta ce zice eu
acel 4750 din review e actualul 4770,cu un GPU clock mai mare ca sa taie si mai tare din Nvidia ( "750 "early engineering", deci nu avea specificatiile finalizate,asa cum se deduce din text)

Meet the Radeon HD 4750

Okay then, you fine men and women would of course like to learn everything about this little silicon called RV740. So, we'll try to get you as much information as we can gather. But obviously we have only very limited information at hand.

A good way to explain a product is to always explain what it is not.

RV740 is not a high-end graphics card. In fact if the board partner that submitted this card is correct, it's pricing would be below 99 USD. That would make it fare into the budget segment. But it's not a budget product either.

The chip will be the successor to the RV730 (Radeon HD 4650/4670), although that product will still remain in the market for a while, we think, AMD can redefine the budget to middle class product line-up. See, performance of the strongest RV740 based product will move upwards in-between HD 4830 and HD 4850 performance.

It is a very spiffy card when it comes to performance (for the money of course). Here's what we know. RV740 has 640 shaders (stream processors). The core frequency for the early engineering sample card we tested is 650 MHz.

RV740 is based off a 40nm production node and is equipped with 128-bit memory. Now before your go "aaahw, we lost half the framebuffer bandwidth due to 128-bit memory", here's the thing. The RV740 is equipped with GDDR5 memory. This GDDR5 memory is running at 800 MHz, that would boil down to 3200 MHz, 3.2 Gbps effective... that's just over 50 GB/sec of bandwidth depending on the final memory configuration.

Now if you cut down the memory bus in half to 128-bit you lose half the bandwidth, ATI compensates for that by doubling it up again with GDDR5 memory. It's a bit of a tradeoff here and there. See, 128-bit memory is fairly cheap to use and does return a heap of framebuffer bandwidth thanks to the higher frequency memory. Also I can imagine a simpler design in the PCB such as using less wires and thus a cheaper design. On the flip side, slower memory latency timings. But granted, this choice makes a lot of sense, as the results will show.

Now I've fired off some math at the most generic denominators and when we place things in a chart, you'll gain some perspective of product differences.

The RV740 houses 640 stream processors, 32 texture memory units (TMUs) and 16 render output units (abbreviated as ROPs). As stated, It features a 128-bit wide bus using GDDR5 memory, bumping up bandwidth that rivals equally clocked GDDR3 with double the bus width. Very interesting.

Meet the Radeon HD 4770

So then, to understand what is powering up that Radeon HD 4770 first we need to learn what's inside it. The basis of the card is in essence the graphics processor and it's video memory, slapped onto a PCB with crystals, PLLs, voltage regulators, resistors, capacitors etc etc.

The GPU used on this card has the following codename -- RV740.

RV740 is the replacement of the RV730 (Radeon HD 4650/4670), that product line will still remain in the market for a while, yet we think RV740 in time will replace it completely as this series is just too strong. Why you ask? Well, the RV740 is really a disciple of RV770, yes indeed... the Radeon HD 4850/4870.

By making this move, AMD slash ATI will redefine the budget to middle class product line-up as performance of the strongest RV740 based product will move upwards in-between the HD 4830 and horribly close to HD 4850 performance.

It is a very spiffy card when it comes to performance (for the money of course). Radeon HD 4770 has 640 shaders (stream processors). The final core frequency for the card we tested is 750 MHz.

RV740 is based off a 40nm production node and is equipped with 128-bit memory. Now before your go "aaahw, we lost half the framebuffer bandwidth due to 128-bit memory", here's the thing.

See, 128-bit memory is fairly cheap to use and does return a heap of framebuffer bandwidth thanks to the higher frequency memory. Also I can imagine a simpler design in the PCB such as using less wires and thus a cheaper design. On the flip side, gDDR5 does have somewhat slower memory latency timings. But granted, this choice makes a lot of sense, as the benchmark results will show.

Now I've fired off some math at the most generic denominators and when we place things in a chart, you'll gain some perspective of product differences.

