Powercolor HD4850 Review: Priced for Gamers - 26-06-08, 14:19


Untuk pembuka review kali ini langsung saja kita ke sesi tabel spesifikasi HD4850, GPU keluarga mid-high baru dari DAMATI. Saya sertakan juga ke dalam spesifikasi table: RV670 Gladiator dan RV770 Trojan sebagai kakak dari RV770 Makedon.


Apa yang baru becc di RV770? Melihat spesifikasi RV670, maka saya akan mencoba mengupas sedikit tentang upgrade apa saja dibalik RV770.

320SP (64ALU x 5) -----> upgrade: 800SP (160ALU x 5)
Banyak amat 800SP? Aslinya Cuma 160 Stream Processor ala Nvidia kok. Sebenarnya gak bisa disamakan gitu, cuman maksa make bahasa marketing aja yang simple. Yep, 160ALU yang (bisa) menangani 5 perintah secara parallel sekali cycle. Hal ini punya dampak yang sangat “destroyer” terhadap kemampuan Shader-ing. Komparasi ada di table (satuan GFlops). Didapat dengan formula = SP x 2 x Core clock.

16TU -----> upgrade: 32TU
32TA -----> upgrade: 40TA
16TF -----> upgrade: 40TF
Untuk texture fillrate, akhirnya AMD/ATI membaca feedback email gwe dan email teman-teman untuk menambah Texture Unit, Texture Adress dan Texture Filter … Karena 16TU yang lalu di (X800, X1800, X1900, HD2900, HD3800) itu bener-bener beneran bikin bottleneck. Thanks ATI.

Gitu aja singkatnya, mari kita lanjutkan ke sesi poto-poto di tempat yang biasanya …

Test System
Maaf, karena ini rig saya juga baru saja ter-upgrade beberapa waktu lalu (pengen ngicipin processor 45nm ceritanya) … maka dengan ini saya TIDAK BISA membandingkan hasil benchmark HD4850 dengan arsip-arsip VGA yang pernah saya review. Karena mayoritas review yang lalu diselesaikan dengan E6300 @3.2GHz … she’s gone by the way *cough cough

So, here’s the mainstream rig to burn the baby:

- Epsilon 700W
- DFI LanParty DK P35 T2RS
- Xeon E3110 445x9 (4.0GHz)
- Ballistix 2GB 4:5 (1113MHz 5-5-5-15)
- BenQ FP201TW 1680x1050
- Windows XP Professional SP2 32bit
- Windows Vista Home Premium SP1 32bit
- GPU Driver Packaging Version: 8.50.3-080514a1-064602C-ATI
- Mouse, Keyboard, etc
- DX9: 3Dmark06, Racedriver Grid, Crysis
- DX10: 3DMark Vantage, Call of Juarez, World in Conflict




3DMark2006 dan 3DMark VantaT
Karena bukan processor Core Two Quad, ya dimaklumi aja hasil 3DMark2006 default bench 1280x1024. Tapi saya telah meng-highlight saat VGA lepas dari ketergantungan Processor dengan menaikkan resolusi dan penambahan beban AntiAliasing (AA)



3DMark Vantage... walau saya sebenarnya males banget ama graphic VantaT yang kurang candy untuk ukuran DX10 … what a big “candy” fail! Tapi ya (mungkin) karena dianggap mandatory oleh sebagian user, maka dengan ini saya sertakan 3DMark VantaT, ladies and gentleman …

E: 1024x768 Medium
P: 1280x1024 High
H: 1680x1050 High 2xAA
X: 1920x1200 Extreme 4xAA … (monitor enggak support, LoL)




Gaming DX9


Impressive …



Gaming DX10


Good deal …

Overclocking
Untuk Overclocking, dengan reference stock cooling ini saya hanya berani mencoba menarik core clock ke 700MHz dan memory clock ke DDR3 2000MHz dengan ATI Overdrive di Catalyst Control Center. Jika melihat kembali ke tabel spesifikasi terutama highlight bagian Theoritical Calculation, maka peningkatan core clock di HD4800 ini secara direct membuat 800SP 40TA/TF dan 16ROP gerah keringetan



