los últimos chipsets de AMD íbamos acumulando distintas preguntas
Sobre los últimos chipsets de AMD íbamos acumulando distintas preguntas y nunca teníamos tiempo para responderlas, finalmente en un último esfuerzo antes de terminar el año vamos a intentar conseguir algunas respuestas para ver, performance level, how they affect different elements, such as using DDR2 or DDR3 memory, using technology Sideport, if there are significant differences in performance between AMD's latest chipsets, etc ...
Is it worth Sideport technology?
Sideport is a dedicated memory for graphics chip integrated graphics chips found in the chipset AMD 780G, 785G and 790GX, although there may be some more. Normally this is a 128MB memory chip with 1066-1333MHz DDR3, surely this can vary depending on the assembly, but in general we see DDR3-1066 for chipsets that use DDR2 and DDR3-1333 for chipsets that use DDR3 the system. The idea of \u200b\u200bSideport is that the IGP performance look better with this memory dedicated exclusively to the VGA "steal" less memory of our computer system and the overall team performance look less burdened. Try to see it, although in this case we could only prove SidePort a 780G board, but we watched the results can be extrapolated to many more solutions.
be recalled that the technology exists for the VGAs Sideport MultiGPU, but it seems that there has been very successful, and we know many details of it, but advised it to avoid confusion with the name of technology.
"DDR2 or DDR3?
Although DDR3 memory now and is priced almost equivalent to that of DDR2, for a long time this was not the case, and therefore many users DDR2-based computers. The answer now is obvious: better DDR3 because the most modern, consume less and is the standard for the future, but what we want is to quantify the differences, but in this case given that the system memory is shared by IGP graphics chip of these chipsets and therefore the VGA also benefits from the use of this faster memory. Does the problem? shared memory for when we can not distinguish which of the improvements come as the system runs faster DDR3 memory to have and what performance improvements are due al aumento de ancho de banda de la memoria del chip gráfico.
¿Perdemos mucho rendimiento 2D con VGA integrada en vez de VGA dedicada?
Aunque deberíamos pasar más pruebas de las que haremos intentaremos comparar algunos tests puramente de CPU y ver si hay diferencia de rendimiento en la misma placa entre disponer de sólo el IGP integrado o si al añadir una VGA dedicada y no tener que compartir memoria del sistema con la VGA ganamos rendimiento, hace años esto sí que era un lastre importante, veremos cómo andamos hoy.
En el caso de una VGA dedicada ¿Importa el chipset?
Cada chipset tiene sus particularidades y sabemos que hay varias funciones que no se pueden disfrutar con algunos chipsets, pero in the case of one simple VGA, is there significant performance differences between using a 780G or 790X chipset, for example? We'll see.
