Salutare tuturor! Bine v-am regasit la un nou review!

De data aceasta am ales sa mai diversific putin lucrurile, asa ca am decis sa testez o placa video mainstream, din seria RV7xx de la Ati, serie ce momentan dispune de o gama larga de placi video (de la Entry-Level la Enthusiast), toate cu un raport calitate pret foarte bun.

In acest review va voi prezenta placa video Sapphire Radeon HD4670, oferita spre testare prin amabilitatea PCGarage.

2. Specificatii.

Procesor Grafic: RV730;

Proces Fabricatie: 55nm;

Frecventa GPU: 750Mhz;

Frecventa memorie: 1000Mhz (2000DDR);

Procesoare Stream: 320;

Bus: 128 Biti;

Cantitate Memorie: 512Mb GDDR3;

Interfata magistrala: PCI-Express 2.0;

Conectori: 2xDVI, 1x S-Video + 1xHDMI (prin adaptor);

Cooler: Single Slot;

Si pentru ca placa video face parte tot din seria RV7xx de la AMD ATI, regasim si aici aceeasi arhitectura foarte buna pe care o regasim si la fratii si surorile ei mai mari, ATI HD4830, 4850 si 4870, numai ca in cazul acestei placi, avem doar 320SP-uri, fata de 640 cate avem la HD4830 si 800 cate avem la HD4870.

3. Ambalajul si bundle-ul.

4. Closer Look.

Dupa cum se poate observa si din imagini, placa video este una destul de mica. Iar datorita procesului de fabricatie de 55nm, aceasta placa grafica consuma foarte putin, si nu are nevoie de nici o alimentare suplimentara, slotul PCI-Express fiind suficient pentru a alimenta placa video in mod corespunzator.

Sapphire HD4670 512Mb Review-p1030580.jpgSapphire HD4670 512Mb Review-p1030569.jpgSapphire HD4670 512Mb Review-p1030589.jpgSapphire HD4670 512Mb Review-p1030593.jpgSapphire HD4670 512Mb Review-p1030588.jpg

Sapphire HD4670 dispune de doi conectori CorssfireX, fapt ce permite realizarea unui sistem CrossfireX cu mai mult de 2 placi grafice de acest tip.

Sistemul de racire este unul simplu, redus ca dimensiuni, ce consta intr-un ventilator si un heatsink de aluminiu, prin care circula aerul, impins de catre fan.

Din pacate, memoriile Hynix (1ns, 2000Mhz) si VRM-ul, nu sunt acoperite de catre radiator.

Si o mica, comparatie (din punct de vedere al dimensiunilor), cu un Sapphire HD4850 (versiunea de referinta).

6. Temperaturi, Overclock si problemele intampinate.

Desi heatsinkul este unul foarte mic, acesta nu are nici o problema in a tine placa video rece. Totusi, solutia de racire aleasa de producator este foarte zgomotoasa, chiar si in idle. Si ca sa va faceti o idee, aceasta este mai zgomotoasa decat cea de pe orice HD4850 stock.

Initial am folosit Catalyst 8.11 pentru efectuarea testelor, dar cand am ajuns la capitolul numit overclocking, am descoperit ca mai toate programele cu care se poate efectua acest procedeu, nu functioneaza in mod corect cu aceasta versiune de driver. Astfel, eram nevoit sa folosesc Catalyst Control Center, care limiteaza posibilitatile de overclock la GPU la 778 Mhz.

Asa ca am instalat driverele Catalyst 8.10, acestea neavand nici o problema cu Riva Tuner, AMD GPU Clock Tool, sau ATI Tray Tools.

Pentru a overclocka placa video am folosit Riva Tuner 2.11, iar pentru a testa stabilitatea placii grafice in overclock am folosit Furmark Stability Test, ATI Tool si 3dMark 06.

In overclock placa s-a descurcat surpinzator de bine, desi racirea nu este una extraordinara.

Desi placa video a rulat foarte bine pentru aproximativ 30 min Furmark Stability test, la o frecventa a memoriilor de 1150 Mhz, in 3dMark06 au aparut artefacte.

Sapphire HD4670 512Mb Review-oc.png

Am obtinut in conditii de stabilitate perfecta 803 Mhz la GPU (750Mhz Stock) si 1101 Mhz la Memorii (1000 Stock). Avem astfel o crestere de 50Mhz la GPU si 100 Mhz (200 Mhz DDR) la Memorii.

Temperaturile se prezinta in felul urmator.

9. Far Cry 2.

Datorita Engine-ului Grafic (Dunia) foarte aratos, acest joc prezinta si niste cerinte destul de mari, dar potrivite totusi pentru hardware-ului anului 2008. Asa ca am decis sa testez aceasta placa video si in Far Cry 2, folosind utilitarul inclus in joc.