Default:
- Core clock: 625MHz -----> 100%
- Memory clock: 1986MHz -----> 100%
- Performance: (MinFPS + AverageFPS + MaxFPS)/3 -----> 100%

Overclocked
- Core clock: 700MHz adalah 625MHz + 12%
- Memory clock: 2000MHz adalah 1986MHz + 1%
- Performance di WiC 1440x900 High 2xAA meningkat sebesar 9%


Temperature
Terkait dengan temperature, karena RivaTuner belum mengenali VGA baru ini maka saya memakai mode ALT+TAB. Dengan mengintip Catalyst Control Center (bagian Overdrive untuk mengetahui berapa current temperature). Lalu saat bermain aplikasi 3D dengan memainkan ALT+TAB.



Noise
Suara FAN dari reference cooling sangatlah menyenangkan. Gak make acara “nguing-nguing” saat GPU Full Load Putaran fan masuk kategori bravely silent in continuous spins … apaan tuh becc? Ya coba bikin kata baru aja, LoL, berputar dengan pasti secara terus menerus. Dan saya garansikan HD4850 ini lebih hening (jika dibandingkan HD3850 dan atau HD3870 reference cooling).

Verdict

Cocok buat anda yang memakai monitor 19” 1440x900 sampai dengan 22” 1680x1050 dengan Antialiasing, atau 1920x1900 24” tanpa Antialiasing.

Yang unik dan belum bisa saya investivigasi secara lebih mendalam adalah performa saat AA ON. Performa Antialiasing itu naik drastis dibandingkan dengan generasi HD2000 dan HD3000 terdahulu. AA itu digarap di departemen Stream Processor yang berjejal-jejal. Bukan di departemen Pixel Fillrate, yakni ROP (Render back end), yang seperti kita ketahui bahwasannya AA traditional dan ordinary digarap oleh ROP. AA digarap oleh Shader tentu saja bisa saya katakan “mengganggu” pekerjaan 320 Stream Processor pada kedua generasi Radeon HD terdahulu. Namun di HD4000 ini, saya kira 800 Stream Processor masih terlihat santai menggarap AA. Dan lalu karena AA sudah dikembangbiakkan dan dibudidayakan oleh Shader, maka wajar aja si ATI tetap mempertahankan ROP di 16 unit. Ke depan saya akan mencoba mengupas AA secara fokus, indeed dengan AF di artikel “HD4000 Image Quality Investigation”, semoga ada waktu luang.


Pros:
+ Harga terjangkau
+ Gaming performance already known as deadly mainstream card … kenceng!
+ Performa dengan AA On adalah fantastis
+ DX10.1; Video hardware acceleration (UVD 2.0); Cinema 2.0, HDMI w/ Audio HD 7.1, DTS, AC3
+ Single slot design, it’s slim
+ Hemat daya dengan TDP 110W
+ Silent … fan tidak berubah menjadi bersuara bising saat heavy load di aplikasi 3D
+ Catalyst WHQL update bulanan
+ Cross Fire X ready di mayoritas motherboard AMD dan Intel (2 – 4 slot PCI-E)
+ Dukungan after sales service dan garansi 2 tahun dari Sempurna, distro Powercolor di Indonesia

Cons:
- Temperature bisa masuk kategori panas (walau saya bilang itu masih normal untuk sebuah GPU dengan 800SP berkecapatan 625MHz desain board single slot), dan indeed sudah lolos Quality Control dari AMD selaku produsen kartu grafis dan Powercolor selaku partner produsen
- Minus bundle game dari Powercolor bagi sebagian pihak yang memperhatikan dan berstatus haus akan bonus bundle game


Score? Please feel free to submit your rating
Me? … 9.4
True value and a great candy gaming experience … SONG dah!

However, games are not 100% dependent on the graphics card; the Geforce 8 and 9 require a basic level of power, otherwise they are unable to exploit their 3D potential. The speed of the CPU should lie somewhere between 2600 and 3000 MHz; any lower, and the new graphics chips lose considerable performance.
