FUD Zilla reports MSI will use the same PCB of its Radeon HD 4850 graphics card for the new Radeon HD 4830. This means the Radeon HD 4830 from MSI will have a 4+1 phase power design which should resulst in more stable power, better overclocking, lower power consumption and longer lifespan.
MSI's HD 4830 will therefore come with 4+1-phase power design where four phases will be for GPU and one for DDR3 memory. According to the slide that we managed to see, this will result in reduced load on each power phase, lower temps of the PWM part, improved power efficiency, longer lifespan and most importantly, better overclocking capability.
Other features of MSI's HD 4830 include solid state chokes and solid capacitors for the GPU and memory power module. We know that MSI will have two versions of the HD 4830 card and that both will probably have the same HD 4850 PCB.
