newer CPU on previous generation chipset = automatic performance loss?

[7point5]

to elaborate: since a given socket can cover 2 generations of chipsets/mainboards (for instance LGA1155 CPUs like Sandy & Ivy are handled by both P67 boards (with bios update) and H77/Z77 boards, and LGA1150 CPUs like Haswell & Broadwell are handled by both z87 boards (with bios update) and h97/z97 boards), question is: _________________________________________________________________________________________________ if a newer cpu is put on an board with previous generation chipset (after having updated bios) will there be a performance loss/bottleneck caused by the older board? _________________________________________________________________________________________________________________________________________________ for instance if I put a broadwell cpu on a haswell board (by that I mean a z87 chipset board) or an ivy cpu on a sandy board (eg. p67 chipset) can the cpu still be used to its full power or will there be a performance loss compared to the same cpu on the next generation chipset board?

To elaborate: since a given socket can cover 2 generations of chipsets/mainboards (for instance LGA1155 CPUs like Sandy & Ivy are handled by both P67 boards (with bios update) and H77/Z77 boards, and LGA1150 CPUs like Haswell & Broadwell are handled by both z87 boards (with bios update) and h97/z97 boards), question is:

 

If a newer CPU is put on an board with previous generation chipset (after having updated bios) will there be a performance loss/bottleneck caused by the older board? For instance if I put a broadwell cpu on a haswell board (by that I mean a z87 chipset board) or an ivy CPU on a sandy board (e.g. p67 chipset) can the CPU still be used to its full power or will there be a performance loss compared to the same CPU on the next generation chipset board? (the generation that was developed at the same period as the CPU: z77 for ivys, z97 for broadwells)

 

PS. and by performance I mean only the ones users care about: framerate in 3D games, raw computing power like compression & divx encoding, u get the picture

PPS. and to make the question worthwhile let's assume the most powerful CPU is being used for that socket (e.g. an Intel i7 3xxx or i7 5xxx with 4 real cores & 8 virtual cores with HT enabled in bios)

again I researched this extensively & can conclude that no one on the internet knows the answer to this

I reckon the performance difference would be negligible to non-existent. Obviously using older motherboards with newer CPUs does mean you miss out on the features that the newer chipsets/motherboards offer. e.g.

 

• Z97 adds support for PCIe M.2 and (non-existent) SATA Express SSDs which Z87 lacked.
  
• 100 series (Skylake) motherboards include DDR4 support (thereby also increasing the max supported RAM to 64GB with 16GB DIMMs) and PCI Express 3.0 (good for NVMe SSDs).
  
• 300 series (Coffee Lake) motherboards officially support Intel's 6-core CPUs.
  

Wikipedia has more details on the chipset differences.

Works fine for me. Perhaps it might be worth switching to the standard or basic editors in your Edugeek profile settings.

(k thx apparently the "enhanced editor" sux I switched to standard)

 

I know I meant not the extra features I only meant in terms of raw power

 

ok a concrete example:

 

imagine a z87 board (ie. meant for Haswell CPU) and imagine it's flashed to support Broadwell CPU (which is also LGA1150 like Haswell, but is originally meant for z97 boards)

 

now imagine I put the most powerful i7 Broadwell CPU on that z87 board, then run a game that can use the full power of that CPU

 

 

 

>> the only question is: will there be a lower framerate, compare to that same CPU on a z97 board?

btw I realize only someone with the highest level of tech knowledge can truly answer this so if there's any IT senior engineers reading this maybe they could provide a definite answer?
