jajaja... la misma tarjeta antigua, con arquitectura antigua y nuevo sticker :lol:!!!

[alecu05]

k verguenza nvidia... donde mas le duele su gama media

Aparece el HD4770:

Fuiste veloz!

[FukTheOrder]

Ehmm corrijanme si estoy mal 4700 > 4800?

[lmchv]

Depende de que tarjeta de la serie 4800 le pongas enfrente. La unica que podria verse afectada es la 4830; veo dificil que alcance a la 4850 y ni que decir a las 4870, 4890 y 4870X2.

Bueno, finalmente el beneficiado va a ser el usuario, esa performance por $99 no es nada despreciable!

Aparece el HD4770

regresa el cooler grande (de aluminio dorado) :o

[Sieg2d]

AMD piensa descontinuar la fabricacion de la 4830 cuando salga la 4770 segun lo que leí y con razón, ya q es un tanto mas potente y a igual precio, de casualidad alguien sabe la fecha aproximada de su salida? buscando en varias paginas encuentro distintas fechas....

First Radeon HD 4770 Benchmark Goes Alive

Set to take the place of Radeon HD 4830, Radeon HD 4770 is powered by 640 stream processors, GDDR5 memory and core/memory clock of 750/800MHz (3200MHz, DDR). Thanks to the 40nm manufacturing process, AMD has managed to control the maximum TDP under 80W.

Fortunately, we’ve got hands on Radeon HD 4770 and given it a quick test. We’ve adopted Core i7 platform for the test, and the setting is the same as that in our review of 800SP Radeon HD 4830.

As we can see, Radeon HD 4770 shows a 3DMark Vantage/GPU Score of P8086/6639, compared with P8367/6891 found on HD 4850, which means HD 4770 only lags behind HD 4850 by 3.47/3.79%. If you wanna learn more about HD 4770’s gaming performance and power consumption, please pay close attention to our complete review later.

una auténtica joyita :D

[Ryoma-Echizen]

Esperando a mi precioso.

[Enkhil]

:o !!!

eso y con solo 128 bits, la gddr5 la hace
de aca un mes para que llegue y otro mes mas pa' que baje...

:o !!!

[Sieg2d]

No creo q tanto, aparte no hay prisa, no creo q se aloquen como cuando llegaron las ddr3 y algunos ya las kerian solo por el hecho de que era "lo ultimito" aca hay varios de esos si o no Enkhil ? :cheesy:

[Enkhil]

de hecho las ddr3 (ram) estan en el mercado nacional desde principios del 2007 (y aparecieron por el 2005/2006) y funcionaban con las p35 (intel)

las gddr4 y gddr5 estan basadas en ddr3 "ddr3 optimizadas para graficos" mientras que la gddr3 esta basada en ddr2 y la gddr2 en ddr1...
creo que todavia no salen tarjetas de video con ddr3 :roll:... asi como hay con ddr2
cuando aparecieron las 4670 en el huevonuevo estaban $90 y aca pedian cerca de $200, de ahi $150 hasta que llego a $120 :?

pd. ese puntaje esta muy cercano a la 4850 std (sin oc), de repente como una 4830 256bits y esa es solo de 128bits

[[ZaGaTo]]

agree
aqui se aprovechan mucho de los "compradores mañaneros"
si quieres ser uno de los primeros en tener nuevas tecs aqui en peru te suele costar mucho mas
yo le doy 1 mes o mes y medio para que llegue a un precio aceptable
digamos rondando los 150$

aun siendo de 128bits casi alcanza a la 4850 O_O, el GDDR5 ayuda bastante en ese sentido

[El Postman]

Tambien hay rumores de como sera la proxima serie de tarjetas que invadiran el mes de julio. En lo personal no puedo esperar, un par de X2 y juegas crysis a 200 fps jaja

ATI Radeon 5870 and 5870X2 specs revealed?
4/24/2009 by: Theo Valich - Get more from this author


German site ATI-Forum probably scored a coup of 2009 - according to their sources, ATI's RV870-based cards are already out at selected partners.
We cannot say was this leak was a reaction on our joint-exclusive story about nVidia's GT300 architecture, but one thing is for sure - ATI wants to bring out their Cypress board as soon as possible - planned for July 2009.
The alleged specifications of RV870 reveal that this chip is not exactly a new architecture, but rather a DirectX 11-specification tweak of the RV770 GPU architecture. Just like nVidia's GT300 architecture, the actual RV870 chip is manufactured in TSMC's 40nm half-node process, packing more transistors than GT200 chips. Regardless of what ATI says about nVidia and large dies, the fact of the matter is that ATI is making a large die as well - but the company will continue to use the dual-GPU approach to reach high-end performance.
The RV870 chip should feature 1200 cores, divided into 12 SIMD groups with 100 cores each [20 "5D" units], while RV770 was based on 10 SIMD group with 80 cores total [16 "5D" groups consisting out of one "fat" and four simpler ones]. Thus, it is logical to conclude that when it comes to execution cores, not much happened architecturally - ATI's engineers increased the number of registers and other demanding architectural tasks in order to comply with Shader Model 5.0 and DirectX 11 Compute Shaders. The core is surrounded with 48 texture memory units, meaning ATI is continuing to increase the ROP:Core:TMU. For the first time, ATI is shipping a part with 32 ROP [Rasterizing OPeration] units, meaning the chip is able to output 32 pixels in a single clock.
When it comes to products, ATI plans to launch four parts: Radeon HD 5850 and 5850X2 in more affordable pricing bracket and HD5870 and HD5870X2 for the high-end parts. While there were no clocks for the Radeon HD 5850/5850X2 parts, alleged clocks for HD5870 and HD5870X2 reveal that for the first time, an X2 part is clocked higher than a single-GPU part. Was this a requirement of SidePort memory interface, we are not aware atm. German site Hardware-Infos placed all of the data in a very convenient table, which we are running here with permission. Their story also contains more data about the upcoming ATI RV870 architecture.

These units should result in 2.16 TFLOPS for the HD5870 and 4.56 TFLOPS for the dual-GPU part. Yes, you've read correctly - we are going from 1TFLOPS chip to 4.6TFLOPS within 13 months. Is it now clear that CPUs are in a standstill when it comes to performance improvements? The biggest question though is - while there is no doubt that ATI pulled another miracle out of their hat with a brilliant on-time execution, releasing a 40nm part that will be relatively cheap to manufacture. BUT - can it beat nVidia's GT300 and by how much?
Some journalists allegedly have miracle 8-balls and claim that the ATI cards will blow nVidia out of the water. We are not so certain... stay tuned.

agg seria alucinante k ati sake una 5870 de 512bits gssr5 (no 256x2)
