Rv730xt
320 Shaders and fixed FSAA
We've heard that RV730XT, an entry level card scheduled to be launched in September, will be fast enough to beat Radeon 3850 performance.
This will be quite visible in FSAA and Anisotropic environment simply as Radeon 4000 chips have the FSAA unit fixed and the HD 3000 including Radeon 3850 were not that great with FSAA done via Shaders.
AMD will put some additional pressure on Nvidia and it looks that ATI will have some healthy GPU sales thorughout the complete product range. Nvidia is late with 55nm, doesn’t have DirectX 10.1 or Shader 4.1 and at the same time, they are slowly losing in performance in almost every market segment.
Nvidia already got its wake up call and its time to do something about it. RV710 and RV730 will once again hit Nvidia really hard, just as RV770 and R700 did in mainstream and high end.

Has native HDMI and DisplayPort support
The first sighting of an AMD reference card based on the RV730, which in its consumer guise is expected to be known as the Radeon HD 4600-series has been spotted and it's claimed that the card in question is more specifically a Radeon HD 4670.
Don't expect this 55nm GPU to be a performance monster, despite the fact that it has 320 Shaders, as it's still limited by a 128-bit memory interface, which will limit the performance of this card.
However, it's expected that it'll beat the Geforce 9500 quite easily, as the Radeon HD 4670 should have its GPU clocked at 700MHz with the GDDR3 memory clocked at 900MHz (1,800MHz effectively) and with all those Shaders, this card should still be an interesting product in the sub US$150 market.
Expect to see 512Mb and 1GB versions of this card and we wouldn't rule out the possibility of a cheaper 256MB version as well. The cards will offer DVI, HDMI, DisplayPort, D-sub and TV-out connectivity, although we have to wait for final production cards to see what AMDs partners will add in terms of ports on these cards.
Our only concern is that the reference cooler looks quite small and noisy, but hopefully AMDs partners will step up and provide some better cooling solutions. With an expected TDP of 70W we might even see some decent passively cooled cards.
