ten graf kazdopadne nezobrazuje percentualny pomer

ten graf kazdopadne nezobrazuje percentualny pomer

stačilo prečítať si môj post:

6.) zhrnuté: RV870 je o ~30% väčší čip ako predchodca, má o viac ako 100% vyššiu komplexitu (2,15 miliard tranzistorov) a dosahuje v priemere o 1/2 vyšší výkon ako predchodca a trochu menej voči HD 4890.

a logicky usúdiť, že tá prerušovaná čiara má znázorňovať priemerný % nárast výkonu voči GTX 285. Graf teda začína pri 80% a jednen "odsek" je 20%.

Ale sudruzi z Chipphell ušetrili toto trápenie pre väčšinu:

pekne marketingovy navrhnuty graf

[crux2005]

Normálne, nad tým by som sa nevzrušoval.

lol, na tej karte je speaker

inak vykon paradny podla mna

RV870:



preto boli pred launchom chybné interpretácie typu "dual-core"

EDIT: len vydarený fake

We told you about Juniper cards earlier and now let's check out their system requirements. Looks pretty similiar to Radeon HD 4770 except you need at least a 600W for Crossfire.

* PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
* 450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)
* Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU" onclick="window.open(this.href);return false; for a list of Certified products
* Minimum 1GB of system memory
* Installation software requires CD-ROM drive
* DVD playback requires DVD drive
* Blu-ray™ playback requires Blu-ray drive
* For an ATI CrossFireX™ system, a second ATI Radeon™ HD 5770/5750 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required

Another bit of information, both cards are double slots and HD 5770 is 8-layer and HD 5750 is 6-layer. Pricing ranges from US$149-199. Also, there is another cheaper Juniper board on the horizon.

20 SIMD Cores
- Each SIMD Cores contains a 5D ALUs, a total of 1600 ALUs

80 Texture Unit
- Each SIMD Cores are four TU

Has two Rasterizer unit, Hierarchial-Z units are double (two), but the Geometry / Vertex Assembler is still one each for

- The use of SIMD Core implementation of the triangle interpolation, no longer using a separate hardware unit to perform this operation, SIMD Core this added interpolation instructions (lrp?)

Improved the performance of Constant Buffer

Faster Geometry Shader Performance

OpenGL context, achieved a 12-bit sub-pixel accuracy, raising the Line rendering performance and speed of operation clippiing

Double-precision performance of 544GFLOPS.

IPC Enhancements
- More flexible implementation of dot product instructions
- To achieve single-cycle MUL, dependent ADD instruction Co-issue
- Support the provision of hardware implementation of the SAD instruction can be achieved through the OpenCL

Aspects of texture units and cache
- Complete the second element 68B bilinear texture filtering
- Completion of 272B 32-bit per second texture fetch
- L1 tex cache bandwidth 1TB / s
- L1 to L2 bandwidth of 435 GB / s
- Each memory controller with 128KB L2 cache
- Support for texture 16k * 16k
- Support for DX11 in BC6 / 7 Compressed Texture
- Perfect angle dependent anisotropic texture filtering, the performance of decay rate consistent with previous AF algorithm
- The details of the ideal degree of adjustment ensures a higher quality of texture mapping

AA, it will basically single-cycle performance of the overall fold up, but the texture units are now available from compressed AA color buffer to read data, and will provide Supersampling AA (previously only in the RADEON 8500 the public before)

Stream Computing aspects
- Follow the IEEE 754-2008 precision
- Provide NVIDIA GT200 introduced Coalesces Memory Write
- Scatter operation can be done single-cycle 64 32-bit values, the generation is 32, but ...
- Support for 32-bit atomic operations
- Flexibility to configure the 32KB LDS (each SIMD core of a LDS, each 32kB)
- Full-chip has a GDS (Global Data Share), size of 64KB
- To achieve global synchronization

načo čakať na niečo oficiálne od AMD

[crux2005]

Radeon HD 5870 sa má v 2D podtaktovať na 157/300(600)MHz a znížiť napätie z 1,063V na 0,95V

vau, žeby už konečne začali podtaktovávať aj pamäte? to yb vysvetľovalo tú maličkú spotrebu v 2D
