You don't even have to modify the CPU or GPU chip itself!
I could put an entire chip in the ceramic or metal cap that COVERS any given CPU/GPU which can be powered parasitically via induction, direct connect to leads, etc. This chip-under-the-cap can even include a Fractal Antennae design or a very narrow band antennae to send data over low-bandwidth but long-range/penetrating wavelengths. The emitted signals would likely be seen as extraneous noise but modern DSP (Digital Signal Processing) could recover actual compressed/encrypted data over long periods of time. Even a Faraday cage won't necessarily help because any TEMPEST (look it up!) signals screening would be specific to certain wavelengths usually in the 1.5 to 6 GHz bands that cell phones and wifi use. Goto Terahertz or lower than 1.5 GHz or even acoustic communications bands and then even the typical mesh-screen or punched metal Faraday cage will be compromised. Only a FULLY ENCASED SOLID SHEET Tungsten, Copper And Polymer Faraday Cage will block those signals!
In some cases the signal may need to travel only a few inches/cm or a few feet/metres since the destination storage medium may be embedded into clothing, jackets, buttons, shoes, or disguised as common personal gear, etc. A person who works in a sensitive location MAY NOT even be aware they are the external data transmission medium since THEIR personal clothing/goods may be intercepted and modified by external spy agencies. Once the targeted employee walks out at the end of the day, an external system can intercept and download the latest data using non-physical extraction (i.e. wireless comms)
The typical front door security/user entry system and even a physical body search would NOT detect these PASSIVE data storage devices which can be as thin as a postage stamp or as small as a pencil head! (or they might actually BE embedded into pens/pencils/erasers/sheets of blank paper!) Even teh X-ray system wouldn't detect the passive device since the typical security guard would NOT know what they are looking at on-screen and just "Let It Go Through!"