Am decis sa postez doar testele unde jocul este jucabil si prezinta un framerate cat de cat fluent. Asfel, pentru rezolutia de 1680x1050, am postat doar rezultate cu detaliile setate pe High (DX9 si DX10).

Teste DX9.0c.

Sapphire HD4670 512Mb Review-fc2_dx9.png

Teste DX10.


Sapphire HD4670 512Mb Review-fc2_dx10.png

Si pentru ca ziceam ceva mai sus ca Ati a lansat noile sale drivere, 8.11, ce promit cresteri de framerate de pana la 10% in Far Cry 2, am considerat sa realizez si un comparativ, 8.10 vs. 8.11.

Teste 1280x1024.

Sapphire HD4670 512Mb Review-fc2_10vs11.png

Teste 1680x1050.

Sapphire HD4670 512Mb Review-fc2_10vs11_1680.png

Dupa cum se poate observa si din teste, la o rezolutie de 1280x1024, Far Cry 2 nu reprezinta o problema pentru aceasta placa video, aceasta prezentand un framerate fluent, chiar si pe detalii Ultra High.

10. Crysis Warhead.

Nu putea sa lipseasca acest joc din teste, nu? Desi in rezultatele din teste am avut un average de sub 30 fps, pot sa va spun sincer ca jocul prezinta un framerate foarte fluent, si este perfect jucabil, pe 1280x1024, Gamer, DX9. Si asta pe o placa video de doar 315 ron.

Am facut doar cateva teste in 1680x1050, suficient cat sa imi dau seama ca nu are rost sa mai continui, deoarece nu o sa foloseasca nimeni aceasta placa video pentru a rula un slideshow... Asadar, am decis sa postez doar rezultate cu teste realizate la o rezolutie mai potrivita pentru aceasta placa video.

11. Race Driver GRID.

Race Driver Grid, un joc superb de racing, cu o optimizare pe masura. Dar sa vedem, se descurca HD4670 si aici la fel de bine ca si in testele anterioare?

In acest test, toate detaliile au fost impinse la maximum (in afara de MSAA, care in unele teste a fost dezactivat).

Sapphire HD4670 512Mb Review-grid.png

Ei bine, dupa cum puteti observa si din grafic, HD4670 nu se descurca la fel de bine si aici, ci mult mai bine. Jocul a rulat perfect si cu detaliile impinse la maximum, si 4XMSAA, la 1680x1050. Pot spune ca am ramas impresionat.

12. Call Of Duty 5 – World At War.

Dupa luptele moderne de anul trecut, din mult aclamatul Call Of Duty - Modern Warfare, seria COD s-a intors la cel de-al Doilea Razboi Mondial, odata cu noul Call of Duty 5 - World at War. Am ales sa includ si acest joc in teste deoarece engine-ul grafic folosit dispune de tehnologii noi, si arata foarte bine, fiind in acelasi timp si foarte bine optimizat.

Ei bine, sa vedem ce stie Radeon HD4670 in Call of Duty World at War. Texturile au fost setate manual pe Extra, iar toate celelalte detalii au fost impinse catre maximumul permis de joc.

Sapphire HD4670 512Mb Review-cod5.png

Impresionant, nu? Inca un test in care am ramas placut impresionat de performantele acestei placi video.

13. Pro’s and Con’s.

Pro’s

- Raport pret/performante excelent;
- Consum foarte mic;
- Posibilitate buna de overclock;
- Port HDMI cu posibilitate de redare sunet 7.1;
- Decodor UVD 2.0;
- Conector Crossfire X.

Con’s

- Bundle nu prea generos;
- Solutie de racire foarte zgomotoasa (chiar si in idle).

14. Concluzie.

Acestea fiind spuse, concluzia este una simpla. Daca doriti o placa video ieftina, dar vreti sa rulati si ceva jocuri, aceasta placa video reprezinta o optiune demna de luat in considerare. La aproximativ 315 ron, practic va alegeti cu o "mica bestiuta", cu care puteti juca aproape orice joc la 1280x1024, cu detaliile impinse spre maximum, chiar si cu AA si AF activate.


Nota finala: 9.

Rating: Silver Award / Best Budget / Best Buy !

Super placa, best bai. madace, sincer, nu-mi plac graficele. Ai incercat ceva nou, dar nu a iesit. In rest foarte bun review.
Daca-i asa zgomotoasa, n-as lua-o. Dar, nu se poate modifica turatia? Dar ar creste temperatura, oare cu cat?
