"Today appeared new information about the RV870 chip . Associate reports that this 40 nm chip models will appear at the end of present year, and to the end of first quarter 2009 it will reach the series production .
The quantity of stream processors on RV870 chip can grow up to 1000 pieces. Their resulting computational performance can reach 1,5 teraflops.
The memory capacity on RV870 video card can reach 150-160 Gbit/s. If we considers that Radeon HD 4870 with 256- bit bus and 3600 MHz DDR
The RV870 core area will decrease from 256 sq. mm, in RV770, to 205 sq. mm. This will allow to create the two-chip graphical solutions easily." memory frequency ensures a capacity at the level of 115,2 Gbit/s, RV870 can raise the memory frequency to 4800 MHz DDR with constant memory bus. Qimonda company already released GDDR5 microcircuits working at frequencies up to 5000 MHz DDR .
Radeon HD 5870 X4 (Dual MCM, 800MHz Core, 2GB 1200MHz GDDR5) - $649
Radeon HD 5870 X2 (MCM, 800MHz Core, 1GB 1200MHz GDDR5) - $349
Radeon HD 5870 (800MHz Core, 512MB 1200MHz GDDR5) - $199
Radeon HD 5850 (600-650MHz Core, 512MB 1100MHz GDDR3) - $129
Integrated Memory Controller
960 or 1000 Shaders
~850 Core clocks
~4800 GHz Ram clocks (can easily overclock to low 5GHz)
1 - 4GB RAM Configurations depending on how many GPUs
256 Bit RAM, 512 Bit RAM possible with revisions.
dx10.1 now with dx11 for refresh revision
205 mm² Die-Sitze
If you hear of more rumors, post here! This is exciting for those gaming at 1920x1080 or higher resolution and have the best overclocked core duo cpus. I wonder when they will have giant LCD monitors above 2560x1600? Otherwise the hd5870x4 is gonna be overkill!
Info:
HD 5450 -> 640 SP + 16 TMUs (1 master chip)
HD 5650 -> 1280 SP + 32 TMUs (1 master chip + 1 slave)
HD 5670 -> 1920 SP + 48 TMUs (1 master chip + 2 slaves)
HD 5850 -> 2560 SP + 64 TMUs (1 master chip + 3 slaves)
HD 5870 -> 3200 SP + 80 TMUs (1 master chip + 4 slaves)
