My PSU is a XFX TS 550W with Haswell support and it comes with the connectors below. Is the 4+4 pin and 8 pin the same?
1 x Main connector (20+4Pin)
1 x 4+4 Pin ATX12V / EPS12V
1 x EPS 12V 8-pin ATX12V / EPS12V
Up to 6 Peripheral (2x Triple Molex 4pin)
Up to 9 SATA (3x Triple SATA Cables)
1 x 6-pin PCI-E
1 x 6+2-pin PCI-E

So both 4+4 Pin ATX12V / EPS12V and EPS 12V 8-pin ATX12V / EPS12V will work, what is the difference?

None. You have 2 in case you have a dual cpu motherboard.

That's correct.

Strictly speaking, the ATX standard specifies a 4 pin auxiliary power connector and the EPS standard specifies an 8 pin auxiliary power connector and an additional optional 4 pin tertiary power connector. On mid range power supplies (those under 1,000 watts) it's common to see a 4+4 pin connector which can satisfy the requirements of both the ATX and base EPS specifications. High end power supplies often have a single 8 pin EPS connector and a 4 pin connector which can serve as either an ATX auxiliary connector or an EPS tertiary connector.
If you're confused by what I mean by a tertiary connector, see the Rampage IV Extreme motherboard, it has a 24 pin main connector, 8 pin EPS auxiliary connector, and a 4 pin tertiary connector. Since the tertiary connector is optional, most consumer motherboards do not include it.

EDIT: As i7baby mentioned, dual-socket motherboards have two 8 pin EPS connectors. Very high end PSUs will have both an 8 pin and a 4+4 pin or even two 8 pins

1 x 4+4 Pin ATX12V / EPS12V
1 x EPS 12V 8-pin ATX12V / EPS12V

Either one of these ^ , they have 2 sometimes for extra power for boards that are used for serious overclocking.

Lol, i do not understand why they would expect someone to have a dual motherboard. I understand some people dew but very few do. That is like saying it come with a Plutonium power core in it that will power your PSU but requires Plutonium, not many people will have it, lol.

It's for overclocking power on high end boards.
