An Acer VA50HCCR (U3E1) laptop motherboard with an i7 CPU and HD4000 Graphics has AGP listed by multiple sites as its GPU interface, but the NVidia GT640M supposedly is PCIe 3.0. Did Acer modify the 640 with the old 2.133 GB/sec memory bus, or is "AGP" in this instance just used generically ("Accelerated Graphics Processor")?

The latter, Intel's HD4000, 4200, 4600, and 5200 are their AGPs. Generally, GPUs are broken down into either discrete like the 640M or integrated like the 4000.
More often than not the discrete cards will always out perform the AGPs but both AMD and Intel have made head-way with their integrated graphics and many of the newer AGPs (like the 5200) perform better than low-end older discrete cards.
Here is a link to a great tutorial on AGPs: http://www-pc.uni-regensburg.de/hardware/TECHDOK/intel_agpoverview.htm

Thanks for the prompt responses, markaflias and minerva330
I believe AGP is sometimes used to indicate the presence of a peripheral GPU (rather than none at all), but when referring to a specific interconnect, it cites one that's been rendered obsolete by two generations of PCI-e, with a currently sparsely-used 3.0 version already built into some new hardware. The acronym applied to such products as Intel HD Graphics is IGP, for Integrated Graphics Processor.
AMD uses APU (Accelerated Processing Unit) to describe their new A-series CPUs with onboard graphics (on the processor die like Intel's Sandy/Ivy Bridge and Haswell, or in the chipset; I'm not sure)---when in doubt, make 'your' product sound like 'theirs', right?
.
Agreed.
Thanks for the link to the old tute; it was fun brushing up (1997, with the advent of Pentium II).
A laptop less than three years old isn't likely to use an AGP interface, so I'm just going to assume that somebody typo'ed that specs chart.
