Inkampani ye-Intel Wonke Amalungelo Agodliwe. I-Intel, ilogo ye-Intel, nezinye izimpawu ze-Intel yizimpawu zokuthengisa ze-Intel Corporation noma izinkampani ezingaphansi kwayo. I-Intel iqinisekisa ukusebenza kwe-FPGA yayo kanye nemikhiqizo ye-semiconductor ekucacisweni kwamanje ngokuvumelana newaranti evamile ye-Intel, kodwa igodla ilungelo lokwenza izinguquko kunoma imiphi imikhiqizo namasevisi nganoma yisiphi isikhathi ngaphandle kwesaziso. I-Intel ayithathi mthwalo noma isikweletu esivele ngenxa yesicelo noma ukusetshenziswa kwanoma yiluphi ulwazi, umkhiqizo, noma isevisi echazwe lapha ngaphandle kwalapho okuvunyelwene ngakho ngokubhaliwe yi-Intel. Amakhasimende e-Intel ayelulekwa ukuthi athole inguqulo yakamuva yokucaciswa kwedivayisi ngaphambi kokuthembela kunoma yiluphi ulwazi olushicilelwe nangaphambi kokufaka ama-oda emikhiqizo noma amasevisi.
*Amanye amagama namabhrendi angafunwa njengempahla yabanye.