Geek facts: the RV740 houses 640 stream processors, 32 texture memory units (TMUs) and 16 render output units (abbreviated as ROPs). As stated, It features a 128-bit wide bus using GDDR5 memory, bumping up bandwidth that rivals equally clocked GDDR3 with double the bus width producing 51.2 GB/s of memory bandwidth, and for a product like shown today... bandwidth is everything.

stiu chestiile astea, dar ei ziceau ca vor lansa ulterior lui 4770 un 4770 mai slab tactat, parca si cu gddr3 in loc de 5, pe care il vor intitula 4750. asa zicea la momentul ala o stire pe fudzilla. tu imi faci apologia aparitiei lui 4770. e ca atunci cand nvidia a tot scos dupa 8600 tot felul de mizerii, 8400, 8500 etc. cam asta ar fi un 4750. posibil sa aiba alt nume.

nu-ti fac nici o aplogie
la acel moment ( si in review-ul la care face el quote),4750 era aceeasi placa cu 4770 de azi

de curand au anuntat si 4750,cu DDR3,pe care eu nu l-am observat...imi cer scuze pt asta

de 4750 nu se stie nimic ca data din ce am citit eu

daca 4750 o sa aiba ddr3 si tot 640 sp-uri si bus tot de 128 de biti, o sa fie o prapastie de performanta intre 4750 si 4770. vom vedea...

Corect, ala e continuarea seriei de procesoare SPARC bazate pe arhitectura RISC si o sa ajunga in statiile de lucru si serverele de la Sun Microsistems sau Fujitsu, nicidecum in segmentul consumer si nici macar prosumer.

Tuniq revine in lupta cu T120-EX si se preconizeaza o noua schimbare in clasamentul coolerelor...
La ComputeX a fost dezvaluit urmasul lui Tuniq Tower 120, colerul care a tinult primul loc al topurilor o vreme destul de indelungata...
Tuniq T120-EX are in componenta 5 HP-uri duble (3x∅8mm si 2x∅6mm) cu doua mai mult decat Tower 120. Va fi compatibil cu LGA1366/775/K8. Dimensiunile lui vor fi 131 x 112.3 x150.7mm.
Un alt lucru bun va fi faptul ca, in cutie se va gasi si un tub de TX-3, noua pasta termoconductoare de la Tuniq.

Nici Noctua n-a stat degeaba si a prezentat la ComputeX cateva noutati.

Pentru început, au aratat o noua versiune a popularului NF-P12 , la care s-a adaugat functia PWM.
Tot cu PWM va fi si viitorul NF-P14, un ventilator de 14cm, optimizat pentru airflow puternic si zgomot redus. Pentru a asigura o rezistenta sporita, rama acestui ventilator va avea insertii metalice. Distanta dintre gaurile de prindere va fi identica cu cea a ventilatoarelor de 12cm deci va fi compatibil cu majoritatea radiatoarelor/carcaselor care suporta ventilatoare de 12.
Au mai fost prezentate doua modele de coolere in varianta retail, primul, NH-C12P SE14 fiind o varianta noua a lui NH-C12P, echipat acum cu noul ventilator de 14cm NF-P14, iar al doilea, un cooler complet nou si anume NH-D14, un radiator dual cu 6HP-uri duble, la care se pot monta 2 ventilatoare P14/P12 in sistem push-pull, unul fiind pozitionat in centru si unul lateral.
Piata server/workstation nu a fost nici ea uitat si i s-au pregatit noile versiuni ale seriei DX, NH-U12DX 1366 si NH-U9DX, compatibile acum cu noile Xeon 5500
Printre celelalte au fost deasemenea prezentate si sistemele de prindere SecuFirm2™, SecuFirm2™3-in-1 Intel Mounting System(comun pentru LGA1366, LGA1156 si LGA775) si SecuFirm2™ AMD Mounting System.

Fudzilla - ATI fixes HD 4770 supply issues with HD 4850

Quote:
According to what we have heard ATI is playing fair on this one, as it has promised a US $99 card that they simply could not deliver in volume due to low yields and high demand. In order to live up to its promise ATI has simply adjusted the price of the HD 4850 in order to keep its customers, if you want US $99 card, you can have the HD 4850.

AMD se pregateste sa lanseze PhenomII X4 965: "AMD plans to launch its new processor based on the Deneb core. It is named The Phenom II X4 965 ,which works at 3.40 GHz with 200MHz of FSB and 17.0x of multiplier. In comparison with 955 Black Edition,it gets 200MHz increase.

Whether 965 is black edition or not still confuses us. Its price is unknown. If launched as a Black Edition ,it could be priced above the 955 and replace 955 with price tag of $249.99. Without the BE branding it could be priced slightly lower.

The new processor will adopt AM3 interface,supporting DDR3 1333 MHz and DDR2 1066 MHz. The release of the RS880-based AMD 785G chipset will start at the same time with the new processor. As expected,AMD will dispatch samples next week."

kkt. pai mersi, racit la -200 grade normal ca ajunge. asa si 8400-le meu probabil ca sare lejer de 4.5 ghz, ca sa nu zic 5.5. cati useri au asa ceva acasa? numai solutia de racire costa de te indoaie. scuze daca o sa o percepi ca ma iau de tine, nu are nicio legatura. nu asa ceva intentionez.
